Last week I was walking around the building with my IR temp gun checking supply temps when I discovered a system not cooling. Blower is running so I go outside and check the outdoor unit. It is the carrier listed above. I remove the panel and find the 77a internal breaker tripped. I reset it and the cond. fan started to run for a few seconds before it tripped again. I didn't have time to check it then, so I killed the disconnect and put the panel back on.
This morning I had time to check it out. I opened it back up suspecting a bad compressor. I connected my amp clamp, turned the disconnect back on and waited for time delay. When it tried to start I was reading 117a on the motor but it didn't sound like it was turning. After a few seconds the breaker tripped. I repeated this a couple times checking amps on the other 2 motor legs. I believe they read 102 and 91.
I killed the power and opened the terminal box at the compressor and ohmed the windings. All 3 read .4 ohms with no short to ground. Seems a little low to me but I didn't check specs. They did all read the same.
I am ready to condemn the compressor, but maybe I am missing something. Also, the oil eye is BLACK.
