Carrier 50JZ036300 Furnace Door Switch
The job of the furnace door switch blocks initial fan and ignitor from switching on so as to avoid injuries. It is quite important to have it substituted for a new part quickly if it is not working in order to prevent injuries.
What warnings are present when my furnace door switch is crapping out?
- The HVAC system cannot run even when you close the door
- The door switch appears to be eroded
