Product Details

Description

This premium Air Pressure Switch is a critical safety component designed for gas-fired furnaces and heating systems. Functioning as an air proving switch, it monitors the differential pressure created by the inducer motor to ensure the venting system is clear and operating safely. With a precise set point of -0.55" WC (Water Column), this switch is engineered to prevent ignition if proper airflow is not detected, protecting your appliance from hazardous operating conditions. It is an ideal replacement part for HVAC systems experiencing ignition failure, frequent cycling, or inducer motor issues. Reliable and durable, this component ensures your heating equipment maintains peak efficiency and safety compliance.
