Trane PTED070 Furnace Door Switch
This switch stops the draft inducer and ignition sequence from turning on in order to prevent injury and fire. You should really have it exchanged for a new one immediately if you can, if you find it to be faulty.
What are some hints that my furnace door switch is failing?
- The HVAC system does not even thing about starting with the door closed
- The door switch appears as though it has been eroded
