Carrier Weathermaker 9200 problem
I have a little problem. It happen about every three days or a week. My furnace will try to come on . Meaning that the draft induction motor will start, run about 10 to 15 seconds then cut off. About 20 or 30 seconds it will try again and do ok. Sometimes it does not try again. I have at first thought it was the thermstat because you could just tap on it and then it would go ahead and work then i found a loose wire at the control board on the furnace and thought that this was the problem but now i am still having problems. Somestimes when it is calling for heat and nothing is working i go to the furnace and just the bump of removing the cover will start the draft induction motor and again somestimes i can just bump the furnace and it will start. Sometimes i can just turn off the power and back on again and the blower motor will come on and run for about a minute and then the draft motor will come on and the furnace will light and work ok for days. what could be wrong now?
