I have a Goodman airconditioning & heating unit Model # GMNT
There's a relay switches inside the heater at the base right hand side the switch will not stay in, so is there any way that I can get it to start. Im trying anything even the thermastate. Anybody has any information. Or locaton that I can see information on this subject. Thank you

Are you talking about the switch that the bottom door (when installed) keeps the button pushed in?
