The Goodman A3468601 Pressure Switch Tubing is genuine OEM 3/16-inch inside-diameter hose designed for the AMH80904BNAA furnace and other compatible Goodman and Amana models. This tubing connects the inducer/collector box to the furnace pressure switch, transmitting the vacuum signal the control board uses to confirm safe combustion airflow before allowing ignition. Cracked, hardened, or disconnected tubing is a leading cause of pressure-switch lockout faults.

Specifications

Inside Diameter: 3/16 in.
Type: Pressure switch sensing tube
Fits Model: AMH80904BNAA
Brand: Goodman / Amana (OEM)

OEM vs. Generic

Genuine A3468601 tubing is rated for the heat and vacuum conditions inside a furnace cabinet, resisting the hardening and cracking that cause intermittent no-heat calls. Generic hose may be under-rated for temperature or the wrong ID, leading to leaks and false pressure-switch trips. OEM ensures an accurate, reliable draft signal.

Installation

Difficulty: Easy (1 of 5). Simply route the new hose between the pressure switch and inducer port, trimming to length; no tools required. Power off the furnace first and confirm the switch closes on a call for heat.

My furnace shows a pressure switch error. What do I replace?

Should I use OEM or aftermarket for my Goodman pressure switch?
