Carrier Gas Furnace, Model# 396GAW000075ACAA
This morning awoke to no heat. All was working fine the day previously. Checked thermostat and it appears okay. Checked all the breakers and they are all fine. The circuit board was replaced just 4 years ago. I opened the top part of the furnace and checked to make sure the fan was free spinning and it was (my neighbor had their motor seize up last year). When I pushed on the door power switch, I can hear the relay on the circuit board clicking. The blower motor sometimes makes noises like its trying to start, the fan will spin very slowly and then stop. Other times, nothing happens. In either case, all I hear is a low buzzing noise coming from the motor.
If it is the motor, where might I be able to find a suitable replacement? Do I have to pull it out to get the appropriate part number?
Thank you very much.
