Goodman A3468601 3/16 in. ID Pressure Switch Tubing

The Goodman A3468601 is genuine OEM 3/16-inch inside-diameter pressure switch tubing for the AMH80403AXBB gas furnace and compatible Goodman/Amana models. This flexible hose connects the draft-inducer pressure tap to the furnace's pressure switch, letting the switch sense negative draft pressure and confirm the venting system is clear before the burners fire. Cracked, brittle, or clogged tubing causes false pressure-switch faults and no-heat lockouts.

Specifications

OEM Part Number: A3468601
Type: Pressure switch sensing tube / hose
Inside Diameter: 3/16 inch
Brand: Goodman (Daikin family)
Compatibility: AMH80403AXBB and select Goodman/Amana furnaces
Application: Draft-pressure signal between inducer and switch

OEM vs. Generic

OEM tubing is molded from heat-resistant material sized to the exact port fitting for a snug, leak-free connection. Generic tubing can be the wrong durometer or ID, slipping off the ports or collapsing under heat. For dependable draft sensing, OEM is recommended.

Installation Difficulty

Easy. A quick DIY repair — slide the old tube off both ports and press the new one on, routing it clear of hot surfaces. Shut off power and gas first, and clear any moisture or blockage from the pressure tap.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80403AXBB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80403AXBB — 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 AMH80403AXBB — 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.
