Fujitsu AOU9RL2 Furnace Door Switch
The job of the furnace door switch stops the draft inducer and gas ignition from starting in order to prevent injury and fire. It is crucial to have this part exchanged for a new one at once if it is damaged so as to prevent something bad happening.
Major clues of a barely functioning switch on the furnace door
- The HVAC system does not fire up whether the door is open or closed
- The safety door switch is messed up
