This normally-open switch monitors the vacuum created by the inducer\/draft motor and closes at a \u003cstrong\u003e-1.4 inch water-column\u003c\/strong\u003e setpoint to confirm safe venting before the ignition sequence begins. If the flue is blocked, the inducer is weak, or a hose is cracked, the switch stays open and locks out the burner — protecting your home from carbon-monoxide spillage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSetpoint: -1.4 in. water column (WC)\u003c\/li\u003e\n\u003cli\u003eConfiguration: Single-pole, Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003eFunction: Combustion air \/ venting proving switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUN050-2B furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370107\u003c\/li\u003e\n\u003cli\u003eConnection: Standard spade terminals with pressure-tap port\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370107\u003c\/strong\u003e is calibrated to the exact -1.4\" WC trip point specified for this furnace, which is critical for a safety device — an incorrectly rated switch can nuisance-trip or, worse, allow ignition under unsafe draft.
