The Goodman A3468601 is genuine OEM 3/16-inch inside-diameter pressure switch tubing for the AMH80804BXBB gas furnace. This flexible hose carries the negative-pressure signal from the inducer/collector box to the pressure switch, allowing the furnace control to confirm proper venting before ignition. Cracked, brittle, kinked, or clogged tubing is one of the most common causes of a furnace that locks out on the pressure switch or short-cycles — a fresh length of correct-bore tubing restores a clean draft-proving signal.

Specifications

Inside Diameter: 3/16 in
Type: Pressure switch sensing tubing / hose
Brand: Goodman / Amana (OEM)

OEM vs. Generic

The genuine OEM A3468601 uses the exact 3/16" bore and heat-resistant material specified for the AMH80804BXBB draft-sensing circuit. Generic tubing in the wrong diameter or a softer compound can collapse under vacuum, leak air, or degrade near the inducer heat, throwing false pressure faults. For an accurate, stable pressure signal, match the OEM spec.

Installation Difficulty

Rating: Easy. Slip the old hose off both barbed fittings, cut the new tubing to the same length, and press it firmly onto each port. No tools or calibration required. Shut off power before servicing.

Fit verified for your model. In stock and ready to ship.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80804BXBB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80804BXBB — 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 AMH80804BXBB — 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.
