International Comfort Products PA5530AKA1 Furnace Door Switch
This switch stops initial fan and gas ignition from turning on so as to stop a potential explosion. You should have the switch be substituted for a new part as quick as you can if it is damaged so as to prevent something bad happening.
What signals that my safety switch on the furnace door is in need of a replacement?
- The switch looks like it is removed
- The furnace will not start whether the door is open or closed
