The Goodman B1378701 5-Pin Wiring Harness is a genuine OEM connector harness engineered as a direct-fit replacement for the APH1530M41AA package heat pump and compatible Goodman/Amana equipment. This 5-pin harness links a specific subsystem — such as a sensor group, blower, or defrost circuit — to the unit's control board. Pre-terminated with the factory connector and correct pin-out, it delivers a fast, reliable repair when the original harness is damaged, corroded, or causing intermittent operation.

Specifications

Part Number: B1378701
Type: Control wiring harness
Connector: 5-pin OEM plug
Fits: Goodman/Amana APH1530M41AA and related heat pump models
Function: Low-voltage signal and control connection
Construction: Color-coded, factory-terminated leads with locking connector

OEM vs. Generic

Because this OEM harness carries the exact 5-pin connector, wire gauge, and pin layout your system was designed around, it plugs straight in with no rewiring. A generic or hand-built substitute invites pin-out mistakes and loose connections that trigger hard-to-trace control faults. The factory part guarantees a correct, secure fit the first time.

Install Difficulty

Difficulty: Moderate. With power disconnected at the breaker, note the original routing, unplug the old harness, and connect the replacement in its place. No refrigerant handling is needed, but proper connector seating and orientation are essential. When in doubt about low-voltage wiring, use a licensed HVAC technician.

Get your APH1530M41AA communicating reliably again with the genuine Goodman B1378701 5-pin harness.
