Goodman A3468601 3/16" ID Pressure Switch Tubing

This genuine Goodman A3468601 pressure-switch tubing has a 3/16-inch inner diameter and connects the inducer draft port to the furnace pressure switch on the DMS81155CNA and compatible Goodman/Amana furnaces. The tube transmits the negative pressure signal that proves the inducer is moving combustion air before the board allows ignition. Cracked, brittle, or clogged tubing produces false pressure-switch lockouts and no-heat calls — fresh OEM tubing restores reliable draft sensing.

Specifications

  • OEM Part Number: A3468601
  • Inner Diameter: 3/16 inch
  • Material: Heat-resistant silicone/rubber tubing
  • Function: Pressure switch signal line
  • Fits: Goodman DMS81155CNA and compatible models

OEM vs. Generic

OEM tubing is cut to the correct ID and length and rated for furnace-cabinet heat. Generic hose may have wrong bore size or lower heat tolerance, leading to false trips or premature hardening. OEM keeps the draft signal accurate.

Install Difficulty

Easy — Slide off the old tube at both barbs and press on the new one. No tools required. Confirm no kinks and a snug fit at each connection.
