The Goodman A3468601 Pressure Switch Tubing is the genuine OEM 3/16-inch ID draft hose for the AMH81155CNAC furnace. This small silicone line connects the pressure switch to the inducer/vent port and lets the switch sense proper draft before the burners are allowed to fire. A cracked, hardened, or clogged hose is a common cause of pressure-switch lockout faults.

Specifications

Inside diameter: 3/16 inch
Function: Pressure switch sensing/vacuum tube
Material: Heat-resistant silicone tubing
Fits: Goodman/Amana AMH81155CNAC furnaces
Brand: Goodman OEM (A3468601)

OEM vs. Generic

The OEM tube is pre-cut to the correct length and rated for furnace flue temperatures. The generic equivalent is the same 3/16in silicone by the foot at a lower price — trim to length yourself.

Installation Difficulty

Easy. Slip the old hose off both ports and press the new one on. Plan 5 minutes; no tools required.

Cut power before servicing and confirm the hose routes without kinks.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH81155CNAC — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH81155CNAC — 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 AMH81155CNAC — 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.
