What is that law that says if something breaks, it's going to happen when you need it most? It was 101 degrees here in VA yesterday, and I started having issues with my outdoor Goodman GSH13 heat pump. My house was getting warm, went outside, and realized the HP was off. Checked the breaker, it was tripped, so I reset it. Checked the fuses in the disconnect, and one was blown. Replaced it, started the unit, and got the familiar buzz when the unit is getting power but nothing is running. Compressor WAS running, condenser fan was not. Tried to spin the condenser fan with a stick, and would not catch. I turned the unit off, and let it sit like that overnight.
This morning I went out, flipped the disconnect on, same thing happened, except the compressor stopped trying to run after about a second or two. After the compressor stopped running, I WAS able to manually get the condenser fan to run full speed. When the compressor tried to kick in (about every 2 or 3 minutes), I measured voltage coming into the unit, and it had dropped to around113 Volts (from 120). So it seems that the compressor is certainly trying to draw sufficient current, something just isn't working.
Is this a symptom of a bad capacitor (not providing enough juice for BOTH compressor and fan to run), or is a failing compressor more likely?
Thanks for any advice!
