Product Details

Description

Ensure your heating system operates safely and efficiently with this replacement air pressure switch for residential gas furnaces. Designed as a critical safety component for Goodman and Amana HVAC units, this air proving switch monitors the vacuum pressure created by the draft inducer motor. It prevents the furnace from igniting if the venting system is obstructed or if the inducer motor fails to provide adequate airflow. If your furnace is short-cycling or displaying pressure switch fault codes, this -1.20" WC calibrated switch is an essential replacement part to restore reliable heating performance. Built for durability and precise sensing, it helps maintain the integrity of the combustion process in high-efficiency heating systems.
