Carrier 58WAV Furnace Door Switch
The furnace door switch prevents initial fan and ignition sequence from turning on in order to prevent injury and fire. It is extremely important that the device is swapped out quickly if you find it to be faulty.
How can I tell if my safety switch on the furnace door is almost dead?
- The whole system will not operate whether the door is off or on
- The furnace door switch looks as if it has been broken badly
