The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16" ID hose for the Goodman/Amana AMH80905CNAB gas furnace and compatible 80% AFUE models. This small tube carries the negative pressure signal from the inducer/vent to the pressure switch, allowing it to prove safe draft before ignition. Cracked, brittle, clogged, or disconnected tubing is a frequent cause of pressure-switch-open lockouts — replacing it is an inexpensive fix that restores reliable startup.

Specifications

OEM Part Number: A3468601
Part Type: Pressure Switch Tubing / Hose
Inside Diameter: 3/16"
Fits: AMH80905CNAB and compatible Goodman/Amana furnaces
Function: Transmits draft pressure signal to the pressure switch
Equipment: Gas Furnace

OEM vs. Generic

The OEM tubing is sized to the exact 3/16" ID and heat-rated material Goodman specifies, so it seals tightly on the switch and inducer ports without kinking or splitting. Generic hose can be the wrong durometer or diameter, leaking the pressure signal. OEM guarantees an airtight, warranty-safe connection.

Installation Difficulty

Very Easy (1/5) — Power off, pull the old hose off both ports, and press on the new tubing. A 5-minute repair and one of the cheapest fixes for pressure-switch faults.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80905CNAB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80905CNAB — 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 AMH80905CNAB — 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.
