Goodman B1225020 Wiring Harness

The Goodman B1225020 is a genuine OEM wiring harness assembled for the ASZ130301AB heat pump. This pre-terminated harness delivers the factory-correct connections between the control board, contactor, capacitor, and field terminals, with the right gauge wire, insulation rating, and connector types already crimped in place. Replacing a burned, brittle, or rodent-damaged harness with the OEM part eliminates guesswork and the risk of miswiring during a repair.

Specifications

  • OEM Part Number: B1225020
  • Compatible Model: ASZ130301AB (Heat Pump)
  • Type: Pre-terminated control wiring harness
  • Connectors: Factory-crimped push-on and molded plugs
  • Insulation: High-temperature rated for condenser use
  • Routing: Matched to Goodman control box layout

OEM vs. Generic

The B1225020 arrives with every connector in the correct position and every lead cut to length, so it drops into the ASZ130301AB exactly as the original did. Building a harness from bulk wire and spade terminals invites polarity mistakes, loose crimps, and heat-related failures. The OEM harness ensures correct terminations and preserves equipment warranty.

Installation

Difficulty: Moderate. With power disconnected, photograph the existing connections, unplug the old harness one lead at a time, and transfer the new harness connector-for-connector — roughly 30–45 minutes. Working methodically prevents crossed leads. A licensed technician is recommended if you are not confident tracing control wiring.

Restore clean, factory-correct wiring with genuine Goodman parts. Order the B1225020 harness today.
