Description

Ensure your HVAC system operates safely and efficiently with this premium single-port air pressure switch. Designed as a critical safety component for gas-fired furnaces and packaged heating units, this air proving switch monitors the draft created by the inducer blower motor. It is calibrated to a precise 0.15" WC set point, ensuring that the heating cycle only begins when proper venting and combustion airflows are confirmed. This replacement part is ideal for troubleshooting furnace startup failures or resolving pressure switch lockout codes. Built for reliable performance and long-lasting durability, it provides the precise pressure sensing required for modern high-efficiency heating systems.
