The Goodman A3468601 3/16 inch ID Pressure Switch Tubing is a genuine OEM silicone hose that connects the pressure switch to the inducer draft port on Goodman/Amana AMS80904BNA gas furnaces. This tubing carries the negative-pressure signal the switch uses to confirm proper venting before ignition. Cracked, brittle, or clogged tubing is a leading cause of a furnace that clicks but won't light and a flashing pressure-switch fault code.

  • Part number: A3468601
  • Inside diameter: 3/16 inch
  • Material: High-temperature silicone
  • Function: Draft pressure signal line to pressure switch
  • Fits: Goodman/Amana AMS80904BNA and compatible furnace models

OEM vs. Generic: OEM silicone tubing is rated for the heat and vacuum near the inducer and resists hardening far longer than generic vinyl hose. Off-spec ID sizes can slip off the port or leak, causing false lockouts. OEM guarantees a snug seal and correct pressure reading.

Install difficulty: Easy (1/5). Pull the old hose off both ports and push the new length on — no tools required. Under 10 minutes. Route away from hot surfaces and confirm the switch closes on a call for heat.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMS80904BNA — A3468601?
Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMS80904BNA — 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 AMS80904BNA — 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.
