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

The Goodman A3468601 is genuine OEM 3/16 inch inside-diameter pressure switch tubing, a direct replacement for the Goodman/Amana AMH80704BXAA furnace and compatible models. This hose connects the induced-draft blower's pressure tap to the furnace's pressure switch, allowing the switch to confirm proper venting airflow before the ignition sequence begins. Cracked, brittle, kinked, or condensate-blocked tubing is a very common cause of a pressure-switch lockout and a furnace that will not fire.

Specifications

OEM Part Number: A3468601
Inside Diameter: 3/16 in.
Fits: Goodman / Amana AMH80704BXAA and compatible furnaces
Type: Pressure/draft sensing tube
Material: High-temperature silicone/rubber tubing

OEM vs. Generic

The OEM tubing is the factory-original hose in the correct 3/16" ID and heat rating for a reliable, leak-free seal. Our Generic equivalent matches the diameter and temperature spec at a lower price. Either restores accurate draft sensing and dependable ignition.

Install Difficulty: Easy (1/5)

One of the simplest furnace repairs — about 5 minutes. Cut power, pull the old tube off the switch and draft-inducer barbs, cut the new tubing to match the original length, and press it firmly onto both fittings. Ensure no kinks or low spots that could trap condensate. Always disconnect power before servicing.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80704BXAA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80704BXAA — 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 AMH80704BXAA — 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.
