Goodman A3468601 Pressure Switch Tubing (3/16" ID)

The Goodman A3468601 is genuine OEM 3/16-inch inside-diameter tubing that connects the pressure switch to the inducer draft port on DHS80905CXA and compatible Goodman/Amana furnaces. This hose carries the negative-pressure signal that proves the inducer is drawing combustion products through the heat exchanger. Cracked, brittle, or blocked tubing causes intermittent no-heat lockouts and pressure-switch fault codes.

Specifications

Part number: A3468601
Inside diameter: 3/16"
Material: High-temperature silicone/rubber
Function: Draft pressure signal line
Fits: Goodman/Amana DHS80905CXA and related furnaces

OEM vs. Generic

OEM tubing is cut to the correct length and rated for the furnace's flue temperatures and condensate exposure. Generic vinyl hose can harden and crack prematurely near the inducer. For a reliable draft-proving signal, OEM silicone is the safer choice.

Install Difficulty

Easy — Power off, pull the old hose from both barbed fittings, and press on the replacement. Confirm there are no kinks or trapped condensate. A quick DIY-friendly repair.

Frequently Asked Questions

Does this Pressure Switch Hose fit my Goodman DHS80905CXA — A3468601?

Yes. This is the factory-specified OEM pressure switch hose for the Goodman DHS80905CXA — 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 hose on my Goodman DHS80905CXA — 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 hose 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 hose?

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.
