Product Details

Description

This dual air pressure switch is a critical safety component designed for modern high-efficiency gas furnaces. Functioning as an air proving switch, it monitors the vacuum pressure created by the draft inducer motor to ensure that combustion gases are being safely exhausted before the ignition cycle begins. With its Single Pole Single Throw (SPST) configuration, this part acts as a vital safeguard, preventing the furnace from operating if it detects venting obstructions or motor failure. If your heating system is failing to ignite or shutting down prematurely, a faulty pressure switch is often the culprit. This high-precision replacement part ensures your HVAC system maintains optimal safety and performance standards during the heating season.
