Unit wasn't working. Contractor came over and replaced 30 AMP fuse and charged me $125, $42 for the fuse alone. What a joke. I paid because of bitch reasoning, in other words I have something to complain about to the contractor when I go to kill him tomorrow.
So now to the real question. Pressure and temperature are good. Compressor is fine. When the unit "spins" everything gets cool. But the unit after working for a couple hours, turns off. Now once I turned the breakers off and restarted and all was OK for about 4 hours. Then unit shut off again. I can't keep on playing with the breakers, and don't want to for the unit's sake.
Had contractor tell me compressor is fine and freon level is good. What could be wrong with the thing? - Thanks!
P.S. It is not something simple and I deem it to be something electrical. And yes, I can use a thermostat, even if it is programmable. I did graduate in Engineering, but that only qualifies me to be an idiot when it comes to servicing HVAC equipment. Thank god I sell mortgages now...
Carrier's Web Site sux, and I can't find needed troubleshooting manuals. Be that as it may, I don't want to take on the project anyway, because supposedly I have a 10 year parts and labor warranty on all my Carrier equipment; another thing I will bitch about tomorrow.
