Goodman B1225020 Wiring Harness

The Goodman B1225020 is a genuine OEM wiring harness engineered for the ASZ130301AC 13 SEER, 2.5-ton (30,000 BTU) heat pump condenser and compatible Goodman/Amana units. This pre-terminated harness carries the control and low-voltage connections between the defrost board, contactor, sensors, and terminal block, with factory-crimped connectors and correct wire gauge and color coding. Replacing a burned, chewed, corroded, or brittle harness restores reliable connections and eliminates intermittent faults caused by loose or damaged wiring.

Specifications

  • Part number: B1225020
  • Type: Pre-terminated control / low-voltage wiring harness
  • Connectors: Factory-crimped, color-coded leads
  • Fits: Goodman ASZ130301AC and compatible heat pumps
  • Application: Control-board to component interconnect

OEM vs. Generic

The OEM harness is molded and terminated to plug directly into the ASZ130301AC's board and components — no splicing, no guesswork. Building a harness from generic wire risks wrong gauge, poor crimps, and mismatched connectors that lead to voltage drop, arcing, or shorts. For factory-correct connections, the OEM harness installs cleanly and safely.

Installation Difficulty

Moderate (3/5). Photograph and label all connections first. Disconnect power at the breaker, unplug the old harness one connector at a time, and route the replacement identically. If unsure of routing, consult the unit's wiring diagram or an HVAC technician.

Always disconnect power before servicing HVAC equipment.
