The Goodman A3468601 is a genuine OEM 3/16-inch inside-diameter pressure switch tubing designed for the AMS80704BXA gas furnace and other compatible Goodman and Amana equipment. This flexible hose carries the negative-pressure signal from the inducer draft port to the pressure switch, allowing the control board to confirm safe venting before ignition. Cracked, brittle, or disconnected tubing is one of the most common causes of a furnace that clicks but will not fire.

  • Inside diameter: 3/16 in.
  • Function: Draft/pressure sensing signal line
  • Material: High-temperature silicone-grade hose
  • Fits: AMS80704BXA and compatible Goodman/Amana 80% furnaces
  • Part number: A3468601

OEM vs. Generic: The genuine A3468601 tubing is rated for the sustained heat and vibration inside a furnace cabinet, resisting the hardening and cracking that causes generic hose to fail within a season or two. Generic aftermarket tubing may cost slightly less up front but often does not match the OEM temperature rating, leading to repeat nuisance lockouts.

Install difficulty: Easy (DIY-friendly). Replacement takes only a few minutes with no tools beyond a pair of pliers to seat the connections. Always shut off power and gas before servicing, and route the new tubing exactly as the original to avoid kinks or contact with hot surfaces. If you are unsure, consult a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMS80704BXA — A3468601?
Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMS80704BXA — 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 tubing on my Goodman AMS80704BXA — 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 tubing 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 tubing?
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.
