Goodman B1378700 16-Pin Wiring Harness

The Goodman B1378700 is a genuine OEM 16-pin wiring harness built for the Goodman/Amana APH1630H41AC heat pump. This multi-conductor harness carries the low-voltage control and sensor signals between the main control board and the unit's components. Chafed insulation, melted connectors, or corroded pins can cause intermittent faults, error codes, and no-run conditions — swapping in the correct OEM harness eliminates the guesswork of chasing individual wires.

Specifications

  • Part type: Multi-pin wiring harness / control connector
  • Connector: 16-pin keyed plug (plug-and-play)
  • Fits model: APH1630H41AC (16 SEER heat pump)
  • Conductors: Color-coded, factory-terminated leads
  • Brand compatibility: Goodman & Amana OEM boards

OEM vs. Generic

The OEM B1378700 arrives pre-terminated with the correct keyed 16-pin housing, so it plugs directly into the board with no crimping or pin-out cross-referencing. Building a harness from generic wire and connectors invites mis-pinning and connection failures — the factory harness is the fast, foolproof fix.

Installation

Difficulty: Moderate. Requires disconnecting power, photographing routing, and unplugging/re-plugging the keyed connector while noting cable dress. Comfortable DIYers can manage it; if the harness ties into multiple components, a qualified HVAC tech is recommended. De-energize the unit before servicing.
