Worked all winter to heat the house (heat pump) although I was rather expensive, $250 bills vs $60-$70 without it running the last couple months. Anyway, I tried to start it to cool since its raining is very humid and it wouldn't run so...>Inside unit was running, blowing air, sending 24v signal >Confirmed capacitor was good >Confirmed the 240v (Had to replace breaker in main panel, it was kinda working kinda not.)>Fan on outside unit would turn on but not compressor >Replaced contractor even though it seemed good >Fan will run but compressor just hums and tries to trips the breaker >Replace capacitor >Breaker trips immediately So, all I can figure is the compressor is locked down? Worth trying a hard start kit or do I need to look into some window shakers? Or $125 to have a "pro" come out, tell me what I already know and try to sell me a new system.
>>2992977It might be the compressor, but you should check the disconnects at the compressor (under the square black cup) for arcing, carbon deposits, and corrosion/oxidation. Maybe you just need to clean or crimp new disconnect terminals.
>>2992992>clean or crimp new disconnect terminalsIf this is the problem, use a thin (THIN) coating of dielectric grease on the compressor pins and disconnect terminals to prevent it from happening again.
>>2992977Unless you fucked up the wiring in the contactor or capacitor it sounds like the compressor is seized. You could try a hard start kit but most likely you'll need to change the compressor. Breaker would trip right away if the windings were shorted to ground. If it hums a bit before tripping it's a mechanical failure most likely
>>2992977> $250 bills vs $60-$70are you sure the compressor was running in the winter? if you have emergency heat backup, it might have been locked up all winter and instead running on emergency heat.
>>2993088I could hear it running.
