The Goodman B1370150 will stop the furnace from operating should the vent become blocked. To check this switch, firstly, place the furnace in operation. Secondly, remove the hose from the switch. As a result, the gas burners should extinguish. If not, then more than likely the switch is bad. Replacing the hose should allow the furnace to operate normally.
