Goodman GSX130181 Furnace Door Switch
This switch blocks initial fan and ignitor from switching on in order to prevent injury and fire. You should really have it switched out promptly especially if you suspect it is not working properly.
What are the indications that my safety furnace door switch really needs to be replaced?
- The switch seems to be stuck
- The furnace does not begin to work whether the door is off or on
