Product Details

Description

Restore reliable operation to your heating system with this high-quality dual-stage air pressure switch. Designed for high-efficiency two-stage furnaces, this air proving sensor acts as a vital safety mechanism by monitoring the negative pressure produced by the draft inducer motor. It ensures that the exhaust venting is clear and the motor is functioning correctly before allowing the furnace to enter its ignition sequence. Featuring factory-calibrated set points of -0.35" WC and -0.65" WC, this switch is specifically engineered to handle the varying airflow requirements of multi-stage heating cycles. It is a critical replacement part for resolving furnace startup issues, ignition failures, and safety lockouts in residential gas heating systems.
