Goodman A3468601 Pressure Switch Tubing (3/16" ID)

The Goodman A3468601 is a genuine OEM 3/16" inside-diameter pressure switch tube for the GMV80905CXBA gas furnace. This small hose carries the negative-pressure signal from the inducer/collector box to the pressure switch, allowing the furnace to confirm proper draft before the burners fire. Cracked, hardened, or clogged tubing is a leading cause of nuisance pressure-switch lockouts and no-heat calls — a quick, inexpensive fix that restores reliable ignition.

Specifications

OEM Part Number: A3468601
Inside Diameter: 3/16"
Type: Pressure switch sensing tube / hose
Material: Heat- and moisture-resistant tubing
Fits Model: GMV80905CXBA and compatible Goodman/Amana furnaces
Equipment: Gas Furnace

OEM vs. Generic

Genuine Goodman tubing is cut to the correct length and rated for the temperature and vacuum of the furnace environment. Generic hose can be the wrong bore or degrade quickly near heat, leading to leaks and false pressure faults. OEM ensures an accurate pressure signal every cycle.

Install Difficulty

Very Easy (1 of 5). Slips onto the switch and inducer ports by hand in under 10 minutes — no tools required. Power down the furnace, route the hose without kinks, and seat both ends fully. A great preventive-maintenance replacement.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GMV80905CXBA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GMV80905CXBA — 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 GMV80905CXBA — 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.
