International Comfort Products FBF125J20A1 Furnace Door Switch
The furnace door switch is a safety switch which prevents the draft inducer and burner from turning on so as to stop a potential explosion. It is quite important to have it traded for new one as soon as you can if you suspect that it is not working.
