The Goodman A3468601 Pressure Switch Tubing is genuine OEM 3/16-inch ID hose for ADS81155CNA furnaces and compatible Goodman/Amana models. This flexible tube connects the inducer/collector box to the draft pressure switch, carrying the negative-pressure signal that proves proper venting before the burners ignite. Cracked, brittle, or clogged tubing is a frequent cause of pressure-switch lockouts and no-heat calls.

Specifications

Type: Pressure switch signal tubing
Inside diameter: 3/16 inch
OEM Part Number: A3468601
Brand: Goodman
Application: Inducer-to-pressure-switch draft line
Compatible model: ADS81155CNA

OEM vs. Generic

This factory-original Goodman tubing is sized to the exact 3/16" ID and material spec needed for a clean, leak-free pressure signal. Generic hose with the wrong diameter or wall thickness can slip off the nipples or collapse, producing false pressure-switch faults. An inexpensive, high-value part to replace during any furnace tune-up.

Installation Difficulty

Easy — slip the tube onto the inducer and pressure-switch ports; trim to length if needed. Inspect for condensate blockage and a snug fit. Disconnect power before servicing.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman ADS81155CNA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman ADS81155CNA — 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 ADS81155CNA — 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.
