This OEM Goodman A3468601 pressure switch tubing is a genuine replacement hose engineered for the Amana/Goodman AMH80803BNBB gas furnace. The 3/16-inch inside-diameter tubing connects the inducer draft pressure taps to the pressure switch, carrying the small vacuum signal that proves proper venting airflow before the burners ignite. A cracked, brittle, or clogged hose is one of the most common causes of a furnace that starts and then locks out on a pressure-switch fault.

Specifications

Inside diameter: 3/16 inch
Application: pressure switch / inducer draft signal line
Fits: Amana & Goodman AMH80803BNBB and compatible 80,000 BTU furnaces
OEM Part Number: A3468601
Material: high-temperature silicone-grade tubing

OEM vs. Generic

Genuine OEM tubing is formulated to resist the heat and condensate exposure found near the inducer assembly, holding its seal and flexibility far longer than generic vinyl hose. Undersized or low-temp aftermarket tubing can collapse under vacuum or harden and crack, producing intermittent lockouts that are difficult to diagnose. For a reliable repair we recommend the OEM part.

Install Difficulty: Easy

A basic 10-minute repair. Shut off power and gas, slide the old hose off both barbed fittings, and press the new length on until fully seated. No tools required beyond a utility knife to trim to length. Always confirm the switch clicks over on a call for heat after replacement.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80803BNBB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80803BNBB — 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 AMH80803BNBB — 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.
