International Comfort Products TCA448AKA1 Furnace Door Switch

The job of the furnace door switch blocks initial fan and ignitor being triggered to start so as to stop a potential explosion. You should really have it exchanged for a new one as soon as you can if it is causing you problems.

How can I tell if my safety switch on the furnace door is almost going bad?
