Goodman A3468601 Pressure Switch Tubing

This genuine OEM Goodman A3468601 pressure switch tubing is the exact 3/16" inner-diameter hose used to connect the draft pressure switch to the inducer housing on the Goodman DMS80905CNA gas furnace and many compatible Goodman/Amana models. When the original tubing hardens, cracks, or collapses, the pressure switch can no longer read inducer draft accurately, causing intermittent lockouts and no-heat calls. Replacing it restores reliable pressure sensing and safe furnace operation.

Specifications

Inner diameter: 3/16 inch
Material: heat-resistant silicone/rubber tubing
Application: pressure switch to inducer draft sensing line
Fits: Goodman DMS80905CNA and compatible 80% furnaces
OEM Part Number: A3468601

OEM vs. Generic

Genuine OEM tubing is rated for the high-temperature, near-flue environment inside the furnace cabinet and holds its flexibility far longer than generic vinyl hose. Bargain tubing often stiffens and cracks within a season, leading to nuisance pressure-switch faults. This OEM part is the correct bore and length for a clean, leak-free press fit.

Installation Difficulty

Easy — a 5-minute repair for most homeowners. Cut power at the furnace switch, note the routing of the old hose, slide it off both barbs, and press the new tubing on. No tools or special skills required. If you are unsure, consult a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman DMS80905CNA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman DMS80905CNA — 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 DMS80905CNA — 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.
