Carrier 58MSA08012116 Furnace Door Switch
The furnace door switch is a safety switch which blocks the vent fan and other risky devices from turning on in order to prevent injury and fire. You should have the switch be exchanged for a new one swiftly if it is damaged so as to prevent something bad happening.
Main clues the safety door switch needs replacing
- The HVAC system does not run even when you close the door
- The door mechanism seems bent badly
