Goodman A3468601 Pressure Switch Tubing (3/16-inch ID)

The A3468601 is genuine Goodman/Amana 3/16-inch inside-diameter pressure switch tubing for the AMH80704BXCA 80% AFUE gas furnace and other compatible models. This small hose connects the induced-draft pressure switch to the collector box or inducer port, allowing the switch to sense negative pressure and confirm proper venting before the furnace ignites. Cracked, hardened, or clogged tubing is one of the most common and inexpensive causes of a furnace that will not light.

Specifications

Part number: A3468601
Inside diameter: 3/16 inch
Type: OEM pressure/draft sensing tubing
Material: Heat-resistant silicone-style hose
Fits: Goodman & Amana gas furnaces including AMH80704BXCA

OEM vs. Generic

This OEM tubing is manufactured in the correct diameter and heat-rated compound so it stays flexible and leak-free near hot furnace components. Generic vinyl tubing may be the wrong bore size or harden and crack under heat, causing intermittent pressure-switch faults. For reliable draft sensing, the OEM hose is the right call.

Installation Difficulty: Easy

Replacement takes just a few minutes: power down the furnace, pull the old tubing off both barbed ports, cut the new tubing to matching length, and press it firmly onto each port. No tools are typically required. Confirm there are no kinks and that both ends are fully seated, then verify the furnace fires normally.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80704BXCA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80704BXCA — 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 AMH80704BXCA — 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.
