Ensure the safe and efficient operation of your heating system with this premium air pressure switch. Designed for use in residential gas furnaces, this air proving switch functions as a vital safety mechanism by monitoring the draft produced by the inducer motor. It prevents the furnace from igniting if it detects an obstruction in the flue or insufficient venting pressure, protecting your home from potential hazards. If your furnace is failing to start or cycling improperly, a faulty pressure switch is often the culprit. This component is engineered for precise calibration at a -0.90" WC setpoint, providing reliable performance and peace of mind during the heating season.
