The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16" inner-diameter hose engineered for the AMH80903BXCB furnace and compatible Goodman and Amana models. This tubing connects the pressure switch to the inducer or collector box, carrying the vacuum signal that proves proper venting airflow before the furnace allows ignition. Cracked, brittle, or clogged tubing is a leading cause of no-heat and pressure-switch lockout faults.

Specifications

OEM Part Number: A3468601
Inner Diameter: 3/16"
Type: Pressure switch signal tubing / hose
Material: High-temperature silicone
Fits model: AMH80903BXCB and select Goodman/Amana furnaces
Brand: Goodman (Daikin family)

OEM vs. Generic

The OEM Goodman tubing is rated for the temperature and flexibility your furnace requires, holding a reliable vacuum seal at both ends. Generic hardware-store hose can be too stiff, wrong diameter, or unrated for heat — leading to poor sealing, false pressure faults, and premature cracking.

Installation Difficulty

Easy (1 of 5). Simply pull the old hose off both barbed fittings and press the new tubing fully onto each. Takes under 10 minutes. Shut off power before servicing and confirm no kinks or pinches in the routing.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80903BXCB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80903BXCB — 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 AMH80903BXCB — 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.
