Goodman A3468601 Pressure Switch Tubing

The Goodman A3468601 is a genuine OEM 3/16-inch inner-diameter pressure switch tubing designed as a direct-fit replacement for the AMH80403AXBA gas furnace. This flexible hose connects the pressure switch to the inducer assembly or collector box, allowing the switch to sense negative pressure and confirm proper venting before the burners fire. Cracked, hardened, or disconnected tubing is one of the most common causes of a furnace that ignites and then shuts down on a pressure-switch fault.

Specifications

Part Number: A3468601
Inner Diameter: 3/16 inch
Component: Pressure switch sensing tube
Fits: Goodman/Amana AMH80403AXBA furnace
Material: High-temperature silicone/rubber hose
Type: OEM exact-fit replacement

OEM vs. Generic

Our genuine OEM A3468601 is cut and rated to the exact temperature and diameter spec of your Goodman furnace, so it seats tightly on the port barbs without leaks. Generic bulk tubing may vary in wall thickness and heat rating, risking false pressure-switch trips and nuisance lockouts. For a reliable seal, OEM is the safe choice.

Install Difficulty: Easy

A basic DIY repair. Power down the furnace, slip the old tubing off both barb fittings, route the new hose along the same path, and press it firmly onto each port. No tools required. Estimated time: 5-10 minutes.

How do I replace the pressure switch on my Goodman AMH80403AXBA — 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.

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?
