The Goodman A3468601 Pressure Switch Tubing is genuine OEM 3/16" ID draft-sensing hose for the Amana / Goodman AMH81405DXCC gas furnace. This flexible tube connects the inducer/vent tap to the pressure switch, transmitting the negative pressure signal that proves proper draft before the burners fire. Cracked, brittle, or clogged tubing is a frequent cause of pressure-switch lockouts and no-heat faults.

  • OEM Part Number: A3468601
  • Category: Pressure Switch Sensing Tube
  • Inside Diameter: 3/16" ID
  • Fits Model: AMH81405DXCC (and compatible Goodman/Amana furnaces)
  • Symptoms it fixes: Pressure-switch lockout, false draft faults, intermittent no-heat

OEM vs. Generic: The OEM tubing uses the correct 3/16" bore and heat-resistant compound sized to seal on the factory barbs without kinking. Generic tubing of the wrong ID or wall thickness can leak the pressure signal or collapse over the switch nipple, defeating the safety proof. OEM ensures an airtight sensing path.

Install Difficulty: Easy — cut to length, press onto the barbed fittings at the inducer tap and pressure switch. No tools required beyond a knife or scissors.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMH81405DXCC — A3468601?
Yes. This is the factory-specified OEM pressure switch for the Goodman AMH81405DXCC — 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 AMH81405DXCC — 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.
