Product Details

Description

This high-quality air pressure switch is a vital safety component designed for York, Luxaire, and Coleman gas furnaces. Functioning as an air-proving switch, it monitors the negative pressure created by the inducer motor to ensure proper venting before the ignition sequence begins. This genuine factory replacement part features an updated calibration of -0.90" WC (Water Column), providing a reliable upgrade for older -1.00" WC switches. If your heating system is experiencing ignition failure or venting errors, this precision-calibrated sensor helps restore safe and efficient operation to your HVAC unit.
