Goodman A3468601 Pressure Switch Tubing is genuine OEM 3/16-inch ID hose used to route the draft-sensing signal on the Goodman/Amana AMH80905CXCA 80% AFUE gas furnace and related models. This small-diameter tube connects the induced-draft blower (or collector box) to the pressure switch, allowing the switch to sense negative pressure and prove that the inducer is moving air before the burners are allowed to ignite. Cracked, brittle, or blocked tubing is a frequent cause of pressure-switch lockouts and ignition faults.

Specifications

OEM Part Number: A3468601
Component Type: Pressure switch / draft-sensing tubing
Inner Diameter: 3/16 inch
Material: Heat- and moisture-resistant tubing
Fits: Goodman & Amana AMH80905CXCA and compatible furnaces

OEM vs. Generic

The OEM A3468601 tubing is the correct 3/16in ID and rated for the temperature and condensate exposure it sees on the draft circuit. Generic hardware-store hose may be the wrong bore (leaking the signal) or degrade quickly in the furnace environment, leading to repeat failures. Using the factory part ensures a proper seal and reliable pressure sensing.

Installation Difficulty

Easy — A 5-minute job. Power down the furnace, slip the old tube off both barbed fittings, cut the replacement to match, and press it onto the inducer port and pressure switch. Confirm no kinks. Test for proper ignition sequence afterward.

An inexpensive part that prevents nuisance lockouts. Genuine OEM tubing, ships fast.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80905CXCA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80905CXCA — 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 AMH80905CXCA — 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.
