This 1.13" WC Air Pressure Switch is a vital safety component designed for forced-air heating systems and gas furnaces. Often referred to as an air proving switch, its primary function is to monitor the pressure generated by the draft inducer motor to ensure that flue gases are being properly vented. By verifying adequate airflow before allowing the ignition sequence to begin, this switch protects your HVAC system and home from potential hazards. If your furnace is experiencing startup failures or cycling off prematurely, a faulty pressure sensor may be the culprit. This high-quality replacement part offers reliable performance, ensuring your heating equipment operates efficiently and safely throughout the winter months.
