Question about Goodman GMS90703BXA Heater
I have a 4yr old GMT 115-5b unit that wont ignite. Fan comes on, gas flows and then it shuts down because it isnt igniting. Then it cycles again and does the same thing over and over. I have done the reset process as described on the cover, to turn the switch to off, wait 5 min and then turn it back to on.
Couple things without more info is little hard,,,first not familliar with this paticular model but I believe it has a glo igniter,,which will be located next to the burners,,should be one or two scres holding it in,if this is not glowing than u need to pulll it out and look for a crack in it if its cracked u need to replace. If this is electronic ignition will have a metal spark ignition,,the glow ignitor will be ceramic by the way,,also if u pull out the glow ignitor do not touch the element with your hands while inspecting or replacing for the oil on your hands will cause it to fail sooner. sorry back to the metal spark ignition if it is not sparking than chances are u have a problem with the combustion fan motor shutting down the gas valve before it lights. I just posted on a goodman about the fan motor and the two types and how to fix. good luck.
