The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16" ID hose that connects the pressure switch to the inducer/collector on the Amana/Goodman AMH81005CXBA gas furnace. This tubing carries the negative draft signal the pressure switch needs to prove the inducer is pulling proper airflow before allowing ignition. Cracked, hardened, or clogged tubing causes the switch to read a false pressure fault — resulting in a furnace that won't light or that locks out on a pressure-switch error.

Specifications

Part Number: A3468601
Inside Diameter: 3/16"
Type: High-temperature pressure/draft sensing tube
Fits: AMH81005CXBA and compatible Goodman/Amana furnaces
Equipment: 80% AFUE gas furnace
Material: Heat-resistant silicone/rubber tubing

OEM vs. Generic

The OEM Goodman hose is the correct 3/16" ID and heat-rated length, so it seats fully on both barbs without kinking. Generic tubing of the wrong bore or wall thickness can leak signal pressure or collapse under vacuum, mimicking a bad pressure switch. Inexpensive to replace and worth doing whenever you service the switch.

Install Difficulty

Very Easy (1/5). Pull the old tube off both barb fittings, press the new one fully onto each, and confirm no kinks. Under 5 minutes, no tools required.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH81005CXBA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH81005CXBA — 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 AMH81005CXBA — 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.
