The Goodman 0259F00009P Wiring Harness is a genuine OEM 15-pin female connector assembly for the Goodman GMT140-5A gas furnace and compatible Goodman/Amana models. It mates with the 15-pin male harness to complete the signal and power path between the furnace control board and its components. Worn or corroded female terminals cause intermittent connections, blower or ignition faults, and hard-to-trace no-heat calls — this factory harness restores a reliable, keyed link.

Specifications

Connector: 15-pin, female
OEM Part Number: 0259F00009P
Type: Pre-terminated wiring harness assembly
Compatible Model: Goodman GMT140-5A furnace
Mates with: 15-pin male harness (0259F00008P)
Brand: Goodman (Amana compatible)

OEM vs. Generic

The OEM 0259F00009P delivers the precise terminal spacing and keying needed to seat cleanly against the male harness. We do not recommend generic substitutes for keyed 15-pin furnace connectors — mispinning risks shorts and board failure. Genuine OEM is the safe, first-time-fit choice.

Installation Difficulty

Moderate (3 of 5). Plug-in replacement that still requires matching to the mating male harness and verifying routing and seating. Document the original configuration before removal. Disconnect power before working inside the furnace; use a licensed technician if you're uncertain.
