The Goodman A3468601 Pressure Switch Tubing is the genuine OEM 3/16-inch ID hose that connects the draft-inducer pressure tap to the pressure switch on the Goodman/Amana AMH80703AXCB furnace. This small-bore tube carries the negative-pressure (draft) signal that proves the inducer is running before the control board allows ignition. Cracked, brittle, or clogged tubing is a common cause of pressure-switch faults and ignition lockouts.

Specifications

  • OEM Part Number: A3468601
  • Part Type: Pressure switch sensing tubing / hose
  • Inside Diameter: 3/16 inch
  • Material: High-temperature silicone, resistant to heat and condensate
  • Compatibility: Goodman & Amana AMH80703AXCB and related 80% AFUE models

OEM vs. Generic

OEM silicone tubing is rated for the heat and moisture of the flue-draft environment and matches the exact ID for a tight, leak-free push-fit onto the switch and inducer barbs. Generic vinyl tubing hardens and cracks over time, reintroducing the same intermittent no-heat symptoms.

Installation Difficulty

Easy. Power off, pull the old hose from both barbs, cut the new tubing to length, and press it on. Inspect the pressure port for soot or condensate blockage while it is off.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80703AXCB — A3468601?
Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80703AXCB — 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 AMH80703AXCB — 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.
