I have a Mastertemp 400 that is not igniting. At startup the blower does not turn on. No errors on LED Panel or on board. No lights on ICM.
I direct wired the blower to ICM and the blower does power up, but still no ignition.
The article I was following stated if blower works with direct wiring, then the issues is either bad ICM or bad control board. Anyone know how I can test to figure out if my problem is the ICM or the Control board?
