That sounded like somebody was getting buzzed through the door at the jailhouse. 😆😎👍
I got my veto pro pack LC yesterday . It made the service call a dream to get to tools and see everything easily. I set it up just like yours I was able to pull my field piece probes out, get to my electrical meter and get to my needle nose and anything else I needed. This bag is great .The Milwaukee one was not working for me.
They do make great bags
I have a window unit that does this every now and then. Was curious what would have caused it. Not in the field but I absolutely love the videos, I am always learning from you & some others. Thank you so much for taking the time to video, edit and upload these.
Thanks for watching
Thanks for all the information you give my supervisor came in yesterday and the problem he was describing sounded like the capacitor so he changed it and it worked thanks
Giving the phrase "sounding bad" new meaning; did you call the church to have the last rites administered? 😎
Yeh that sounded rough didn’t it?
Good call
TIME FOR A NEW COMPRESSOR!
Something similar happened to my heat pump. It would buzz like that every 30 seconds or so. It was dimming our neighbors street light 3 houses down. I would have loved to see its amp draw when it was buzzing! Was Surprised it didn’t trip the breaker
Rod is GOING!
Sounds like another compressor replacement 😊
Definitely sounded like it was going to 💥
this sound happened to me, i replaced the fan motor and cleaned the coils and got rid of an unneeded small capacitor and compressor boost and bam worked
The Inrush current has me fascinated
uhoh, BZZZZZZZTTT, the death buzz. if the building dwellers notice the lack of cooling and shut it off right away.? it just may survive, if they don't and it repeats for minutes/hours/days/weeks/months? good chance that it is 100% dead or will fail shortly after repair.
I was sitting here one day and thought what's that weird screaming noise, I heard the echoed off noise for hours that day and didn't recognize it. as I was leaving in the evening, I heard it again and instantly knew what it was, neighbors condenser had an old composite pad sitting on top of it, blocking the air flow, the noise was screaming compressor bypass. it didn't sound that way next door/through windows and fans running, but once exited into driveway to get in vehicle? my ears went started bleeding I hard and spotted the now very clear noise, ran over and uncovered the condenser. that was 3+ years ago.
Thanks for the Video!
Is there any way the Contactor could have been buzzing? Enjoyed watching! 👍🇺🇸
I had two competing captions for the buzz at 0:32!
1. "Ma, food is done!"
2. "WRONG!"
If you hear the Death Buzz, Call Curtis for Prompt and Courteous Service. 😬👍🙏
Nice diag. Seems to be that HP on condenser fans tend to follow a trend when it comes to capacitors. 1/4 HP=5 mfd, 1/3 HP=7.5 mfd, 1/2 HP=7.5 and 3/4 & 1 HP are usually 10 mfd. That CAP did read 10 for the brown wire so likely all was correct with that CAP rating for the condenser..
I liked how it sounds even tho it’s not good haha
Sounds good from my house 👍
that sounded like the russian woodpecker lol it's a jamming signal the russia used back in the day and I think still uses
lol, it sounded like when my son's car threw a rod... 👍
If you get the job cut the compressor case open and show everyone what it looks like inside and what went wrong when the season slows down....
Protech fan motors have the capacitor information on the right side of the motor information above the barcode
Its gonzo. Hope you get the work.
I have had that buzz when the contactor gets stuck halfway confused, usually after a power outage. I just reset the contactor. That compressor did not sound good when it was running though.
That sounds like a locked up compressor to me. $$$
Hi bro from west Alabama
They need one .
that K55HXLRH-0824 motor calls for a 10uf capacitor
I’ve had that happen, turns out they had the wild leg connected to service on the transformer, compressor was running backwards, I reversed it and it was happier , never was quite the same. So I guess my question is , did you make sure it wasn’t running backwards?
Did you change out the compressor? If so, did that fix problem? Update please. Thanks.
I haven’t heard from home owner yet
Change out the video coming soon or compressor lol 👍👍👍
Well what did you do?
So what was the fix? A new compressor?
Great video definitely ready to explode
Yeah, it sounds like it's time to take it out and put It out of its misery! LOL!
What's the number of the large magnetic light that you use?
It’s an M12 rover by Milwaukee
@HVACGUY thanks for replying
what was the problem? Bad compressor?
Compressor is in need of replacing.
Looks like they’ll need a change out .
Curtis in this situation is it more cost effective to change the compressor or the whole outdoor unit ? I guess it depends on how old everything is ?
I would say 10-12 years old. It has a copeland scroll. My ac which would've been 18 this year had a Bristol recip. I think they switched to the copelands around 2010
@@Austin23191I had 3 ruud units from 2008 with Copeland scroll compressor. Those units were POS.
@@CG-1000-Tall the good old Rheem had Copeland scrolls in the 90s.
@@sprockkets I know as I have seen one
Did it have any refrigerant in it?
0:32 Laundry is done!
Just curious, did you have to reverse the wiring in order to get it to run? But definitely sounds like you’re about to have a new compressor change out video coming.
No, just put on that super boost
@@HVACGUY sounds like you have a compressor change out vid coming soon?
@@HVACGUYyou left it running with the boost while you can hear the mechanical issues going on?? I wouldn’t have left it running like that.
@@mwatkins2464 things already shot, not much more damage can be done. the compressor will open if it over heats and protect anything else.
Sounds like the compressor is going out
I did not see what brand this was? However, I like how the capacitor is located on this brand and I assume this helps to keep it cooler and it should last longer by being cooled?
Do you have any knowledge if this make the capacitor last longer? It just amazes me that capacitors only last about 2 years before exploding. (I am not a hvac technician.)
Most capacitors last longer than 2 years. They do go bad but not to that extent. You will always have something tear up on anything but for the most part they do last unless they are China or Mexico made
SOUNDS LIKE COMPRESSOR WAS RUNNING IN REVERSE.
id also disconnect the fan motor while testing *
I didn’t see you measure the load voltage on the contactor, did you verify you had adequate voltage
Especially with that FP fused disconnect. You could have loose connections..
loose connections at the disconnect aluminum connectors, corrosion due to lack of anti oxident paste, contactor pitting, really need to measure and not assume voltage is adequate
Regardless that's a freakin mechanical failure inside the compressor
One of the downsides of a Copeland Scroll is they don't have an oil pump.
When a compressor is running backwards it can sound like that.
Compressor go fubar
you dont show the fix?! you just leave it at that ?
The next question will be what else may be wrong. Put a new compressor in and find a bad TXV, dirty evaporator, low charge, etc. Likely something caused the failure not just age.
I suspect there’s out of acceptable voltage drops and spikes from the transformer feeding the main to house.
I have a neighbor in my rural area that was having same issues and it was the transformer at the pole wiping out his appliances.
Possibly but I don’t see that much for compressors failure on single phase. That will take out cheap capacitors though. I’m thinking something else will be wrong.
Pretty sure that motor is a 10uF
HVAC work is like 49% changing capacitors, 49% cleaning coils and filters and like 2% actual hard technical troubleshooting
Don’t forget clearing blocked condensate drains !
Sure it is, until it isn't. Then you get to earn your keep.
Unless you're in commercial
Yea well why don’t you start fixing your own. You won’t last. It takes 2 years to learn the basics then on job learning starts but your so smart you don’t have to know all the other stuff. Do you get what I’m saying, about you. It’s not good
You left out the 30% that is cleaning the drain line !
Idea: are the compressor connectors all the same, or maybe a couple different ones? They all seem to look the same on your videos and if so... why dont you make yourself a plug from an old harness from one and have it be like 3 feet long or something with regular spade terminals on the other end of the wires and you can use it to easily reach down and unplug the harness, plug your test pigtail into the conpressor and quickly and comfortably do your checks?
I was thinking the same thing. It's called a breakout box.
@jw33 yeah, I see him struggling to get a good connection and accurate readings all the time. This will definitely speed up that process
I asked the same question a while back 🤷♂️
It's logical to think that ohming out compressors that way with a pigtail harness, but that extra 3+ feet of wire can give a slightly higher resistance reading than what is actually in the windings themselves, by going directly to the pins you're ohming out the windings directly at there actual lenght on the stators w/o adding addtional to it. Take note when watching most HVAC techs you almost never see them ohm out compressor windings using the harness wiring in the unit, even if it's fully disconnected from the cap and contactors. If a winding is supposed to be 1.2 ohms for example per the mfg, but the actual readout at the pins is 0.7 ohms, you add a short length of pigtail and not realizing it, that pigtail has say 0.3 ohms, you're goign to be like, no problem, it's within tolerance, but in reality it's below the minimum threshold.
@fldave612 true, to eliminate that you can check the value of the harness each time prior to using it just like checking your leads on your meter before testing resistance by putting the ends of the leads together and making sure is 0.00 ohms, just make sure the harness is the same each time as one process
Bet that thing could fly to africa and back
Doing half the fix is a video?
Internal failure
Wait a second, you never once checked if the system had any refrigerant in the system! That is exactly what a compressor sounds like with no refrigerant. If you didn't gauge up, how could you possibly know? Did you quote them a new condenser, compressor or full change-out? The capacitor was good, the readings across the compressor terminals were nearly dead on. Are you sure there isn't a leak that vented all the refrigerant or a majority of it out? I have seen this more than once in my career.
Did you get your training from RUclips? 😂😂😂 Clearly that's a doa compressor
@@totallynotbreezytheboss7218 That's funny all things considered. DOA is dead on arrival, I suppose it might have been. At the end of the day, a empty compressor sounds like marbles bouncing around. I bet that compressor was flat and empty based on the readings taken across the compressor terminals. I have seen it before, so without checking it, it is just guessing. So did he sell them a new condenser or a full system?
You won't have a high amp draw like that with no refrigerant.
@@Bryan-Hensley Of course you will have high amp draw on a compressor that is struggling because of a lack of refrigerant. Does it just give up and stop working? No, it works harder and the amps skyrocket.
@@Balticblue93 no it doesn't. No load on the compressor. less amp..
Sounds like its out of refrigerant
that sound= compressor let go= $$$$$$$$$$ out of your piggy Bank better hope thy have the Money to get it replaced
Didn't think the capacitor. Normally these sounds on electric motors = loose motor core.... (few times in my life, EE degree was useful, lol). Check compressor oil, most likely - will be changeout.
There’s no way to check the oil without draining it all and measuring. Did you hear it once I got it started?
@@HVACGUY Sounds like vertical shaft wabbles and the core touches something....
@@HVACGUY If this were me, I would ballpark estimate that cap to be 45/5, maybe 45/7.5. I duno how old this thing is, but that looked like one of the old indestructible plastic housing capacitors. And while we do trust them, I just can't see one that over spec still being in service.
Just another hack with fancy tools
Yep, just another hack, LOL bet you would call this hack if you needed him.
Just plain Ignorance on your part.
