International Comfort Products C8MPL100F20B1 Furnace Door Switch
A furnace door switch is a switch that blocks the vent fan and burner from switching on so as to avoid injuries. You should have the switch be changed as quick as you can if it is not working in order to prevent injuries.
Simple indications of a worsening safety door switch
- The switch appears as though it has been worn down
- The whole system does not begin to work whether the door is off or on
