Question about Goodman GMS90703BXA Heater
Can anyone help? Gas furnace will ignite but won't stay lit. I thought it was the flame sensor, but I replaced it and still not working? Could the be a circuit board problem? If so how can I be sure? Goodman GMPN 120-5
Furnace will start then sec later it will turn off. Then you can here that its trying to trun on.

Try replacing the filter. Low air flow will allow the furnace to overheat. Sounds like a simple answer. Wish I had tried it before buying a flame sensor and controller. Live and learn I guess.
