Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is a genuine OEM 5-pin wiring harness designed for the Goodman/Amana APH1630H41AC heat pump. This compact harness connects a sub-assembly — such as a sensor, switch, or motor lead group — to the unit's control circuit via a keyed 5-pin plug. Damaged pins, brittle insulation, or a loose connector on this circuit can trigger nuisance lockouts and inconsistent operation; the exact OEM harness restores a clean, reliable connection.

Specifications

  • Part type: Wiring harness / control sub-connector
  • Connector: 5-pin keyed plug (plug-and-play)
  • Fits model: APH1630H41AC (16 SEER heat pump)
  • Conductors: Color-coded, factory-terminated leads
  • Brand compatibility: Goodman & Amana OEM assemblies

OEM vs. Generic

The OEM B1378701 ships with the correct keyed 5-pin housing pre-terminated to spec, dropping straight into place. Generic pigtails require crimping and pin-mapping that can be reversed or loose — the factory harness removes that risk entirely.

Installation

Difficulty: Easy. A quick plug-and-play swap — kill power, unclip the old 5-pin connector, and snap in the replacement, matching the keyed orientation. Typically under 15 minutes. Confirm power is off at the disconnect first.

Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this wiring harness compatible with Bryant or Payne too?
