Lennox G40DF-36A-070X Furnace Door Switch
The furnace door switch blocks the draft inducer and ignitor being triggered to start so as to stop a potential explosion. Do not waste time and have it traded for new one immediately if you can, if you suspect that it is not working.
What are the clues to watch out for to know my switch on the furnace door is on its last leg?
- The whole system does not begin to work even with the door closed
- The furnace door switch looks like it is breaking apart
