The Goodman 0259F00007P 12-Pin Wiring Harness is a genuine OEM replacement connector assembly engineered for GDS80703AXA gas furnaces and compatible Goodman/Amana models. This harness carries low-voltage control and sensor signals between the integrated furnace control board and its downstream components. A cracked, melted, or corroded harness is a common cause of intermittent no-heat calls, error codes, and blower faults — replacing it with the correct OEM part restores reliable, spec-matched connectivity.

Specifications

OEM Part Number: 0259F00007P
Connector: 12-pin
Brand: Goodman (fits Amana equivalents)
Equipment: Gas Furnace
Primary Fit: GDS80703AXA
Type: Low-voltage control harness

OEM vs. Generic

This is a factory OEM harness with molded, keyed connectors and correctly gauged conductors that match the furnace control board pinout exactly. Generic or hand-spliced alternatives risk pin misalignment, intermittent contact, and voided warranty coverage. For a safety-critical gas appliance, we recommend the OEM harness.

Installation Difficulty

Easy (2/5). Disconnect power at the service switch, unplug the failed harness from the control board, route the replacement along the same path, and seat each keyed connector until it clicks. No wiring modifications required. If you are not comfortable working inside a gas furnace, contact a licensed HVAC technician.
