International Comfort Products PA5560AKA5 Furnace Door Switch
A furnace door switch is a switch that inhibits the vent fan and other risky devices from turning on so as to stop a potential explosion. You should really have it replaced immediately if you can, if you find it to be faulty.
Simple indications of a poorly working furnace door switch
- The HVAC system cannot run even when you close the door
- The switch looks like it is eroded
