Hello !
I am an auto mechanic, so when it comes to furnaces, I know nothing, but I have been learning about my furnce today.
I have a goodman GMP-150-5 furnace that when the thermostat turns it on, I haer the draft fan start and run and after about 5 minutes, it just shuts down.
Now, I looked at the ignitor which looked fine, but since it was not glowing and this is a common part, I replaced it with a new one (That was no help).
I checked the fuse on the circuit board (good), and found out about the diagnostic codes. (The diagnostic code is flashing 3 blinks - would this cause these symptoms with the draft fan running and no ignitor glowing ?)
I am going to remedy the problems shown by the diagnostic code, but I am unsure if there may be another problem since the ignitor is not glowing and I have 2 children coming home from school to a home with no heat, so I want to make sure I don't replace anoher part un-necessarily and still not be able to make it run.
Thanks to anyone who answers this!
