Goodman A3468601 3/16" ID Pressure Switch Tubing

The Goodman A3468601 is genuine OEM 3/16-inch inside-diameter pressure switch tubing for the DHS80453AXA gas furnace and compatible Goodman/Amana models. This flexible hose carries the negative-pressure (draft) signal from the inducer housing or vent to the pressure switch, which proves proper venting before allowing ignition. Cracked, brittle, or clogged tubing is a leading cause of a furnace that ignites and immediately shuts off or throws a pressure-switch fault.

Specifications

OEM Part Number: A3468601
Inside Diameter: 3/16 inch
Type: Flexible pressure/draft signal tubing (hose)
Function: Connects inducer/vent port to the pressure switch
Fits: Goodman DHS80453AXA and select Goodman/Amana furnaces

OEM vs. Generic

Genuine Goodman tubing is sized and rated for furnace flue-gas heat and holds a stable seal on the switch and inducer ports so the pressure signal reads true. Generic tubing may soften, kink, or leak, producing false pressure-switch trips. For a reliable safety signal, OEM is recommended.

Installation Difficulty

Easy — A quick 5–10 minute repair. Shut off power, pull the old tube off both barb fittings, cut the new tubing to the same length, and press it firmly onto the inducer port and pressure switch. Confirm no kinks and a snug fit at each end.

Route the tubing so it drains any condensate and avoids sagging loops. If pressure-switch faults persist after replacement, have the inducer and venting inspected by a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman DHS80453AXA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman DHS80453AXA — 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 DHS80453AXA — 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.
