This genuine Goodman 11112501S Pressure Switch is a normally-open (NO) air-proving safety switch rated at -0.33" WC, designed as a direct OEM replacement for the WGGE4542A115MAA gas furnace. The pressure switch confirms that the inducer (draft) motor is pulling proper airflow before allowing the ignition sequence to proceed — a critical safety interlock that prevents the furnace from firing without adequate venting.

Specifications

OEM Part Number: 11112501S
Switch Type: Normally Open (NO)
Trip Setpoint: -0.33" WC (water column)
Fits Model: WGGE4542A115MAA
Function: Combustion draft / air-flow proving safety

OEM vs. Generic

Pressure switches are calibrated devices — the exact setpoint matters. This OEM switch is factory-set to -0.33" WC, guaranteeing the furnace proves draft at the manufacturer's spec. Generic switches with the wrong setpoint or hysteresis can cause chronic no-heat lockouts or, worse, defeat the safety function. Choosing OEM protects both reliability and combustion safety.

Installation Difficulty: Easy to Moderate

A common no-heat repair. Shut off power, note tubing orientation, transfer the two wire leads and the pressure hose, and mount the new switch. Verify the switch closes on a call for heat using a manometer or by confirming the ignition sequence completes. Typical job time: 20–30 minutes. Inspect the hose and port for blockage while you're in there.

My furnace shows a pressure switch error. What do I replace?
