Question about Goodman GMS90703BXA Heater
I have a goodman everthing works, its only 3 years old but when I turn the heat on the pilots will not light. I read the instructions on the panel, did as it said and the pilot still will not light.
If in fact you have the above listed furnace, you do not have a pilot but electronic ignition. You will need to remove the front cover on the furnace, tape down the door safety switch and then have someone help you by turning up your thermostat to a very high setting. Watch and listen inside the furnace. There should be some blinking going on at the control board followed by a small blower fan starting up. Then after 10-15 seconds there should be a click followed by an orange glow viewed thru the viewing window to the burner section. In a few seconds the gas valve should click and the burners will ignite. There is a safety switch that will sense flame and then keep the gas going to the burners. If it does not sense it, it will shut it off within 10 seconds. If all is well so far, your blower will turn on in about 90 seconds after flame. There is a diagnostic code chart on the back side of the access door if you get an error code (blinking) on the control board.
Always check little things like air filter, condensate drain and broken or loose wires.
