Ensure the safe and efficient operation of your heating system with this premium air pressure switch. Designed specifically for gas furnaces and HVAC units, this air proving switch acts as a vital safety mechanism by monitoring the negative pressure generated by the draft inducer motor. It confirms that the exhaust system is venting combustion gases properly before allowing the furnace to ignite. If your heating unit is experiencing startup failures or cycling issues, a faulty pressure switch is often the cause. This high-precision component is calibrated to a -0.70" WC setpoint, providing reliable performance and peace of mind during the cold months. Built with durable materials to withstand the rigors of frequent cycling, this switch is an essential replacement part for maintaining residential HVAC safety standards.
