Trane TTZ036A100A1 Furnace Door Switch
A furnace door switch is a switch that blocks the draft inducer and gas ignition from starting so as to avoid injuries. Do not waste time and have it switched out immediately if you can, if it is causing you problems.
Clues the safety door switch will have to be replaced
- The furnace does not run even when you close the door
- The switch looks as if it has been breaking apart
