Goodman 11177113 Combination Pressure Switch

The Goodman 11177113 is a genuine OEM dual-stage combination pressure switch engineered for the AMV90453BXBB variable-speed condensing furnace and other compatible Goodman/Amana 90%+ AFUE models. This gray-bodied switch monitors negative draft pressure across the induced-draft blower and heat exchanger, proving safe venting before the ignition sequence is allowed to proceed. A failed pressure switch is one of the most common causes of a furnace that ignites briefly and then locks out.

Specifications

  • Type: Combination (dual) negative pressure switch
  • Trip points: -.30" WC and -.75" WC (inches water column)
  • Housing color: Gray
  • Equipment: Gas furnace (condensing / 90%+ AFUE)
  • Fit: AMV90453BXBB and compatible Goodman/Amana models
  • OEM Part Number: 11177113

OEM vs. Generic

The OEM 11177113 ships with factory-calibrated trip pressures and the correct terminal and tube-port configuration, guaranteeing an exact fit and reliable safety operation. Generic aftermarket switches may carry similar pressure ratings but frequently differ in bracket geometry, port orientation, or calibration tolerance — leading to nuisance lockouts. For a listed safety component, the OEM part is strongly recommended.

Installation Difficulty

Moderate (2/5). Requires shutting off power and gas, transferring the rubber sensing tubes to matching ports, and reconnecting the wiring harness. No specialty tools needed, but correct tube routing is essential. HVAC technician recommended for warranty and safety.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMV90453BXBB — 11177113?
Yes. This is the factory-specified OEM pressure switch for the Goodman AMV90453BXBB — 11177113. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the pressure switch on my Goodman AMV90453BXBB — 11177113?
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.
