The Goodman 0259F00009P is a genuine OEM 15-pin female wiring harness built for the GMTH090-5 furnace and equivalent Goodman/Amana equipment. It serves as the mating half to the 15-pin male connector, completing the low-voltage control path between the furnace control board and downstream safety and ignition components.

If you're seeing intermittent operation, error codes, or a loose/burnt connector, replacing both harness halves ensures clean, positive contact across all 15 circuits.

Part Number: 0259F00009P
Connector Type: 15-pin, female
Fits: Goodman GMTH090-5 furnace
Application: Control board / low-voltage circuit
Pairs With: 0259F00008P male harness

OEM vs. Generic: Genuine Goodman female harnesses deliver factory pin tension and locking geometry that generic parts frequently miss. A poor-fitting aftermarket connector can back out under thermal cycling and cause hard-to-diagnose intermittent faults. OEM is strongly recommended for control-circuit reliability.

Installation Difficulty: Moderate — suitable for experienced DIYers. Cut power at the breaker, document the existing wiring with a photo, and confirm the connector clicks fully into its locking tab. When in doubt, use a licensed HVAC technician.
