Yep , sometimes you have to wait until next day to be sure

 

X2. If you are in a restaurant with an ice machine sometimes you can speed it up. C02 fire extinguisher? Overnight is best.

 

I have gone to a gas station and gotten a bag of ice to put on top of the compressor .

On the tag of the compressor many times it gives the time in minutes that it takes the overload to close. I don't know at what ambient they base the time at.

 

Next time ( if the compressor is in the airstream ) disconnect the compressor from the contactor and capacitor and turn on the unit letting the condenser fan pull the outdoor air across the compressor hook up your ohms meter and monitor. Certainly if it does not close in the time your there then check the following day . You can also disconnect the blower relay if you do not want to circulate air downstairs.

 

Hit it with a dead blow

 

Right on tap it with a hammer, check ohms again. Resets them a lot of times

 

If there is a hose nearby, run it on the compressor. I've found that usually does the trick within a few minutes. If not it could take a couple of hours or possibly over night. But by all means never condemn a hot compressor. It will cool down and almost definitely run again.

 

+1 cold water

 

Put meter on tone and run the hose.

 

I have found that putting a bag of ice on top of the compressor can have a very positive effect.

Great minds. Have you tried a C)@ fire extinguisher?

 

Hopefully it will close, then to figure out why it was open. Good luck

 

Back in the good old days we would just turn a bottle of 22 upside down on them

 

And make mustard gas. Might get away with it on a roof but still risky.

 

This a single phase compressor? I thought on single phase start to run should always have resistance, but anything to common should be open as the switch breaks common...I am not 100% sure, just mention it because I waited overnight and came back to find it still didn't start..

 

Probably not out on overload then.

 

I had one that I hosed for 25-30 min. until it was cool to the touch. The overload would not reset. I hit it with dead blow. No reset. I told homeowner I'd return the next day and test again before condemning the compressor. Next day. It had reset. Sometime that internal heat in the windings can take a while to cool down.

 

Been there done that.

 

water hose on top of compressor and add refrig.

 

they should not all be open.

 

YUP.
R-S should be conductive.Single phase is C-Thermal o'load protected.

 

Only if it's "burnt" and you open it up.:stinks:

 

I flipped the breaker off on one last night at 11 PM. I think the condenser fan went, I will know more today. But how much damage has the heat done to the compressor? I will probably recommend a new condenser if that is the case.

 

Anytime you have a comp cycling on internal o'load it's not good but that is why they have them. If it's just a "short" time there is generally not a problem and "most" go on for a long life.When you get it back running,smell the gas or do an acid test and that will give you an idea.Yeah I know,Saftey first but I'm old and know when to stop.:grin2:

 

Old. you? In any event I went back this am and turned on the breaker. Condenser fan didn't turn, compressor didn't start and cutout on thermo disk. Label on top is pretty much burned.

 

Most overloads never even get used , but the ones as mentioned above, were never designed to be operating controls.

 

FUBAR.
Sell 'em a new one.
Not "that" old,58,mater a fact but old enough to know & too old to fight.
Like Hank Jr. said, Hangover's hurt more than they use too....

 

I am a bit older. They are getting a new condensing unit. Too bad I ill have to take the compressor off of it to get the dang thing up on the side of the building. Pretty much quit drinking 30 or 40 years ago. Haven't had a hangover since.

 

Me to.20 yrs now.Figure of speech about getting old.
We had a HP pkg unit change out a week ago on a Dr's farm residence behind some "fancy" shrubbery and were "expected" to lift it over them.
Mexican hired hand was cutting back the crepe mertyl's and I went over to him and asked if they had a tractor with a front end loader.Yes.Strap's?Yes. Come on and get it.The rest of the day was exceptional.
