Genuine OEM Goodman A3468601 Pressure Switch Tubing is a 3/16" inner-diameter hose that connects the inducer/collector box to the furnace pressure switch on the Amana/Goodman AMV81155CXBA. This tubing carries the negative-pressure signal that proves the inducer is pulling proper draft before the burners fire. Cracked, brittle, or clogged tubing is a common cause of "pressure switch open" lockouts and no-heat calls.

  • OEM Part #: A3468601
  • Inner Diameter: 3/16"
  • Fits: Amana/Goodman AMV81155CXBA and compatible furnaces
  • Function: Draft/pressure signal line to the pressure switch
  • Material: High-temp silicone/rubber tubing

OEM vs. Generic: The OEM tubing is rated for the furnace's flue-area temperatures and cut to fit factory port sizes, so it stays flexible and leak-free over time. Bargain tubing can harden or collapse near heat, leading to intermittent pressure-switch faults.

Install difficulty: Very easy (DIY-friendly, 5–10 min). Power off, pull the old hose from both barbed ports, and press the new tubing fully onto each fitting. Confirm there are no kinks or sags where condensate could collect.
