The Goodman A3468601 is a genuine OEM 3/16 inch ID pressure switch tubing designed for the GMTH090-5 gas furnace and related Goodman/Amana models. This small silicone/rubber hose connects the draft (vent) pressure switch to the inducer housing or collector box, allowing the switch to sense proper venting before the furnace fires.

Over time this tubing can harden, crack, kink, or clog with condensate — leading to pressure switch faults, ignition lockouts, and no-heat calls. Replacing it is one of the cheapest, highest-value furnace repairs.

  • Part Number: A3468601
  • Inside Diameter: 3/16 inch
  • Fits: Goodman GMTH090-5 furnace
  • Application: Draft/vent pressure switch sensing line
  • Material: High-temp flexible tubing

OEM vs. Generic: Genuine Goodman tubing is cut to the correct length and rated for the furnace's heat and condensate exposure. Generic hose may be the wrong bore or a lower temperature rating, causing early failure or a loose fit that leaks vacuum. For a sensing line, correct ID and fit are essential — OEM recommended.

Installation Difficulty: Easy — a true DIY repair. Power down the furnace, pull the old tubing off both barbed fittings, and press the new hose fully onto each nipple. No tools required in most cases.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GMTH090-5 — A3468601?
Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GMTH090-5 — 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 GMTH090-5 — 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.
