Home furnace not lighting off.
Have a residential G6RA Series 80+ furnace/Air Conditioner.
When it starts its cycle, the ignitor never starts glowing. I can hear it going through the cycle but then it finally stops and the red LED on the circuit board starts flashing 4 times.
The furnace booklet says 4 flashes means "Ignition failure (Check Ground)"
Do you think having the ignitor replaced will do the job?
