Carrier 48XZ048130300TP Furnace Door Switch
The furnace door switch prevents the draft inducer and other risky devices being triggered to start so as to avoid injuries. Do not try to fix it, just have it swapped out quickly if you suspect that it is not working.
What are some indications that my safety switch on the furnace door has to be replaced?
- The door mechanism appears to be stuck
- The HVAC system does not operate whether the door is open or closed
