Ensure your heating system operates safely and efficiently with this high-quality air pressure switch, specifically calibrated at 1.11" WC for Rheem and Ruud furnaces. This air-proving switch acts as a vital safety sensor, monitoring the vacuum pressure produced by the draft inducer motor to verify proper airflow before allowing the furnace to ignite. If your HVAC system is experiencing ignition failure or intermittent shut-offs, replacing a worn or defective pressure switch is a common solution. Designed for reliability and precision, this component prevents the accumulation of gases by ensuring the exhaust system is functioning correctly. It is an essential replacement part for maintaining the performance and safety standards of your residential or commercial gas furnace.
