Whirlpool ATE0753RPP0 Furnace Door Switch
A furnace door switch is a safety feature that blocks the vent fan and ignitor from starting so as to avoid injuries. You should really have it exchanged for a new one as quick as you can if you see that it is broken.
Key symptoms of an ineffective furnace door switch
- The HVAC system will not begin with the door closed
- The switch is beat up
