Goodman GMH Furnace Door Switch
The furnace door switch is a safety switch which inhibits the draft inducer and other risky devices from switching on so as to stop a potential explosion. You must have the device switched out as quick as you can if it is causing you problems.
General indicators that your safety switch on the furnace door will not live much longer
- The furnace cannot run whether the door is off or on
- The switch looks like it is eroded
