Goodman 11112501S Pressure Switch (-0.33" WC, Normally Open)

The Goodman 11112501S is a genuine OEM air-pressure (draft) switch designed for the WGGE4324A070MAB gas furnace and compatible Goodman/Amana models. This normally-open switch verifies that the inducer draft motor is producing correct venting airflow before the control board allows the burners to ignite. When the switch senses the proper negative pressure of -0.33 inches of water column (WC), it closes and signals the board that it is safe to proceed — a critical safety function that prevents unsafe or incomplete combustion.

OEM vs. Generic

This is a genuine Goodman OEM switch, calibrated to the exact -0.33" WC trip point specified for your furnace. Generic aftermarket switches often carry loose tolerances that can cause nuisance lockouts or fail to protect against a blocked flue. For a combustion-safety component, matching the OEM setpoint is strongly recommended.

Installation Difficulty

Easy (1 of 5). Replacement typically takes 15–20 minutes: cut power to the furnace, disconnect the two spade terminals and the rubber tubing, unscrew the switch bracket, and reverse the steps with the new unit. Always confirm no soot or moisture is present in the tubing. If you are not comfortable working around gas appliances, use a licensed HVAC technician.

How do I replace the pressure switch on my Goodman WGGE4324A070MAB — 11112501S?

Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

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

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Is this pressure switch compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Goodman pressure switch?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
