I'm a software developer in Berlin and find these videos relaxing: Watching somebody else find a complex problem and know it's going to get fixed in about twenty minutes, without me having to get involved. Aaaaah! :D
I feel you man :D Same story, different city 😁 It's also nice seeing someone giving a damn about his job and not screwing a project up until you're called to fix the burning hellhole 😂
Love it I’ve been a painter for 30 years recently retired but I am recently mesmerized by your videos didn’t think there were any good contractors left in this world but you proved me wrong with your OCD and you are very knowledgeable in your craft enjoy watching the videos very much keep up the good work truly the good customers will recognize that
Great video and admire your work ! Have to mention about safety to work on equipment before turn disconnect off. It should check for grounding as well. I was called to condensing unit for walk in freezer. It was dead and verified no power on L1 L2 L3 like you do. Double make sure to use my NCV pen to verify and it was still LIVE ! It was grounding . Someone did bypassed disconnect switch by wires L1 without use fuse. I did encountered several like this one. Never hurt to check for grounding sir.
Excellent work as always. You should know I watch these videos sometimes 3 and 4 times just to help keep me mentally sharp and catch tips and tricks. Your demeanor allows for a nice chill mood making the videos even easier to watch. Thank you.

Just a small note. I always tighten, back off, and re-tighten the lugs when clamping down on solid core wire, just like you do with set screws on a shaft. It seems to make up for whatever happens with expansion and contraction that looses the connection over time. Good video as usual.
First thought was evaporator wires rubbing when you said the evaporator was on the same circuit as the condensing unit. Good job repairing it. I can get most blades balanced out by hand as long as the blades are not cracked.

Nice job. I'm really enjoying your videos. I like how you explain step by step what you're thinking while troubleshooting and add in the real world tips during the repair. I also really like how you add in the post job commentary from the office.
Man I love watching these videos. I am a doctor and love the similarities on how he diagnoses the issues. You have to know the order of operations in case something doesn’t work right. Wish he lived on the East Coast of the US.
Nice job! A couple comments that might be useful. On that rusty electrical box, I think instead of trying to seal the upper conduit, I might have put a 1/8" or 3/16" hole in the bottom of the box to let it drain. Sealing the down conduit is just going to get any water in the conduit pooling in that top box fitting and rusting it out. Along the same lines, in the contactor box on the roof, I noticed you left some wirenuts sideways on the bottom of the box. I've gotten in the habit of trying to keep wirenuts pointing upwards to keep moisture from pooling in them. Likewise I keep them off the bottom of a box if at all possible to keep any pooling water or small vermin from making a home inside the wirenut.
Funny when I saw the hot sauce... reminds me of a time when I went to do a service on an CVD ice machine at a popular fast food joint. I opened the ice machine and found tons of opened hot sauce packets inside the unit just behind the evaporator along with straws and napkins torn up. I wondered who the hell put hot sauce packets inside the unit till I saw rat dropping. The hot packet sauces where right next to the drink/ice dispenser and this rat would grab it and take it inside the ice machine and enjoy it in there. Customer still wanted unit running 🤦♂️
Hi, I am watching your vlogs from the UK and have recently gone into AC works. You have the same principles as me so keep up the good work and keep making valuable videos.

Some of the guys I used to work with would bust my balls calling me Curious George when I would look at things lime you do/did (using your senses and found the wires rubbing in the evap coil). Granted, I have caused problems doing that! It's a skill that requires practice knowing when to leave shit alone.😁 But, I have also found things multiple other guys couldn't find! So I became more diligent with my explorations, more careful, methodical. I can't express enough, how much you're videos have helped me understand how this stuff works! I did a year in trade school, a year working for a refrigeration commpany, 12 years working for an a/c company. Struggled more than I should have cuz breaking balls was easier, more satisfying than teaching! And Old Curious George here has a hunger to learn! I wish your videos were around sooner. I went to school in 2003. Even though I've been out of the trade for a few years and my body won't let me go back, your videos have gotten me inspired. Even if I never go back, I get SO MUCH from your videos!! Thank You So Much Dude!!! Not nearly enough technicians like you in the trade!! I wonder if in one of your videos if you could talk about your apprenticeship and who taught you and what it was like for you. ok I've rambled enough. Peace!
I had a similar situation with an air curtain but breaker was not tripping . But I was getting weird voltage readings 120 to ground on each leg but only 7.68 volts across both legs. But in my case it was undersized wire nuts and vibrations made it come loose. Shorted to unit but tested it only using continuity.
I've only seen an undersized wire nut once. It also had a loose wire in it (the proper way to use a wire nut is bundle all the wires together and twist the exposed copper into a pigtail, THEN screw on the wire nut. NEVER use the wire nut itself to hold the wires together) and the way I noticed it was from the heat discoloration on the side of the junction box. When I pulled the wires out, there was only half a wire nut left, the rest had melted/burned away from the overheating due to the loose wire connection. My best guess is I was 2-4 days away from an Electrical Fire that likely would have burned my house down. And no, I didn't wire up the Circuit originally, that sloppy connection was done by the Idiots that I bought the house from. I've owned this house for 5.5 years now and I'm STILL finding badly wired Circuits. If I hadn't bought this house from an Estate Sale (I'e: from a dead person), I'd report their asses to the City Code Enforcement people and have them Charged with Performing Permit Required Work without the proper Permits. There is no Statute of Limitations on that and the Fines can be VERY high depending on 3 major Factors: 1) How much Illegal work was done (1 or 2 circuits in a home, minor fine; Illegally wired the whole house, major fine). 2) How bad is the work (all work done to Code, just no Permit, minor fine; nothing even close to Code and is highly likely to burn the house down, MASSIVE fine). 3) How Polite are you to the Inspector (Been very Polite and Respectful and accepted the Inspector's Criticism and Corrections with Dignity and Grace, minor fine; Snarled and Cursed at the Inspector and resisted their efforts to inspect the work, HUGE Fine AND you'll be forced completely open up everything you've touched for their Inspection THEN rip it all out, pull the Proper Permits and do it over from scratch at your expense)... Be nice and Polite to Code Inspectors, it WILL save you time and money in the long run...

Cord Grips was the word you were looking for. Would have been interesting to see how bad the inside of the contactor was. I don't deal with contactors too much becasue of the HP of motor we deal with but I have seen some pretty bad Size 3, 4 and 5 Starters with contacts totally eaten up or even starters that blew up going phase to phase..

Young guys. Make sure you check the spade connections at the compressor terminals. Many times, I have found loose connections that make intermittent issues. Most of the time a pair of needle nose can make a tight connection. Also, I like to use dielectric grease on the connectors. It wicks moisture and prevents rust.
was all fuses the same rating in the disconnect? the middle one looked like it was cooking hot too many times, but maybe just different copper blend and manufacture
Hi mate, great video as usual thank you. I have a question regarding the dual port suction service valve you made reference to (21 minute mark). If that valve is front seated and your service gauge was on the port furthest away from the spindle, would you be reading the compressor suction pressure or the suction line pressure. Put another way, does front seating that valve isolate the compressor from the suction line. Many thanks in advance if you get time to answer 👍🏼
lol ive seen that happen about 3 times so far, and once i found several wires or wire, a neutral that was grounding in a freezer evap and fans would keep running because the fan delay cut the neutral off lol, it was odd as i remember disconnecting the neutral and fans keep running lol....fyi do not use safetys or switches in neutral
As far as the condenser fan motor drawing slightly more current isn't a big thing at all. Even if it drew one amp more than normal shouldn't put things in panic mode. If your line voltage was a little lower than normal, the current draw will be higher. Nothing to sweat. If however, the fan was drawing 5 or 6 amp more current, then it's cause for concern. If the bearings were starting to seize, you will have more current draw. Of if the cap is very leaky. When a capacitor becomes very leaky, at that point it turns into a resistor. Great videos. Keep 'em coming :)
When i have a contactor that is "up side down", from how the original one is mounted, i don't EVER install it up side down and just flip the cover. Notice how it is supposed to mount. The top mounting point should be "closed" and the bottom is slotted. It should NEVER be mounted with the slotted side up, for safety. Instead, unscrew the mounting bracket off the back of the contactor and simply turn it around 180° and screw it back on. The contactor will mount correctly and the coil voltage wires will mount in the correct location.
You realize that in order for it to come loose in the upside-down position, one screw would have to come totally out, and the other one loosen, and if it's that bad, the loose one is probably going to fall out anyway. The margin of safety "lost" by installing it upside down is about 5 percent, and would only cause issues in seriously bad conditions where it's probably the least of your worries lol Many devices have slots on all positions so they don't even have that slight safety margin. Now, on some devices it's easy to flip the base, and it's not bad to put the slot at the bottom, but it's not really a serious safety issue.
@@ke6gwf wow! Only 5%? Huh! Where did you find that stat? Did you research that with Underwriter Laboratory? Or did you just make that up to make yourself look smart? But anyway, I was taught to install them a with the slots in the correct postion. You can mount yours any way you choose. Have a nice night.
@@mikec.2746 Thank you for demonstrating the difference between an Installer and a Technician. You do it a certain way because a person you consider to be smarter than you told you to do it that way. A Technician looks at a situation and makes their own decisions. You know what the closed hole is really for? In case you are mounting a new unit, you can drill one hole, put the screw through the mounting hole, and hang it from one screw, while you mark or drill the other holes. That's why it's centered. Some contactors and similar devices have them, some have all slots, and some have no slots. UL doesn't care about slots or holes, and it order for it to matter if the slot is up or down, one screw has to be completely gone, at which point UL and OSHA and IRS and MSHA are totally violated anyway. Oh, shocker, they can also be mounted sideways! What do you do then?!? So unless you can show from a manufacturer data sheet, or a code requirement that the slot direction is dictated to be down, than you are just passing on what some individual told you as gospel, and as the only PROPER way to do something. And if you want to install them that way, great! And if I am installing one that has a base that easily rotates, I likely will do so if it makes mounting easier, but not all do, and so making it a hard rule doesn't help. If you had simply said that the bases can often be flipped to keep the slot at the bottom, and it's safer that way, you could benefit the conversation without making any blanket claims that others are doing it wrong.
@@ke6gwf Did you seriously just take a shot at installers???? Just to TRY to make yourself seem superior??? The installers I have ever worked with or employ are top notch people that have nothing but my absolute respect and admiration. How dare you put a group down just to make you feel better about yourself!! You are a real class act. I do take comfort, however, of never having to know you personally. Especially with your superiority complex. I still can't get over that you would take a shot at people in our industry just to make yourself seem smarter than you really are. You must be a very lonely person. Have a nice life.
@@mikec.2746 Sorry, I was not referring to people who install new units, I was comparing two mind sets. For instance, in heavy equipment operation, you have "steering wheel holders" and then you have "operators". They both do the same thing, but one is able to figure out how to do things, the other has to be directed by someone else. So by "Installer" I mean someone who just installs parts or repeats what they are told by someone else, who isn't able to step back and look at the big picture, or design solutions. And by "Technician" I mean someone who is able to troubleshoot and design solutions and figure out things on their own, instead of just relying on the directions of others. One type of person, you have to give them directions on a job, and if they run into anything unexpected, you can expect a call from them needing help to figure out what to do. The other type, you can send on a job, and you know that they will get the job done, no matter what they run into, because they are able to figure it out. For instance, if you were using a contactor with a riveted base, and you needed the coil terminals on the other side, what would you do?
Vibration and wires leading to a short. Can that happen? Oh yeah. Good methodical diagnosis. The rust and water in that box looked scary. Going a little heavier on the contactor was a good move. Condensor fan motor looked like it was loaded up with dirt. Always wonderful going in after someone else's work.

Do you get to work on chillers much? I’m fortunate get to do a little bit of everything. Mostly air con but dabble in coolrooms and freezer rooms aswell
also one way to see which is cooler and which is freezer (0:41), is that the freezer has a substationally larger vent opening, because it needs to move away more heat.
the receiver looked to have slot style packing nut for something like a pin spanner wrench or spanner socket. probably that way because of total diameter or to keep people from tampering or a hook spanner wrench, couldn't think of it when I wanted lol.
You checked to see if power was off but where did you put your ground too? Ypu only had the power side probe and not the ground side probe. So where did you have ypur ground touching?
Again, thank you very very much for your videos. I truly appreciate all the effort you make setting the camera bc it is not easy sometimes. Although, It totally looks like it comes out naturally already. I bet if you go to a job and you don't have your camera in, you fell like missing something haha. Thank you.

Are these units enclosed in the big housing to try and protect the components? Seems like a logical idea to try and maintain the longevity of the equipment.
And now the wiring looks fare more "official". If you need to run un-jacketed wiring though a metal clamp short pieces of neoprene hose can come in handy. Snap in plastic bushing for the ends of BX/MX cables and conduits should also be in place, to prevent chafing.
those cables should have been in a rubber grommet, or a blob of silicone to prevent rubbing. kinda rough. The replacement wiring is soooooooo much better! GG!
When things have to be taken apart multiple times, how do you guys deal with the sheet metal screws stripping out? It seems like after 2 or 3 cycles they don't hold well any more. And on thinner metal, they hardly grip on the first use.
Yeah that happens for sure especially when people use impacts to tighten and loosen them... when it does happen I just go up in size on the screws and hope that they dont continue to strip them...
I hear it's best to replace a breaker after about 4 or 5 trips because they essentially become derated. Also I want some of those insulated screw drivers when I replace wall outlets and such around the house.
Thank you for the great videos. I also like how what I follow on FB will show up here later. Serious question though, are you that concerned on being .1 over amps? To my very limited knowledge, you allow 10% differential when testing electrical.
.1 isn't bad but usually as the motor heats up it will continue to draw higher amps. Also if the capacitor is weak as it weakens further it puts a lot of strain on the windings in motor.
2 things that would increase amp draw on a condenser motor; someone put to aggressive blade on it or if coil is plugging up though your pressures looked good but someone could've tried to increase air flow with more aggressive blade to compensate for plugged condenser coil. ( be surprised how many dirty coils i've come across with that problem; then again maybe you wouldn't)
Plugged coil would actually decrease amp draw. You know how when you block the air flow through a fan, it speeds up? That's because it takes less energy to swirl air around, then to propel air. So a dirty coil will reduce air flow through the coil, thus making the fan just swirl air behind the coil, which uses less current. Now, you are right, they may have put a bigger blade on, which would increase current.

Same story, different city 😁
It's also nice seeing someone giving a damn about his job and not screwing a project up until you're called to fix the burning hellhole 😂
Same, diff country though.
It always helps, on any project, to take a picture before disassembly.
Especially when you are disassembling your own camera!
I never considered that running wires parallel to a mounting point prevents rub outs. Makes a lot of sense. Good tip
Yeah I was thinking the same thing after he mentioned it. I’ve made that mistake lol
Pride in your work is important and why some people have a hard time understanding that baffles me.
I wonder the same thing....

Oh. I forgot. Thank you for teaching the sequence of operation of this unit. That is something that I really want to keep learning.
Great video and admire your work !
Have to mention about safety to work on equipment before turn disconnect off. It should check for grounding as well. I was called to condensing unit for walk in freezer.

This is why you don't just kill the disconnect switch, you kill the breaker at the Panel with a Lock Out-Tag Out as well...

I love the way you explain things
I like putting plastic grommets between the sheet metal if i can. I've seen that problem many times. I've had it rub out inside conduit once. That was a bear to find
Nice troubleshooting! Good job
Thanks bud
Awesome job as always, thank you for taking the time to make these videos!
Thanks for watching

Excellent presentation I love the videos man thank you
Great work, quality repair.
Cord Grips was the word you were looking for. Would have been interesting to see how bad the inside of the contactor was. I don't deal with contactors too much becasue of the HP of motor we deal with but I have seen some pretty bad Size 3, 4 and 5 Starters with contacts totally eaten up or even starters that blew up going phase to phase..
Coil voltage is very important as well most guys install a 24v coil instead of 120 or 208-230v. Awesome video

Young guys. Make sure you check the spade connections at the compressor terminals. Many times, I have found loose connections that make intermittent issues. Most of the time a pair of needle nose can make a tight connection. Also, I like to use dielectric grease on the connectors. It wicks moisture and prevents rust.
This is the perfect situation to explain ferrulls.
was all fuses the same rating in the disconnect? the middle one looked like it was cooking hot too many times, but maybe just different copper blend and manufacture
Excellent video! You are the new Jim Pettinato on youtube!
thanks chris for everything always great video
Hi mate, great video as usual thank you. I have a question regarding the dual port suction service valve you made reference to (21 minute mark). If that valve is front seated and your service gauge was on the port furthest away from the spindle, would you be reading the compressor suction pressure or the suction line pressure. Put another way, does front seating that valve isolate the compressor from the suction line. Many thanks in advance if you get time to answer 👍🏼
lol ive seen that happen about 3 times so far, and once i found several wires or wire, a neutral that was grounding in a freezer evap and fans would keep running because the fan delay cut the neutral off lol, it was odd as i remember disconnecting the neutral and fans keep running lol....fyi do not use safetys or switches in neutral
As far as the condenser fan motor drawing slightly more current isn't a big thing at all. Even if it drew one amp more than normal shouldn't put things in panic mode. If your line voltage was a little lower than normal, the current draw will be higher. Nothing to sweat. If however, the fan was drawing 5 or 6 amp more current, then it's cause for concern. If the bearings were starting to seize, you will have more current draw. Of if the cap is very leaky. When a capacitor becomes very leaky, at that point it turns into a resistor. Great videos. Keep 'em coming :)
Great video. Really explained everything in detail.
When i have a contactor that is "up side down", from how the original one is mounted, i don't EVER install it up side down and just flip the cover. Notice how it is supposed to mount. The top mounting point should be "closed" and the bottom is slotted. It should NEVER be mounted with the slotted side up, for safety. Instead, unscrew the mounting bracket off the back of the contactor and simply turn it around 180° and screw it back on. The contactor will mount correctly and the coil voltage wires will mount in the correct location.
You realize that in order for it to come loose in the upside-down position, one screw would have to come totally out, and the other one loosen, and if it's that bad, the loose one is probably going to fall out anyway.
The margin of safety "lost" by installing it upside down is about 5 percent, and would only cause issues in seriously bad conditions where it's probably the least of your worries lol
Many devices have slots on all positions so they don't even have that slight safety margin.
Now, on some devices it's easy to flip the base, and it's not bad to put the slot at the bottom, but it's not really a serious safety issue.
@@ke6gwf wow! Only 5%? Huh! Where did you find that stat? Did you research that with Underwriter Laboratory? Or did you just make that up to make yourself look smart? But anyway, I was taught to install them a with the slots in the correct postion. You can mount yours any way you choose. Have a nice night.
@@mikec.2746 Thank you for demonstrating the difference between an Installer and a Technician.
You do it a certain way because a person you consider to be smarter than you told you to do it that way.
A Technician looks at a situation and makes their own decisions.
You know what the closed hole is really for? In case you are mounting a new unit, you can drill one hole, put the screw through the mounting hole, and hang it from one screw, while you mark or drill the other holes.
That's why it's centered.
Some contactors and similar devices have them, some have all slots, and some have no slots.
UL doesn't care about slots or holes, and it order for it to matter if the slot is up or down, one screw has to be completely gone, at which point UL and OSHA and IRS and MSHA are totally violated anyway.
Oh, shocker, they can also be mounted sideways! What do you do then?!?
So unless you can show from a manufacturer data sheet, or a code requirement that the slot direction is dictated to be down, than you are just passing on what some individual told you as gospel, and as the only PROPER way to do something.
And if you want to install them that way, great!
And if I am installing one that has a base that easily rotates, I likely will do so if it makes mounting easier, but not all do, and so making it a hard rule doesn't help.
If you had simply said that the bases can often be flipped to keep the slot at the bottom, and it's safer that way, you could benefit the conversation without making any blanket claims that others are doing it wrong.
@@ke6gwf Did you seriously just take a shot at installers???? Just to TRY to make yourself seem superior??? The installers I have ever worked with or employ are top notch people that have nothing but my absolute respect and admiration. How dare you put a group down just to make you feel better about yourself!! You are a real class act.
I do take comfort, however, of never having to know you personally. Especially with your superiority complex. I still can't get over that you would take a shot at people in our industry just to make yourself seem smarter than you really are. You must be a very lonely person. Have a nice life.
@@mikec.2746 Sorry, I was not referring to people who install new units, I was comparing two mind sets.
For instance, in heavy equipment operation, you have "steering wheel holders" and then you have "operators".
They both do the same thing, but one is able to figure out how to do things, the other has to be directed by someone else.
So by "Installer" I mean someone who just installs parts or repeats what they are told by someone else, who isn't able to step back and look at the big picture, or design solutions.
And by "Technician" I mean someone who is able to troubleshoot and design solutions and figure out things on their own, instead of just relying on the directions of others.
One type of person, you have to give them directions on a job, and if they run into anything unexpected, you can expect a call from them needing help to figure out what to do.
The other type, you can send on a job, and you know that they will get the job done, no matter what they run into, because they are able to figure it out.
For instance, if you were using a contactor with a riveted base, and you needed the coil terminals on the other side, what would you do?
Vibration and wires leading to a short. Can that happen? Oh yeah. Good methodical diagnosis. The rust and water in that box looked scary. Going a little heavier on the contactor was a good move. Condensor fan motor looked like it was loaded up with dirt. Always wonderful going in after someone else's work.
I keep tripping too, but like over blades of grass, and pretty much air, can you help?
I enjoy your videos so much. Thanks!

Hi Chris I was watching the tradeshow live stream last night, i am the one starting school soon.
Do you get to work on chillers much? I’m fortunate get to do a little bit of everything. Mostly air con but dabble in coolrooms and freezer rooms aswell
Perhaps a quick topic for a Monday live stream... the difference between solid and stranded wire usage with lugs vs terminals.
I need an office set up like yours...Monday live stream is 👍🏽 for me
also one way to see which is cooler and which is freezer (0:41), is that the freezer has a substationally larger vent opening, because it needs to move away more heat.
"Always leave things easy for the next guy, because the next guy might be you." Works for any trade!
the receiver looked to have slot style packing nut for something like a pin spanner wrench or spanner socket.
probably that way because of total diameter or to keep people from tampering
or a hook spanner wrench, couldn't think of it when I wanted lol.
You checked to see if power was off but where did you put your ground too? Ypu only had the power side probe and not the ground side probe. So where did you have ypur ground touching?
Is there any point in blowing out the dust from these roof units? I'd have thought the motors and contactors would benefit from that
Damn you guys in the states love your wire nuts, they are on pretty everything over there :-) Keep up your good work btw. i love to watch your videos
Again, thank you very very much for your videos. I truly appreciate all the effort you make setting the camera bc it is not easy sometimes. Although, It totally looks like it comes out naturally already. I bet if you go to a job and you don't have your camera in, you fell like missing something haha. Thank you.
Great job again like always

U could do
Voltage drop across the contactor to verify high resistance but i do understand its better then a cal back
Are these units enclosed in the big housing to try and protect the components? Seems like a logical idea to try and maintain the longevity of the equipment.
Thanks a lot for this information, I learned a lot of your vedios and I like the way you explain it
And now the wiring looks fare more "official". If you need to run un-jacketed wiring though a metal clamp short pieces of neoprene hose can come in handy. Snap in plastic bushing for the ends of BX/MX cables and conduits should also be in place, to prevent chafing.
Nice find
NICE VIDEO, GOOD WORK PRACTICES
those cables should have been in a rubber grommet, or a blob of silicone to prevent rubbing. kinda rough. The replacement wiring is soooooooo much better! GG!
When things have to be taken apart multiple times, how do you guys deal with the sheet metal screws stripping out? It seems like after 2 or 3 cycles they don't hold well any more. And on thinner metal, they hardly grip on the first use.
Yeah that happens for sure especially when people use impacts to tighten and loosen them... when it does happen I just go up in size on the screws and hope that they dont continue to strip them...
Go up in size or eventually use a threaded insert and an m8 screw
Good find and nice clean up. I see you have a torque wrist too. ;)
Yep I love my Torque wrist, best money I've ever spent! 😂
"Click"😂
Hi,
How do you think about the wago conectors?
Great job 👍👍👍👍
The handy box had such a high rust line, must of bin a major water source from above. Not just condensation. Do you know?
I love your videos I am gunna be what your doing I love these videos ❤️
Great video !
I hear it's best to replace a breaker after about 4 or 5 trips because they essentially become derated. Also I want some of those insulated screw drivers when I replace wall outlets and such around the house.
What kind of derating are we talking here?
@@thelol1759 In other words tripping at a rating lower than what the breaker is designed too.
SOU6900 no I mean how significant of a derate is it.
@@thelol1759 Not sure. It's been a while since I read this but I think it's some where around 10 or 15%. I'll have to hunt the interweb be certain.
Nice job
You should also ask your self wheres the water coming from, is the pan full, is the compressor over condensing?
How can you tell if a service valve has or doesn't have packing on the stem?
Good video Chris . Can you do more videos on R-290 compressor replacement 🤭😬. I’m getting started on my R-290 kit , want to be ready . Thank Pal .
Thats main!! Learning your sequence of operation!!!! With out that, your completely lost lol Great troubleshooting!!!
Thank you for the great videos. I also like how what I follow on FB will show up here later. Serious question though, are you that concerned on being .1 over amps? To my very limited knowledge, you allow 10% differential when testing electrical.
.1 isn't bad but usually as the motor heats up it will continue to draw higher amps. Also if the capacitor is weak as it weakens further it puts a lot of strain on the windings in motor.
Ted cook says don’t leave crumbs for to talk sh!t.. great advice.
pretty sure it's code to have the evap. fans and condenser on their own circuits and lighting separate also.
then again maybe I have foggy memory
2 things that would increase amp draw on a condenser motor; someone put to aggressive blade on it or if coil is plugging up though your pressures looked good but someone could've tried to increase air flow with more aggressive blade to compensate for plugged condenser coil. ( be surprised how many dirty coils i've come across with that problem; then again maybe you wouldn't)
Plugged coil would actually decrease amp draw.
You know how when you block the air flow through a fan, it speeds up? That's because it takes less energy to swirl air around, then to propel air.
So a dirty coil will reduce air flow through the coil, thus making the fan just swirl air behind the coil, which uses less current.
Now, you are right, they may have put a bigger blade on, which would increase current.
I love your torque wrench click noise you made. How often do you have to recalibrate those hands😁
Excellent!

Do we really need a defrost timer for a walk in fridge, I work on about 7 and if they go bad i rip them out and bypass them never had a problem.
