Goodman A3468601 Pressure Switch Tubing (3/16" ID)

The Goodman A3468601 is genuine OEM 3/16-inch inside-diameter pressure switch tubing for the Amana/Goodman AMS80905CNAA 80% AFUE gas furnace. This flexible hose connects the pressure switch to the inducer/vent tap so the switch can sense negative pressure (draft) and prove airflow before the furnace allows ignition. Cracked, brittle, or clogged tubing is a frequent cause of a pressure-switch fault and no-heat lockout.

Specifications

Part number: A3468601
Inside diameter: 3/16 inch
Type: Pressure/draft sensing tubing (silicone/high-temp)
Fits: AMS80905CNAA and compatible Goodman/Amana furnaces
Heat- and moisture-resistant for combustion-area service

OEM vs. Generic

This genuine OEM tubing is cut to the correct length and rated for the temperature and condensate exposure near the inducer. Generic vinyl hose can harden, kink, or split under furnace heat, leading to false pressure-switch trips. The OEM hose ensures the switch reads true system pressure.

Installation Difficulty

Very Easy (1/5). A 5-minute repair: power off the furnace, pull the old tube from both barb fittings, and press the new tube fully onto each fitting with no kinks or sags that could trap condensate. Confirm the switch closes on a call for heat and the furnace lights normally.

Compatible with Amana and Goodman furnaces. Verify your model and part number before ordering.

Does this Pressure Switch fit my Goodman AMS80905CNAA — A3468601?

How do I replace the pressure switch on my Goodman AMS80905CNAA — 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.
