Lennox XC13-060 Furnace Door Switch
A furnace door switch is a safety feature that blocks the blower and burner from starting in order to prevent injury and fire. You should really have it traded for new one quickly if you suspect that it is not working.
What are some indications that my safety switch on the furnace door has a need to be replaced?
- The furnace door switch seems broken badly
- The furnace does not function whether the door is off or on
