Carrier 48XP048090300 Furnace Door Switch
The job of the furnace door switch blocks the fan and burner being triggered to start so as to stop a potential explosion. Do not waste time and have it traded for new one quickly if you suspect that it is not working.
What are the clues to watch out for to know my safety door switch is in need of a replacement?
- The safety door switch seems eroded
- The furnace will not run whether the door is off or on
