Product Details

Description

Ensure your heating system operates safely and efficiently with this replacement air pressure switch for Lennox and Armstrong furnaces. This 0.55" WC air proving switch is a vital safety mechanism that monitors the pressure differential created by the inducer motor. It confirms proper venting and airflow before allowing the furnace ignition sequence to proceed, preventing the buildup of dangerous exhaust gases. Ideal for repairing HVAC units experiencing ignition failures or pressure-related error codes, this durable switch provides the precise calibration needed for reliable climate control. Whether you are performing routine maintenance or a critical repair, this pressure sensor ensures your forced-air furnace meets factory safety standards.
