Payne PH2PNB024000AA Furnace Door Switch
A furnace door switch is a switch that stops the draft inducer and burner from activating so as to stop a potential explosion. Do not try to fix it, just have it changed ASAP if it is causing you problems.
What red flags are there that my furnace door switch is about to go out?
- The door mechanism is stuck
- The HVAC system will not even begin to start with the door closed
