The pressure switch monitors gas supply pressure and signals the control board to allow or interrupt the ignition sequence based on detected pressure levels. When this switch fails or drifts out of calibration, the unit will typically lock out before ignition, refuse to fire on a call for heat, or cycle off unexpectedly — leaving you with no heat on the coldest days.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e LP (propane) gas pressure switch | 6.5\" W.C. cut-out pressure setting | OEM part number HK02LB008 | Cross-reference: GFS3451-4036 | Factory-calibrated — no field adjustment required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized part, manufactured to exact pressure tolerances. Aftermarket substitutes may carry ±10–15% pressure variance, risking nuisance lockouts or unsafe gas flow conditions — especially critical on LP systems where pressure regulation is tighter than natural gas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Turn off gas supply and power before servicing. Tools needed: 1\/4\" nut driver, flat-head screwdriver, manometer (recommended for LP verification), and needle-nose pliers for hose barb connections.
