Ensure the safety and efficiency of your heating system with this high-quality air pressure switch, specifically designed for use in Ruud and Rheem HVAC units. As a critical air-proving safety device, this pressure switch monitors the draft inducer motor to verify proper airflow before allowing the ignition process to begin. By sensing a pressure differential of 0.30" WC, it prevents the furnace from operating under unsafe venting conditions, such as a blocked flue or a failing inducer fan. This reliable replacement part is essential for homeowners and technicians looking to repair furnace startup issues and maintain optimal combustion performance.
