The Goodman 20197308 Pressure Switch is a genuine OEM -.10 in. w.c. normally open (NO) air-proving safety control for the Amana/Goodman AMVC950453BXAB variable-speed condensing furnace. It works alongside the furnace's other draft controls to confirm proper inducer operation and a clear flue before the ignition sequence begins.

This normally open switch closes when the correct negative pressure is sensed. If it fails to close — due to a blocked flue, weak inducer, clogged drain, or a bad switch — the control board halts ignition and reports a fault, resulting in a no-heat condition. Restoring the correct switch keeps the safety chain intact.

  • Trip point: -.10 in. w.c.
  • Configuration: Normally open (NO)
  • Part number: 20197308
  • Fits: AMVC950453BXAB and compatible AMVC95 furnaces
  • Function: Proves inducer draft / combustion air path

OEM vs. Generic: Genuine 20197308 is factory-calibrated to the precise -.10" set point and NO configuration the AMVC95 board expects. Substituting a switch with a different set point or normally closed contacts can cause nuisance lockouts or bypass a safety. For pressure switches, always choose OEM.

Install difficulty: Easy. Disconnect power, move the sensing hose and spade terminals to the new switch, and mount it in the same position. Verify operation with a manometer on the next heat call. Basic hand tools only.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMVC950453BXAB — 20197308?
Yes. This is the factory-specified OEM pressure switch for the Goodman AMVC950453BXAB — 20197308. 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 AMVC950453BXAB — 20197308?
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.
