Whirlpool ATE0945SPP0 Furnace Door Switch
A furnace door switch is a switch that blocks the fan and ignition sequence from starting in order to prevent injury and fire. Do not waste time and have it switched out as quick as you can if you see that it is broken.
Signs of a declining safety door switch
- The HVAC system does not begin to work whether the door is open or closed
- The switch has been breaking apart
