Goodman A3468601 3/16" ID Pressure Switch Tubing

The A3468601 is genuine OEM 3/16-inch inside-diameter pressure switch tubing for the Goodman/Amana AMH80603ANBB gas furnace and compatible models. This hose connects the draft-inducer/vent assembly to the pressure switch, transmitting the negative pressure signal that proves proper venting before the burners are allowed to light. Cracked, brittle, kinked, or blocked tubing is a frequent cause of pressure-switch faults and ignition lockouts on aging furnaces.

Specifications

OEM Part Number: A3468601
Inside Diameter: 3/16 inch
Fits: Amana/Goodman AMH80603ANBB and compatible furnaces
Application: Draft-inducer to pressure-switch signal line
Type: Direct-fit factory replacement tubing

OEM vs. Generic

The genuine OEM tubing is the correct 3/16" ID, wall thickness, and heat-rated material for reliable draft sensing near the inducer. Generic tubing of the wrong bore or lower temperature rating can collapse, harden, or leak, producing intermittent pressure-switch trips. The OEM A3468601 restores factory sensing accuracy.

Installation Difficulty

Very Easy (1/5). Slip the new tubing onto the inducer and pressure-switch ports, routing it without kinks or low spots that could trap condensate. Shut off power and gas before servicing, and confirm the pressure switch closes on a normal start cycle afterward.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80603ANBB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80603ANBB — 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 AMH80603ANBB — 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.
