York S1-024-27634-001 Pressure Switch the internal windings are likelyThe York S1 024 27634 001 Pressure Switch is a critical safety component designed for precise differential pressure sensing in York, Luxaire, and Coleman gas furnaces. This SPNO (Single Pole Normally Open) switch is factory calibrated to a . 65" WC setpoint, closing on a fall in pressure to ensure the induced draft motor is maintaining adequate venting before the ignition sequence initiates. Engineered for high cycle reliability in residential heating
