The Goodman A3468601 Pressure Switch Tubing is genuine OEM 3/16" ID hose for the draft-proving circuit on the Amana/Goodman AMH80703AXCA 80% AFUE gas furnace. This tubing carries the negative-pressure signal from the inducer collector box or vent to the pressure switch, allowing the control board to confirm proper venting before energizing the gas valve.

  • OEM Part Number: A3468601
  • Category: Pressure Switch Tubing
  • Inside Diameter: 3/16 inch
  • Compatible Model: AMH80703AXCA (80% AFUE furnace)
  • Brand: Goodman / Amana
  • Application: Draft / pressure-switch sensing line

OEM vs. Generic: Cracked, brittle, or clogged sensing tubing is a frequent cause of pressure-switch lockouts and no-heat calls. The OEM A3468601 is the correct 3/16" ID heat-resistant tubing that seals tightly on the switch and inducer ports, delivering an accurate pressure signal. Generic vinyl tubing can harden and leak, producing false open-switch faults.

Install Difficulty: Easy. Slide the new tubing onto the pressure-switch and inducer ports, ensuring no kinks or condensate traps. Shut off power first and route the line so moisture cannot pool inside it.

Restore a reliable draft-proving signal with the genuine Goodman A3468601 pressure switch tubing.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman AMH80703AXCA — A3468601?
Yes. This is the factory-specified OEM pressure switch for the Goodman AMH80703AXCA — 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 AMH80703AXCA — 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.
