Goodman A3468601 3/16" ID Pressure Switch Tubing

The A3468601 is genuine Goodman 3/16-inch inside-diameter pressure-switch tubing that connects the inducer collector box or vent to the draft pressure switch. It is a direct-fit replacement for the AMS81405DXA gas furnace and is common across many Goodman and Amana induced-draft furnaces. Cracked, brittle, or condensate-blocked hose is a leading cause of nuisance pressure-switch lockouts and open-switch no-heat codes.

Specifications

Type: Pressure switch sensing tube / hose
Inside Diameter: 3/16 inch
OEM Part Number: A3468601
Primary Fit: Goodman AMS81405DXA furnace
Material: Heat- and condensate-resistant silicone/rubber
Brand: Goodman / Amana OEM

OEM vs. Generic

OEM tubing is rated for the furnace's flue temperatures and resists hardening near the inducer. Generic hardware-store hose can soften, kink, or dry out quickly, producing false pressure faults. OEM keeps the sensing signal accurate through the heating season.

Installation Difficulty

Easy (1 of 5). Power down the furnace, pull the old hose off both barbed fittings, cut the new tubing to match, and press it fully onto each port with no kinks or sags that trap condensate. Under 10 minutes with no tools required.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMS81405DXA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMS81405DXA — 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 AMS81405DXA — 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.
