    Goodman Furnace ignition not occurring
    Hello everyone, I have a GMP075-4 Goodman gas heating & air conditioning that comes on but no ignition occurs. I have done the minor troubleshooting process written on the instruction sheet but that didn't help. I turned off the power supply to the furnace and turned off the ignition switch and left it for five minutes and powered it up but the ignition didn't occur. I'm confused on what next to do. I don't want to call in a professional only to find out that it was something minor I could have checked myself. Please does anyone know what could be wrong?

    Is this hot surface ignition? Does the ignitor glow?

    Actually the Ignitor does not glow. I also took your advice and scheduled an apt. with a pro. Thank you very much!

    Ignitor might be bad, or the pressure switch, isn't even letting the cycle get that far to turn it on. Probably just a bad ignitor the repair bill should be less than $200 with the trip charge.

    I had the same symptoms, my pressure switch line was blocked with lint. I was getting a blocked outlet, no exhaust flow trouble signal.
    Another time it would fire for a couple seconds, then shut down. It was the flame sensor. I removed and steel wooled it. Fired right up after that.

    If you are careful you can pull the igniter out and inspect, you will see a darker burned spot with a very small crack init if its bad,, be careful they are very fragile,, if so you could fix yourself for around 50 bucks if you can get them to sell you the part

Goodman furnace [ 17 Answers ]

I have a goodman furnace. Forced air. No a/c. I turn the power on and she starts. Thermostat is off. No wires are crossed that are visible. The pilot does not ignite but the heating element is on. No gas seems to be coming through. Any suggestions? The furnace is only a year and a half old.
