The pressure switch is a critical safety component designed to prove that the draft inducer motor is spinning at the correct RPM and generating sufficient negative pressure before allowing the furnace to proceed through the ignition sequence. When this switch fails or sticks open, the inducer will run continuously but the burners will never fire — leaving you with a furnace stuck in a safety lockout with no heat. This assembly includes two individual switches mounted on a factory bracket, covering both the low-stage (0.80\" W.C.) and high-stage (1.70\" W.C.) proving circuits required by the 2-stage combustion design.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Dual-switch assembly | Stage 1: –0.80\" W.C. | Stage 2: –1.70\" W.C. | Mounted on Honeywell 27555BM-01 bracket | Honeywell cross-reference: BA20238 | OEM part number: HK06NA016 (superseded by HK06MB025)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM-spec assembly with factory-calibrated switching points.
