The Armstrong Furnace R102613-01 Pressure Switch is a critical OEM safety component engineered for 2-stage 80% and 90% gas furnaces

Technicians typically look for heavy frost or ice buildup on the coils

Reliable cross-lighting performance provided by integrated carryover flaps for consistent ignition cycles

or the compressor failing to start while the fan remains operational

Hankison 3233283 Pressure Switch Els PW 17895 This model is technically identicalThe Hankison 3233283 High Pressure Switch M R is a critical safety component engineered for precision monitoring in high pressure compressed air and refrigeration systems. As a manual reset (M R) control, this switch is designed to provide fail safe protection by deactivating the system when internal pressures exceed the calibrated safety threshold, preventing catastrophic equipment failure and ensuring operational safety for industrial air dryers.
