Goodman B1225020 Low-Voltage Wiring Harness

The B1225020 is a genuine Goodman OEM wiring harness built for the ASH130481AC 13 SEER, 4-ton heat pump. It carries low-voltage signal and power between the control board, contactor, reversing-valve solenoid, and sensors using color-coded conductors and factory-crimped connectors. Brittle insulation, chafed wires, or corroded terminals cause intermittent faults and no-cool/no-heat calls — a fresh OEM harness eliminates the guesswork and restores reliable connections.

Specifications

OEM Part Number: B1225020
Fits: Goodman ASH130481AC heat pump
Type: Low-voltage control wiring harness
Connectors: Factory-terminated, keyed plugs
Conductors: Color-coded, insulated
Equipment: Heat Pump (outdoor condenser)

OEM vs. Generic

The genuine Goodman harness arrives pre-terminated with the correct connector bodies and wire gauge, so it plugs straight in with no splicing. Generic bulk wire forces you to cut, crimp, and match pin-outs by hand — a common source of miswires and callbacks. OEM guarantees the right length and keyed fit every time.

Installation Difficulty: Easy

Rated Easy (2/5). Cut power at the disconnect, photograph the existing routing, unplug the old harness, and seat the new connectors until they click. Basic hand tools only; no refrigerant or brazing needed.
