The Goodman A3468601 is a genuine OEM 3/16" inner-diameter pressure switch tubing designed for the AMV80703BXA gas furnace and compatible Goodman/Amana models. This flexible silicone hose connects the inducer draft port to the pressure switch, allowing the switch to accurately sense combustion airflow before the furnace is permitted to ignite. Cracked, brittle, or disconnected tubing is one of the most common causes of pressure-switch lockout faults.

  • Inner diameter: 3/16 inch
  • Material: high-temperature silicone
  • Function: draft/combustion airflow sensing line
  • OEM part number: A3468601
  • Fits: AMV80703BXA and compatible Goodman & Amana furnaces

OEM vs. Generic: Genuine OEM tubing is rated for the exact temperature and vacuum tolerances of your furnace, resisting the heat-hardening that causes generic hose to crack prematurely. Generic silicone tubing costs less but may not seal reliably at the switch barb, leading to nuisance lockouts.

Install difficulty: Easy (1/5). Slide the old hose off both barbs and press the new tubing fully onto each fitting. No tools required. Always shut off power and gas before servicing.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMV80703BXA — A3468601?
Yes. This is the factory-specified OEM pressure switch for the Goodman AMV80703BXA — 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 on my Goodman AMV80703BXA — 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 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?
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.
