Carrier 48GP048090300 Furnace Door Switch
A furnace door switch is a safety feature that stops initial fan and ignition sequence from switching on in order to prevent injury and fire. You must have the device exchanged for a new one at once if you find it to be faulty.
What are the indications that my safety switch on the furnace door has to be replaced?
- The HVAC system does not function even with the door closed
- The door mechanism appears as though it has been beat up
