Nordyne 632566 Pressure Switch 328140-751 Operational Reliability: Specifically ported toThe Nordyne 632566 Pressure Switch is a critical safety component designed for specific gas fired furnaces and packaged units. As the direct replacement for 632566R, this differential pressure switch monitors the pressure drop across the heat exchanger, ensuring the induced draft motor is evacuating flue gases effectively before allowing the ignition sequence to proceed. This single pole, normally open switch is calibrated to precise OEM
