Goodman P1256808F Furnace Door Switch
The furnace door switch is a safety switch which prevents the blower and burner from turning on so as to stop a potential explosion. You should have the switch be exchanged for a new one as quick as you can especially if you suspect it is not working properly.
Red flags the safety door switch is dying
- The system does not operate even with the door closed
- The door mechanism appears as though it has been worn down
