A furnace door switch is a safety feature that inhibits the fan and other risky devices from starting in order to prevent injury and fire. You should really have it replaced ASAP especially if you suspect it is not working properly.
What signals that my furnace door switch is not working right?

You do not have to install the replacement part alone. Look for a professional locally to hire and install the part for you.
