The Goodman B1378700 is a genuine OEM 16-pin wiring harness engineered for the APH1536M41BA packaged heat pump. This factory-terminated harness carries the low-voltage control signals between the unit's control board, defrost board, and sensor circuits. Because it is a direct OEM assembly, every pin is keyed and color-coded to match the original connector, eliminating the guesswork and miswiring risk that comes with cutting and splicing a universal cable.

Specifications

Part Number: B1378700
Connector Type: 16-pin, keyed OEM plug
Application: Goodman/Amana APH1536M41BA heat pump
Circuit: Low-voltage control & defrost signaling
Brand: Goodman (Genuine OEM)

OEM vs. Generic

A generic patch cable forces you to identify each conductor, crimp new terminals, and hope the pin-out matches. The OEM B1378700 arrives pre-terminated and keyed, so it seats in one orientation and passes UL-rated control voltage exactly as the factory intended. For a control harness, OEM is the safer choice — a single reversed conductor can damage the control board.

Installation Difficulty

Easy (1/5). Disconnect power at the breaker, unplug the old harness, route the new B1378700 along the same path, and click both connectors home. No tools beyond a screwdriver for the panel are required. Verify connector clips are fully latched before restoring power.

Compatible with APH1536M41BA. Confirm your model and part number before ordering.
