This harness carries low-voltage signals between the integrated furnace control board, gas valve, limit switches, and blower circuit. A cracked connector, chafed wire, or melted pin from a heat event can cause intermittent lockouts, no-heat calls, or failed ignition sequences — replacing the harness restores clean, reliable connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0259F00018\u003c\/li\u003e\n\u003cli\u003eConnector: 12-pin keyed plug\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMH80704BNAA furnace\u003c\/li\u003e\n\u003cli\u003eFunction: Control board to component low-voltage harness\u003c\/li\u003e\n\u003cli\u003eType: Direct-fit factory replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM harness\u003c\/strong\u003e uses factory-spec connectors and gauge wiring that match the AMH80704BNAA control board pinout exactly — no splicing, no guesswork.
