The Goodman A3468601 is genuine OEM 3/16" ID pressure switch tubing for the AMH80704BXCB gas furnace. This small-diameter hose carries the pressure signal between the inducer/collector box and the furnace's pressure (draft) switch. A clean, flexible, correctly-sized tube is essential for accurate draft sensing — if the tubing cracks, kinks, or fills with condensate, the pressure switch may fail to close and the furnace will lock out before ignition.

Specifications

Type: Pressure switch signal tubing
Inside diameter: 3/16"
Material: Flexible high-temperature hose
Function: Connects inducer/collector to pressure switch
Brand fit: Goodman & Amana furnaces
OEM Part #: A3468601

OEM vs. Generic

OEM A3468601 tubing is rated for furnace heat and holds its 3/16" bore without collapsing, so the pressure signal reaches the switch reliably. Generic hardware-store tubing can soften, kink, or use a slightly off ID that leaks at the barbs, causing intermittent no-heat lockouts. For a trouble-free repair, use the factory-spec hose.

Installation

Difficulty: Easy. This is one of the simplest furnace repairs — most homeowners can do it in under 10 minutes. Power down the furnace, pull the old tube off both barb fittings, and press the new tubing fully onto each barb, routing it with no low spots where condensate can pool. Trim to length if needed. If the furnace still trips on pressure switch after replacement, inspect the inducer and vent for blockage.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80704BXCB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80704BXCB — 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 AMH80704BXCB — 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.
