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.

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.

@Garth2011 Год назад

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..

@natersalad889 Год назад

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?

@jw33 Год назад

I was thinking the same thing. It's called a breakout box.

@natersalad889 Год назад

@jw33 yeah, I see him struggling to get a good connection and accurate readings all the time. This will definitely speed up that process

@chuckquinn8026 Год назад

I asked the same question a while back 🤷‍♂️

@fldave612 Год назад

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.

@natersalad889 Год назад

@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

@Aerospace_EdC Год назад

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 ?

@Austin23191 Год назад

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

@DRNEGOLICIS Год назад

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?

@ronroberts7566 Год назад

I didn’t see you measure the load voltage on the contactor, did you verify you had adequate voltage

@Metal3983 Год назад

Especially with that FP fused disconnect. You could have loose connections..

@ronroberts7566 Год назад

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

@totallynotbreezytheboss7218 Год назад

Regardless that's a freakin mechanical failure inside the compressor

@Chris2745100 Год назад

When a compressor is running backwards it can sound like that.

@hvactech77 Год назад

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.

@BrokenRRT Год назад

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.

@hvactech77 Год назад

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.

@tieron426 Год назад

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.)

@mwatkins2464 Год назад

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

@Balticblue93 Год назад

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.

@totallynotbreezytheboss7218 Год назад

Did you get your training from RU-vid? 😂😂😂 Clearly that's a doa compressor

@Balticblue93 Год назад

@@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?
