When ever I drink I get to the point where I miss the little details. Thanks for looking out on that rotation thing I am sorry I missed that one to much Jack!!!!
Thank you for taking the time to record these videos. I can never thank you enough. Being able to see a Pro working in real time has given me an immense amount of knowledge. Pressure and temperature is important for us to see when you work on any unit. you take time to show us every little detail.
Great Work Jim! If you put the amp meter on the start capacitor lead you can tell it the relay is working, once it switches the start cap out of circuit the amps should drop to 0
It was a great video for my students to see the importance of "paying attention to detail" (catching the fan blade rotating the wrong way). As always good job Jim. Woody
another good video thanks Jim I learn a lot watching your videos keep making more one day I will run into you someday at a supply house I work for local hvac company.
jim you are awesome you just remind me my ex boss I was his assistant for 12 years ...he is now retire..he worked just like you...I like the old school
Hi Jim ; I am 60 years old so my knees hurt me very much when repairing AC so I brought me a small low folding chair to use on sight I would recommend it for you very much .
First no cool of the season had a bad contactor and found a non reversible condenser fan running backwards. I owe my attention toy detail to guys like you.
I have that same amprobe meter too. It's a good meter for the cost and Amprobe is owned by Fluke. I just got a Flir CM174 (clamp meter with thermal imager to insoect electrical connections and any over heating connections. Flir sold it to me for $150 as a sorry/olive branch from multiple failures to fix a warranty claim on another tool that they sent me a new updated Imager! I'm still testing the meters operation, accuracy, and functions before I trust using it.. (extech makes the Flir meters since Flir owns Extech). Also, (just a comment on another one of their test instruments) flir's non contact voltage detector is the best I've used to this day! I highly recommend it over Fluke, Klien, Greenlee, ect non contact voltage detector.. it has two sensitivity setting for high and low voltage that work phenomenal. SORRY FOR GETTING OFF TOPIC, but I'm a extreme Tool adddict!
Hey, great work. I thought that fan motor looked unusual when I saw it running towards the beginning of the video. I also hate how the fan motor run cap was installed with electrical tape covering the connections and the lack of a strap...it makes working on equipment just that more difficult to sort through. I keep a roll of perfected metal strapping for replacement caps. Also, that older low pressure switch may have previously been opening because the suction line drier had pressure drop across it....and the reversed fan motor caused higher head, & possibly suction pressure. You ever know what the previous clown working on the unit may have done to the unit. I find loads of equipment with suction line driers that weren't removed after three days to a week. A trick I learned from a factory engineer is installing two valves and bypass piping around the suction line drier to remove it from the circuit after its usefulness has been reached. It save the tech and owner money in the long run.. not to mention destroying a new compressor because of severe pressure drop from the HH drier. I had a failed closed potential start cap relay take a compressor out that was only 6 years old. The system had regular bi-annual maintenace since it's install as well....it was a Bristol two stage compressor..JUNK!! I'm glad your a meticulous tech, just like myself, and insist on doing the job right. Just explaining to the owner to agree to perform the work is the only road block that would hamper my work ethic..that's why I document EVERYTHING. (And always take pictures just to CYA..before and after the work) It would embrass me a lot if I did crap job like the previous tech that worked on the unit. I wish I had a quality, easy to use, small camera and know how to make videos!
Just goes to show years of experience means you would catch something that most young people with little experience normally would blow by them Great job on video Jim
Failed starting on a compressor, use a hard-start-kit or a compressor saver, with run cap if needed. Takes only a few minutes after ohming out the compressor between windings and ground. If it starts, bad start components, if it doesn't, locked rotor. Would have saved you an hour or more. If bad start components, change them all, but if they've failed/burn't, then your compressor is on its last legs, more than likely. Good call on the fan running backwards! Could have damaged the compressor and caused the whole thing.
Jim start capacitors come with bleed resistor. If the resistor is left in line, the capacitor checker will incorrectly read a much higher value than rated capacitance.
good catch on a fan, which could cause another comp. to go, thanks for the video, i been checking your channel few times a week for the new vids, please keep them coming if you can thanks!
The relay switches the start capacitor out of the circuit ? Is the start winding also switched off ? What controls the relay ? Does it also have a run capacitor ? Thanks , :-) Wyr God bless
Hey Jim- What made you suspect the bad relay? Im somewhat new to the commercial industry and would never have thought to check that relay after getting a high amp draw, I would have thought the compressor had a locked rotor. Ive never seen this problem before, that I know of anyway.-- Thanks Jim
hello jim, ran into this problem today, and am curious as to what number you touched with the start cap 2 or 1? thanks for all your vids!!!! hope your well and happy!!!!
Jim had that unit not been marked with what refrigerant it was in it how would you determine what it was if it needed some, or would you just recover the unknown gas and replace it with a fresh charge and mark it?
heya im from south Africa iv got a freezer room with x3 blowers in the right side one is icing up on the coil i checked the defrost heaters they are working fine what could cause the coil to ice up ? the temp the customer is looking for is -20 but its running on -8 to -10
The relay switches the start capacitor out of the circuit ? Is the start winding also switched off ? What controls the relay ? Does it also have a run capacitor
I'm hoping the guy who made this video is not upset at our detailed explanation of his work. I'm sure he is well aware of what we spoke about and I was certainly joking about him being senile. Matter of fact, he is one of the sharpest hvac guys I have listened to. Job well done Mr. Pettinato. Job well done and thanks for taking the time to educate the younger guys who do this work.
+Luther Fairley the relay was keeping the compressor's run winding in the circuit, it draws high amps, it should only be engaged for a second, then drop out, it's like trying to drive your car down the throughway in first gear.

Great Work Jim! If you put the amp meter on the start capacitor lead you can tell it the relay is working, once it switches the start cap out of circuit the amps should drop to 0
It would be nice to knew too the amps difference with the start + run capacitors (stuck relay) & without start capacitor (only run capacitor).
It was a great video for my students to see the importance of "paying attention to detail" (catching the fan blade rotating the wrong way). As always good job Jim. Woody
that was funny, that fan running backwards . i find so many of those too. usually on 9w motors on small condensers. blades put on backwards.
+OcRefrigeration & H.v.a.c. right, thanks
just goes to show ya...Always check the basics.Never assume..Jim, you are top notch buddy.
Great work Jim always learn something
Nice work, Jim. Thanks for posting.
check between contacts 1 & 2 to see if contacts are closed.Just another way.Great vid Jim.
Thanks, I'm Jim always learning something new from you.
+Ramone Duval thanks for the comment
another good video thanks Jim I learn a lot watching your videos keep making more one day I will run into you someday at a supply house I work for local hvac company.
+james rook sure
as always another great video Jim- thanks alot
jim you are awesome you just remind me my ex boss I was his assistant for 12 years ...he is now retire..he worked just like you...I like the old school
thanks for informion and good repering and good ingnering
SUPER HARD WORKING TECH!!!!!
Now that's a waker upper on Saturday. . Good repair Jim.
+A&J Heating got to be somewheres, might as well be making money, thanks
Hi Jim ; I am 60 years old so my knees hurt me very much when repairing AC so I brought me a small low folding chair to use on sight I would recommend it for you very much .
+salehhamid mine hurt too, I'm 65. I got two foam pads, that I can double up, it's real cushy, thanks

nice work Jim,Thanks., I had to chuckle when you said the condenser coil wasnt to dirty,

i am a A/C Student at APEX. I have learn a lot fro your videos.
I'm thinking about making the plunge into HVAC in the Vegas area. I've been in retail for 15 years and I just know the malls are going to close.
great video, I see your boots are showing miles already!
Just goes to show years of experience means you would catch something that most young people with little experience normally would blow by them Great job on video Jim
+hardcooling thanks

That was kind of ancient looking. Great video, Jim.

+hannarye It was an old Bohn condensing unit, it was ok , the wires were a little congested, thanks

Good video! Yea, that hot start cap was the sign. staying in the circuit.
+OcRefrigeration & H.v.a.c. thanks
I saw a couple of Allied Refrigeration guys in my area about a month and a half or so ago. Working at one of the Circle Ks here in Bowling Green OH
+Cory Farren thats another company, Allied Restaurant repair, they market all the chains and hire alot of young guys.
Great work Jim
+Harry Dickson thanks
Another great video on how to do refrigeration service the RIGHT way!
nice work Jim. R408A is the substitute for R502.
Great Video. THX.
Jim start capacitors come with bleed resistor. If the resistor is left in line, the capacitor checker will incorrectly read a much higher value than rated capacitance.
Nice Job Jim, Your right what a mess, Hope whoever worked on that last, Dose not move to MN.
+Arnie Grote he retired, thanks
good catch on a fan, which could cause another comp. to go,
thanks for the video, i been checking your channel few times a week for the new vids, please keep them coming if you can thanks!
+Dennis Noone thanks
Well Done has always. Jim
+Bobby Tectalabyss thanks
The relay switches the start capacitor out of the circuit ? Is the start winding also switched off ?
What controls the relay ?
Does it also have a run capacitor ?
Thanks , :-)
Wyr
God bless
Back emf controls the relay once start cap is pulled out of the phase of the motor or compressor.
Jim, I'm your fan! Don't stop shooting, please.
Hey Jim- What made you suspect the bad relay? Im somewhat new to the commercial industry and would never have thought to check that relay after getting a high amp draw, I would have thought the compressor had a locked rotor. Ive never seen this problem before, that I know of anyway.-- Thanks Jim
you make awesome videos
Wow my neighborhood. Sandusky
Nice repair. When you do the rest video it please.
+Rob HVAC I'll do it just for you Rob, thanks
Thanks *****
hello jim, ran into this problem today, and am curious as to what number you touched with the start cap 2 or 1? thanks for all your vids!!!! hope your well and happy!!!!
haha wow the fan rotation lol
+Holydany yeah, that was a surprise, thanks
You are the first hvac guy I have seen on RUclips discharge a capacitor before checking it. One guy uses his finger, we know who.
Nice Job Jim
+Gabriel Bumbar thanks
Hey Jim, Just curious why would you change gases if you weren't doing a major repair?
If he had to add refrigerant, which I think he said it was low at the beginning, he's not sure of the status of the 408. May be obsolete.
Jim had that unit not been marked with what refrigerant it was in it how would you determine what it was if it needed some, or would you just recover the unknown gas and replace it with a fresh charge and mark it?
Great Troubleshooting Jim especially on that condenser fan motor. How's new Klein plier work for you.
+Lu Wang I like them, they are hefty, thanks
and again, you went beyond my HVAC knowledge. LOL theres nobody else on youtube that makes me feel more stupid. LOL
+jeff leonard thanks
Sounds like a Turbo whistling when you were driving, does your van have the Duramax in it?
heya im from south Africa iv got a freezer room with x3 blowers in the right side one is icing up on the coil i checked the defrost heaters they are working fine what could cause the coil to ice up ? the temp the customer is looking for is -20 but its running on -8 to -10
+Davynn Steyn possibly the expansion valve is out of adjustment on that evaporator.

I think you should have retested it with the original relay after fixing the loose wire. Maybe it wasn't bad at all...
He did. Thats what he did by touching the wire to the relay and then removing it quickly.
A loose wire would have caused the start cap NOT to engage on start. The relay was stuck closed and therefore the start cap was always in circuit.
So Jim the relay is bad I understand that, but was the unit going out on overload because the relay wouldn't shut the unit off?
+Luther Fairley the relay was keeping the compressor's run winding in the circuit, it draws high amps, it should only be engaged for a second, then drop out, it's like trying to drive your car down the throughway in first gear.
+Jim Pettinato thanks! Jim I'm very new to the trade...I love your channel & I also love how you explain everything! Please keep the videos coming
The mechanical pressure switches are junk as well.
