Draft Inducer Motor

Hello everyone,
The draft inducer motor in my gas furnace come on intermittantly. When it fails, the heater won't light. As a result, I don't get much heat. Does anybody know why it would do this?
Thanks
Tom

Start by measuring the AC voltage being supplied to the inducer motor. If it's steady at 120VAC and the inducer motor doesn't run reliably, you need a new inducer motor.

If the voltage supply to the inducer motor is erratic but the 24 VAC power supply to the circuit board is steady and the thermostat is steadily calling for heat, you probably need a new circuit board.
