Goodman 0259F00018 12-Pin Wiring Harness

The Goodman 0259F00018 is a genuine OEM 12-pin wiring harness built as a direct replacement for the Goodman/Amana AMH80704BXAA furnace and compatible models. This harness carries low-voltage and control signals between the integrated furnace control board and the furnace's components. Melted terminals, brittle insulation, or intermittent connections at the main plug are a frequent cause of no-heat calls, error codes, and intermittent blower or ignition behavior — a factory-terminated replacement harness restores clean, reliable connections.

Specifications

OEM Part Number: 0259F00018
Connector: 12-pin molded plug
Fits: Goodman / Amana AMH80704BXAA and compatible furnaces
Type: Pre-terminated low-voltage control harness
Wire: Color-coded, high-temperature insulated leads

OEM vs. Generic

The OEM harness is the factory-original assembly with exact pin-out and connector keying for a guaranteed fit. Our Generic equivalent replicates the pin layout and wire gauge at a lower cost. We recommend OEM for control-board wiring where correct keying and terminal quality are critical.

Install Difficulty: Moderate (3/5)

Straightforward for anyone comfortable tracing furnace wiring. Photograph the existing connections first, cut all power, then unplug and route the new harness following the same path. Confirm the 12-pin connector is fully seated and latched before restoring power. If you're unsure of routing, consult the furnace wiring diagram or a licensed HVAC technician.
