Lennox G40DF-60D-135 Furnace Door Switch
The job of the furnace door switch blocks the draft inducer and ignition sequence from starting so as to stop a potential explosion. Do not try to fix it, just have it switched out as soon as you can if it is damaged so as to prevent something bad happening.
What warnings are present when my safety door switch is in need of a replacement?
- The whole system does not run whether the door is off or on
- The door mechanism appears to be bent badly
