Desa R155B Furnace Door Switch
The job of the furnace door switch blocks the fan and ignitor from activating in order to prevent injury and fire. You should really have it swapped out as soon as possible if it is causing you problems.
What are the indications that my furnace door switch is about to stop working?
- The system does not turn on whether the door is open or closed
- The door mechanism appears as though it has been removed
