The problem is more than likely not your board. It’s the inducer motor, more specifically the start/run capacitor. Try removing the capacitor, shorting it out across both terminals and then making sure the resistance is within tolerance. If not replace the capacitor.
How do I know if my inducer motor is bad?
One of the first indications of a bad draft inducer motor is likely to be the sound it makes. A failing inducer motor may create a noise shortly after a heating cycle begins. This could be a tapping noise, or a humming or whirring sound.
What happens when inducer motor fails?
If the inducer motor doesn’t turn on when it’s supposed to, the furnace will recognize this and shut down. It will wait a bit and try again. If the motor doesn’t start after 3 to 5 tries, the control board will stop sending voltage to the inducer motor, and essentially locking it out from attempting it anymore.

How do you bypass an inducer motor?
Quote from the video:
Quote from Youtube video: So this is the wrong way to bypass a pressure switch. The right way is to have the inducer motor turn on first and then bypass the pressure switch.
How much does it cost to replace an inducer motor?
Your furnace’s draft inducer motor removes toxic gases like carbon monoxide from the heat exchanger. The average cost to repair or replace a draft inducer motor is $200–$1,500.
How long does an inducer motor last?
12-15 years
Furnace inducer motors can have a life expectancy of 12-15 years. A replacement furnace inducer motor can cost around $800.
Does an inducer motor have a capacitor?
The capacitor is what helps supply power to the motor when it’s first starting up. If it can’t hold a store (or charge) of electricity, or enough charge it simply can’t do it’s job. The result is not enough juice makes it to the inducer motor, and it most likely won’t start up.
Why am I not getting power to my inducer motor?
If the draft inducer does not start then you probably either have a thermostat , thermostat wiring problem, electrical problem, control board problem or a bad draft inducer. 2. Tape the blower door safety switch shut (if equipped) and set your thermostat so it is calling for heat.
Can you oil an inducer motor?
