Goodman A3468601 Pressure Switch Tubing (3/16 in. ID)

The Goodman A3468601 is genuine OEM 3/16 inch inside-diameter pressure-switch tubing for the AMH80453ANAA furnace. This hose connects the draft-inducer or vent tap to the furnace pressure switch, carrying the sensing signal that proves proper venting before the burners fire. Cracked, brittle, or clogged tubing is one of the most common causes of a furnace that ignites and then shuts down on a pressure-switch fault.

Specifications

Type: Pressure switch sensing tubing
Inside diameter: 3/16 in.
Material: Heat-resistant silicone/rubber hose
Fit: Direct OEM replacement
Compatible model: AMH80453ANAA (Goodman/Amana furnace)
OEM Part No.: A3468601

OEM vs. Generic

The OEM A3468601 uses the correct 3/16 in. ID and high-temperature material rated for continuous furnace-cabinet heat. Generic aquarium-grade tubing may fit loosely, harden quickly, or leak vacuum, leading to nuisance lockouts. For a reliable draft-proving circuit, OEM tubing is the low-cost, high-value choice.

Installation Difficulty

Easy — Pull the old hose from both barbed fittings and press on the new length, matching routing so it doesn't kink or contact hot surfaces. About 10 minutes. Disconnect power first.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80453ANAA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80453ANAA — 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 AMH80453ANAA — 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.
