I have a Trane 1200 XE that I replaced the Compressor two years ago when the crankcase heater wire shorted it out. It has worked fine until recently when I turned on the AC and it ran for about 20 secs. then tripped the breaker. It does this both in AC and Heat setting. Bad Breaker? or possibly not coming out of start mode. Need a little direction. I am a Lineman by Trade.
