Pressure switches prove that the inducer motor has established adequate draft before allowing the ignition sequence to proceed. A failed pressure switch causes the system to lock out before ignition, often displaying a fault code and leaving you with no heat. Common symptoms include the inducer running continuously with no ignition attempt, or repeated short-cycle lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 312926-252 — High Pressure Switch | 312926-258 — Low Pressure Switch | Factory-calibrated W.C.

Aftermarket switches frequently carry loose tolerances that can cause nuisance lockouts or — more dangerously — allow operation under unsafe draft conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Turn off power at the disconnect and gas supply before beginning. Tools needed: 1\/4\" nut driver, flat-head screwdriver, needle-nose pliers, and a manometer if verifying W.C. readings. Always inspect the inducer hose for cracks or blockages before replacing the switch, as a collapsed hose is a common root cause of pressure switch failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
