Product Details

Description

This premium two-stage air pressure switch is a critical safety component designed for multi-stage gas furnaces and HVAC systems. Often referred to as an air proving switch, this device monitors the pressure differential created by the draft inducer motor to ensure that exhaust gases are being properly vented before the ignition process begins. Featuring precise dual-stage calibration with set points at 0.30" WC and 0.59" WC, it allows your heating system to safely transition between low and high-fire heating cycles. Replacing a faulty pressure switch is essential for restoring furnace functionality, preventing ignition failure, and ensuring the safe operation of your home's forced-air heating system. This part is engineered for high sensitivity and long-term reliability in demanding residential heating environments.
