You have a common problem. You are losing the 24v somewhere. You will need a meter to repair it, as there are many part that could be the problem. Changing parts without knowing can get expensive. If you have a meter and know how to use it, I can help you.

Heater will fire but wont stay lit.


I assume that you are referring to a natural gas forced air furnace. If so you just described the symptoms of a dirty flame sensor. Remove the sensor with a 1/4" nutdriver. clean the flame sensor with a small piece of fine grit sandpaper or emery cloth. replace the sensor and turn the furnace back on.
Good luck.....

I have a goodman gmpn 100-4 REVB furnace that will not stay lit


If the igniter lights the burners the ignitor..... is not bad. Its like a light bulb.... it works or ot doesn't.
You are describing a dirty flame sensor. Dishonest contractors will sell you a new ignitor but clean the flame sensor when the are installing the ignitor. It is located at the opposite end of the burners than the ignitor. It has one wire going to it. Remove it and clean the rod with a piece of fine grit sandpaper. this should be done every year before heating season.
Good luck

Ignition failure code on


Sounding like a flame proving device is failing to sense flame. Try to clean the device with some steel wool. It is located right next to the last burner looks like a thick wire. Take the steel wool and gently rub the carbon that has built up off. Should only take 4 or 5 strokes. Let me know it that did it. Ken
