The Goodman A3468601 Pressure Switch Tubing is the genuine OEM 3/16" inside-diameter hose that connects the pressure switch to the inducer draft port on the AMS81155CXAA 80% AFUE furnace and related Goodman/Amana models. This small but critical part carries the negative-pressure signal the switch uses to confirm proper venting before the burners light.

  • Inside diameter: 3/16"
  • OEM Part Number: A3468601
  • Fits model: AMS81155CXAA (80% AFUE furnace)
  • Brand: Goodman / Amana (Daikin family)
  • Material: High-temp silicone / rubber tubing
  • Category: Pressure Switch

OEM vs. Generic

OEM tubing is rated for the temperatures and vacuum levels found at the inducer port and resists cracking and collapse. Generic hardware-store tubing can harden, kink, or leak, leading to false pressure-switch faults and no-heat lockouts. The genuine A3468601 ensures an accurate draft signal.

Why Replace It

Cracked, brittle, or clogged tubing is a common cause of pressure-switch error codes. Replacing it restores a leak-free connection and reliable ignition sequencing.

Install difficulty: Easy. Under 10 minutes with no special tools — slip the new tube onto the switch and inducer barbs. Shut off power first and route the tube away from hot surfaces so it doesn't sag or trap condensate.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMS81155CXAA — A3468601?
Yes. This is the factory-specified OEM pressure switch for the Goodman AMS81155CXAA — A3468601. 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 AMS81155CXAA — A3468601?
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.
