This genuine Rheem air pressure switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. Functioning as an air proving sensor, it monitors the draft created by the inducer motor to ensure combustion gases are being safely exhausted before the ignition sequence begins. Rated at -0.60" WC (Water Column), this vacuum switch prevents the furnace from operating if it detects a blocked flue, venting issues, or inducer motor failure. Engineered for precision and reliability, this replacement part is essential for restoring proper heating performance and maintaining a safe environment in residential or commercial heating applications.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
