Question about Goodman GMS90703BXA Heater
Lock-Out happens when the unit tries to start and fails after three consecutive attempts. Usually it's the flame sensor or the igniter. Its best to be in front of the unit while it attempts to start to see which component is not working. It will be in this order- The induction motor comes on, then the igniter which will be the glow you see, then the gas valve opens and flames start. If the flames never start, the igniter is bad, if you get the flames, but then the click back off, you probably have a bad flame proving rod, which is located in front of the burners to one side. You can clean these to get them to work most of the time. Just use a lite abrasive material and clean the rod. Be sure to shut all power off before doing so. Hope this helps and good luck!
