my carrier unit keeps tripping breaker for air handler only?
I woke up last night to a freezing house. The t stat was blank. went outside flipped breaker and it went to emergency heat, which tripped breaker after 2 min. The compressor and fan came on when i press contactor on condensor. So what is the most likely reaon. red wire from t stat is sendin 24 volts to outside unit and to tstat.
its a electric unit has a air handler inside. i checked heat strips none were broke and had 120 going to each. And breakers are like 2 years old at that so i dont think its that either. I have voltage going to capacitors and to and from contactors
I just took board out of air handler and it has burnt thin a magger lol underr5 part of board so im guessing thats the problem
Humm, What size AMP breaker do you have on the furnace? Sounds like you either have a bad breaker or they are under rated for the application. What KW heat package do you have for the electric back up heat? Your problem is either at the breaker for the furnace or the blower motor.
I think you have a breaker issue, possibly the fan motor armatures are bad which will cause excessive amp dram and trip the breaker, even though the fan might still be working.
