OEM Goodman A3468601 Pressure Switch Tubing (3/16" ID)

The Goodman A3468601 is genuine OEM 3/16-inch inner-diameter tubing that connects the draft-inducer pressure tap to the furnace pressure switch on AMH81405DNAC gas furnaces. This small hose carries the negative-pressure signal that proves adequate venting before the burners fire — a cracked, kinked, or hardened hose is a common cause of nuisance pressure-switch lockouts. It fits Goodman and Amana models built on the same platform.

Category: Pressure Switch Tubing
OEM Part Number: A3468601
Inner Diameter: 3/16 inch
Fits: AMH81405DNAC and compatible Goodman/Amana furnaces
Function: Draft/pressure sensing signal line

OEM vs. Generic

Genuine OEM tubing uses the correct 3/16" bore and heat-rated material so it seals tightly on the pressure-switch and inducer barbs. Undersized or oversized generic hose can leak the pressure signal, causing false lockouts. At this price, OEM is the obvious choice.

Installation Difficulty

Easy — pull the old hose off both barb fittings and push the new length on. No tools required; verify routing avoids hot surfaces and sharp kinks.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH81405DNAC — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH81405DNAC — 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 AMH81405DNAC — 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.
