Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is a genuine OEM 5-pin low-voltage wiring harness engineered for AEPT030-00C-1A air handlers and compatible Goodman/Amana models. This harness carries the control signals between the air handler control board and its blower and accessory circuits, using a keyed 5-position connector that mates only one way to prevent miswiring. When the original harness becomes brittle, corroded, or intermittent, replacing it with the factory part restores reliable communication and eliminates nuisance no-heat / no-cool faults.

Specifications

Part Number: B1378701 (OEM Goodman)
Connector: 5-pin keyed, low-voltage
Application: Air handler control wiring
Fitment: AEPT030-00C-1A and compatible Goodman/Amana air handlers
Material: Color-coded stranded copper with factory terminals

OEM vs. Generic

Choosing the genuine Goodman B1378701 guarantees correct connector keying, wire gauge, and terminal crimps. Generic universal harnesses often require cutting and splicing, introduce resistance at hand-made connections, and can void labor warranties. The OEM harness is plug-and-play — no rewiring, no guesswork.

Installation Difficulty

Easy (1/5). Disconnect power, unplug the old harness at both ends, route the new harness along the same path, and reconnect. Most technicians complete this in under 15 minutes. Always shut off power at the disconnect before servicing.
