OEM Goodman 0259F00018 12-Pin Wiring Harness

The genuine Goodman/Amana 0259F00018 is a 12-pin wiring harness built for the AMH81405DNAC gas furnace and compatible Goodman/Amana models. This harness carries low-voltage and control signals between the integrated furnace control board and connected components. Melted, chafed, or rodent-damaged harnesses cause intermittent faults, no-heat conditions, and hard-to-diagnose control errors. Replacing with the correct OEM harness guarantees the right connector, pinout, and wire gauge for a reliable repair.

Connector: 12-pin OEM plug
Application: Control board / component interconnect
Wire: Manufacturer-spec gauge and color coding
Fits: AMH81405DNAC and compatible Goodman/Amana furnaces
OEM Part #: 0259F00018

OEM vs. Generic

There is no reliable universal substitute for a multi-pin control harness — connector keying and pin order must match the board exactly. This OEM Goodman harness plugs directly into the AMH8 control without splicing, re-pinning, or guesswork, eliminating the miswire risk that comes with building a harness by hand.

Installation Difficulty: Moderate

Disconnect power, photograph the existing connections, unplug the keyed connector(s), and route the new harness along the same path away from hot surfaces. Basic electrical familiarity is recommended; confirm every plug is fully seated before restoring power. Allow 30–45 minutes.
