Goodman GCVC90704CXAA Furnace Door Switch
A furnace door switch is a switch that inhibits the blower and ignitor being triggered to start so as to stop a potential explosion. Do not try to fix it, just have it switched out swiftly if you see that it is broken.
Subtle hints your furnace door switch will die soon
- The door switch appears as though it has been chipped
- The whole system does not turn on whether the door is open or closed
