My ac won't turn on at all
I purchased a brand new central ac unit and it worked last year fine. This year I tried to start it and it went on for 30 sec and shut off. I tried everything from checking breakers to buying a new thermostat. The fan won't come on by itself either. I checked the 24v at the main contactor and it's not there. I pushed the center of the contactor in and the unit worked fine,just compressor and fan came on but not sure of the air handler, it is in the attic the switch is on. I think the problem is in the handler but I am not sure how to check that. Please help me its gitting real hot.
