Lennox CB29M-31 Furnace Door Switch
The job of the furnace door switch inhibits the fan and gas ignition from turning on so as to stop a potential explosion. Do not waste time and have it traded for new one at once if it is damaged so as to prevent something bad happening.

- The door mechanism appears as though it has been eroded
