Goodman GDH80453AXCA Furnace Door Switch
The furnace door switch prevents initial fan and gas ignition from starting in order to prevent injury and fire. Do not try to fix it, just have it exchanged for a new one quickly if you see that it is broken.
What red flags are there that my safety door switch is not working properly?
- The door switch appears as though it has been beat up
- The system will not run whether the door is open or closed
