International Comfort Products HXA248AKA1 Furnace Door Switch
A furnace door switch is a safety feature that inhibits the draft inducer and other risky devices being triggered to start so as to stop a potential explosion. Do not try to fix it, just have it substituted for a new part immediately if you can, especially if you suspect it is not working properly.
What happens when my safety switch on the furnace door really needs to be replaced?
- The furnace door switch is beat up
- The HVAC system will not engage even when you close the door
