The Goodman A3468601 is genuine OEM 3/16 inch ID pressure switch tubing, a direct-fit replacement for the Goodman/Amana AMH80453AXAA gas furnace and compatible models. This hose connects the pressure switch to the inducer draft port, allowing the switch to sense negative pressure and confirm proper venting before the furnace fires.

Cracked, brittle, or clogged tubing is a common cause of pressure-switch faults and no-heat lockouts. Replacing the tubing with the correct OEM part restores an accurate pressure signal and reliable ignition.

Specifications

Inside diameter: 3/16 inch
Function: Pressure switch sensing line
Fits: Goodman/Amana AMH80453AXAA and compatible furnaces
Type: Direct-fit OEM replacement
Material: Heat-resistant flexible tubing

OEM vs. Generic

The genuine Goodman A3468601 uses the correct 3/16 in bore and heat-rated material so it seals tightly on the switch and inducer ports without kinking. Generic tubing may be the wrong diameter or degrade quickly near the heat exchanger. At this price, OEM is the easy, dependable choice.

Installation Difficulty

Easy. Power off the furnace, pull the old tubing from the pressure switch and inducer ports, cut the new tubing to the same length, and press it firmly onto both ports. No special tools required — a beginner-friendly repair.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80453AXAA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80453AXAA — 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 AMH80453AXAA — 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.
