Goodman DSXC160601 Furnace Door Switch
A furnace door switch is a switch that blocks the blower and burner from activating so as to stop a potential explosion. It is quite important to have it swapped out immediately if you can, especially if you think it is defective.
Hints of a defective safety furnace door switch
- The switch looks eroded
- The HVAC system does not function whether the door is off or on
