Goodman 0259F00018 12-Pin Wiring Harness

The Goodman 0259F00018 is a genuine OEM 12-pin wiring harness built for the AMH80905CNAC gas furnace. It carries low- and line-voltage connections between the integrated furnace control board and key components such as the gas valve, blower, and safety switches. A melted, chafed, or corroded harness can cause intermittent faults, blower problems, or complete no-start conditions.

Specifications

Connector: 12-pin control-board plug
Pre-terminated, color-coded conductors
Factory pin-out matched to Goodman/Amana ignition control
Heat-resistant insulation rated for furnace cabinet temperatures
Direct OEM replacement, part number 0259F00018

OEM vs. Generic

There is no true universal substitute for a molded 12-pin harness. This OEM Goodman harness is wired to the exact factory pin map for the AMH80905CNAC, eliminating the guesswork and mis-wiring risk of building a repair harness from loose leads.

Install Difficulty

Moderate (3/5) — The plug is keyed, but routing the harness and reconnecting individual component leads takes care. Photograph existing connections before removal, cut power first, and verify each terminal seats fully. Professional installation is recommended for anyone not comfortable tracing furnace wiring.
