This high-quality furnace air pressure switch is a critical safety component designed for Rheem and Ruud heating systems. As an essential air proving switch, it monitors the negative pressure created by the inducer motor to ensure that combustion gases are being properly vented before the ignition process begins. Rated at 0.40" WC (Water Column), this switch is a common replacement part for furnaces that are failing to ignite or are shutting down due to venting issues. By verifying adequate airflow, it protects your HVAC system from unsafe operating conditions. This durable, precision-calibrated component is ideal for restoring the reliable performance of your gas furnace or heating unit.
