I have a Nordyne furnace that is trying to ignite. It goes through start cycle but igniter doesn't glow. Makes three attempts then faults, sending fault code "4 blinks of red light.
What is fault?

The fault codes should be written on the inside of the door panel . Tell what each code means
Is probably going to say replace igniter

I agree with previous poster I might add that the ignitor can be visually diagnosed usually, is it cracked or grey anywhere? Or part missing? Ohm iyt out for continuity, and test for 120v after initiating a heast mode and inducer fans on about 30 seconds a click will alert you to test the leads to the ignitor.
