The Lennox 71G15 Blocked Vent Switch is for use with Lennox gas-fired forced air furnaces. It is designed to protect the furnace blower and other components from poor combustion air circulation, which can cause a fire. This replacement blocked vent switch features a mounting hardware kit and a one-year warranty.
When your Lennox 71G15 furnace keeps shutting off, the first thing you should do is check the blocked vent switch. This switch is inside the blower compartment. It's a tiny metal lever that sticks out of the box on the right side wall and acts as a thermostat for the blower. If it becomes blocked by dust or debris, or if it's defective, the furnace will overheat to protect itself and shut down. To fix this problem yourself, first clear any obstructions so that air can flow freely. Then replace any broken switches."
