Frigidaire FRS093LW10 Furnace Door Switch
The job of the furnace door switch blocks the draft inducer and burner from turning on so as to avoid injuries. Do not try to fix it, just have it substituted for a new part ASAP if you see that it is broken.
How do you know when your safety furnace door switch is dying?
- The furnace door switch seems messed up
- The HVAC system will not engage whether the door is open or closed
