The Goodman A3468601 is a genuine OEM 3/16 in. inner-diameter pressure switch tubing (hose) engineered for the Goodman GMT140-5A gas furnace and other compatible Goodman/Amana models. This flexible high-temperature silicone hose carries the reference pressure signal between the inducer housing and the pressure switch, allowing the control board to confirm safe venting before the burners fire. Cracked, brittle, or collapsed tubing is one of the most common causes of nuisance lockouts and "open pressure switch" fault codes.

Specifications

Inner diameter: 3/16 in.
Material: high-temperature silicone rubber
Application: draft/pressure switch signal line
Fits: Goodman GMT140-5A and compatible Goodman & Amana furnaces
OEM part number: A3468601

OEM vs. Generic

The genuine Goodman A3468601 is molded from furnace-rated silicone that resists heat aging and will not harden or split like generic vinyl tubing. Aftermarket hose is cheaper up front but often shrinks or cracks within a season, forcing a repeat repair. For a reliable, code-compliant fix, the OEM hose is the right call.

Installation Difficulty

Easy — a slip-on repair most homeowners can complete in minutes with power off. Simply pull the old hose off both barbed fittings and press the new tubing fully onto each port. No tools required.

Always disconnect power before servicing your furnace. If you are unsure, consult a licensed HVAC technician.

Frequently Asked Questions

Does this Pressure Switch Hose fit my Goodman GMT140-5A — A3468601?

Yes. This is the factory-specified OEM pressure switch hose for the Goodman GMT140-5A — 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 hose on my Goodman GMT140-5A — 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 hose 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 hose?

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.
