The Goodman A3468601 3/16" ID Pressure Switch Tubing is genuine OEM hose for the GMV80905CXA gas furnace. This small-diameter tube connects the pressure switch to the inducer draft port, transmitting the negative pressure signal the switch needs to confirm proper venting before the burners are allowed to fire. Cracked, brittle, or clogged tubing is a frequent cause of pressure-switch-open lockout faults and intermittent no-heat calls.

Specifications

Inside diameter: 3/16"
Type: Pressure switch sensing tube / hose
Function: Draft-pressure signal transmission
Fits: Goodman GMV80905CXA and compatible models
Brand: OEM Goodman / Amana

OEM vs. Generic

This factory OEM tubing uses heat- and moisture-resistant material rated for the temperatures near the inducer and heat exchanger. Generic tubing can harden, collapse, or degrade quickly in that environment, leading to false pressure-switch trips. At only a few dollars, the genuine OEM hose is inexpensive insurance against nuisance lockouts.

Install Difficulty

Very Easy (1/5) — Slip the old tube off both barbed fittings and press the new length on, matching the original routing so it does not kink or sag where condensate can pool. Disconnect power first and inspect the pressure port for blockage while you have access.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman GMV80905CXA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman GMV80905CXA — 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 GMV80905CXA — 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.
