The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16" ID hose that connects the pressure switch to the inducer/collector box on the AMH80905CXAA 80% gas furnace and related Goodman/Amana models. This tubing carries the pressure signal that lets the furnace confirm proper venting draft before the burners ignite.

Specifications

Part type: Pressure switch tubing / hose
Inner diameter: 3/16"
OEM part number: A3468601
Compatible model: AMH80905CXAA (80% gas furnace)
Brand family: Goodman / Amana

OEM vs. Generic

Cracked, hardened, or clogged tubing is a common cause of pressure-switch lockout faults. The OEM A3468601 is cut to the correct length and made from heat-resistant silicone rated for furnace service. Generic vinyl tubing can harden and split near hot components, causing intermittent no-heat calls.

Install Difficulty

Very Easy — a push-on hose replacement that takes minutes. Power down the furnace, note the routing, and slip the new hose onto the same ports.
