This safety switch confirms the induced-draft blower has established proper venting before the control board allows ignition. A weak diaphragm or out-of-spec setpoint is a leading cause of intermittent no-heat calls, ignition lockouts, and Code 12\/13-style pressure faults.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 0130F00001P\u003c\/li\u003e\n\u003cli\u003eSet point: -1.2 in. w.c.

Generic switches with a nearby-but-different setpoint cause the furnace to trip early or fail to prove draft — the classic short-cycling and lockout complaints. On a safety device, matching the exact OEM calibration is critical.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Easy–Moderate (2\/5).\u003c\/strong\u003e Power down the furnace, photograph and transfer the wiring and hose to the new switch, then mount it in the original orientation. Confirm the sensing hose is clear and correctly routed. On restart, verify the switch closes and the burner lights. Typical time: 20–30 minutes.
