Thanks. Will replace and report.
Bad news for me. Replaced the Thermostat wire to the outside unit and the fuse blew when I tried to start the AC. I know its not the wire because I first tried the AC without power to the outside unit and all was okay. I then raised the Temp on the thermostat, went out and powered the outside unit and when I lowered the temp on the thermostat so the AC would kick in, nothing happened. Went to check the fuse and it was blown.
Last year, I replaced the contactor on the outside unit because it got stuck and the compressor would not shut down. But since the fuse blew when the contactor had 110 volt and not when the breaker was off, I'm assuming the contactor is bad. Is there any test that can be performed on the contactor with a meter? Thanks.
The out door relay will snap closed Werther you have the power on to the outdoor unit or not. Are you sure you don't have a line volt wire touching low volt in the out door unit. With the stat not calling for cooling, turn power to out door unit. then check low volt wires to cabinet ground and see if you have any voltage. If you have a bad contact in the relay, the relay can chatter real fast and that would increase the amps fast and blow the fuse.
Check all wire connections on the relay to make sure they are tight, and check the contacts of burned points. Paul
