International Comfort Products HAC224GKA4 Furnace Door Switch
The furnace door switch is a safety switch which inhibits the draft inducer and other risky devices from turning on so as to avoid injuries. Do not try to fix it, just have it replaced quickly especially if you suspect it is not working properly.

- The safety door switch appears as though it has been eroded
