Genuine Goodman 3/16" ID Pressure Switch Tubing A3468601

Keep your Goodman/Amana AMH81155CXAA furnace sensing draft correctly with this OEM 3/16-inch inside-diameter pressure switch tubing. This flexible hose connects the induced-draft pressure switch to the inducer housing or vent tap, transmitting the negative pressure the switch reads to confirm safe venting before the burners fire. Cracked, brittle, or clogged tubing causes pressure-switch faults and lockouts — replacing it is one of the cheapest, most common furnace repairs.

Specifications

OEM Part Number: A3468601
Inside Diameter: 3/16 inch
Fits: Goodman & Amana AMH81155CXAA and compatible furnaces
Material: High-temperature silicone/rubber hose
Flexible for tight cabinet routing
Resists heat, condensate, and vibration fatigue

OEM vs. Generic

The OEM hose has the exact 3/16" bore and wall thickness needed for an accurate pressure signal and a snug fit on the switch and inducer ports. Generic tubing in the wrong bore can leak vacuum or kink, producing false pressure-switch trips. At this price, there's no reason not to use the correct part.

Installation Difficulty

Very Easy (1/5). Power off, slide the old hose off both ports, cut the new tubing to the same length, and push it firmly onto each fitting. Under 5 minutes and no tools required.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH81155CXAA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH81155CXAA — 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 AMH81155CXAA — 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.
