York H2RA036S06E AC triping breaker

I have a York H2RA036S06E unit that stop cooling, I went outside to check if the fan was working and it wasn't. checked the breaker box and the breaker that provides power to the condenser was tripped, and it won't reset unless I remove the compressor plug. With compressor plug removed the fan works fine, line voltage at the conector box and on the now disconnected plug going to the compressor is 120v on the red and black lines.

The Compressor model No. is H2RA036S06E by Bristol and the star and run capacitor is 47/5. the capacitor measures 37 ufd on one lead and 5ufd on the other measured from the common lead. which is I believe in tolerance.

Ohmeter reading to the compressor terminals from ground (taken from copper line) is as follows:
Common lead reads 2.1 ohms
Star lead reads 1.8 ohms
Run lead reads 1.3 ohms

Ohmeter readings from the compressor from:
Common to Stars is 3.3 ohms
Common to Run is 3.3 ohms
Run to Star is 3.1 ohms.

As I understand on a good compressor the resistance to ground on this terminals should be infinity or very high.
Is this true for all compressors? and is this one is definitely bad please help. it will save me the $100 service call.

Welcome to the forums.

Ohmeter reading to the compressor terminals from ground (taken from copper line) is as follows:
Common lead reads 2.1 ohms
Star lead reads 1.8 ohms
Run lead reads 1.3 ohms
If all wiring to the compressor was disconnected and any terminal showed resistance to ground.... that would mean a shorted winding.

AKA.... compressor is no good.

Thanks for the quick reply, I'll be shopping for a new compressor or a new condenser now.

Here is the potential problem n cheap solution

Your contact relay (contactor) in the outside fan unit may be busted. It costs $19 on eBay and the part number is on the relay. Mine is 024-27531-000.

The compressor is shot. Unless it's < 10 years old, time for a new condenser and matching indoor coil.

For one thing; the compressor Run capacitor tested bad & would have to be replaced. Never heard of a run cap being rated 47-MFD.

Compressor windings appear to be grounded, so compressor is shot.
