Carrier 50HJQ012 Furnace Door Switch
The furnace door switch prevents the draft inducer and ignitor from starting so as to stop a potential explosion. Do not try to fix it, just have it exchanged for a new one immediately if you can, if you see that it is broken.
Signs the switch on your furnace door needs replacing
- The safety door switch looks like it is worn
- The furnace does not fire up whether the door is off or on
