The Goodman B1378701 5-Pin Wiring Harness is a genuine OEM replacement designed specifically for the APH1630H41AB packaged heat pump. This pre-terminated harness delivers the exact plug geometry, wire gauge, and connector pinout the unit's control circuit expects, eliminating the guesswork and splice failures common with universal wiring.

Over time, exposure to heat, vibration, and moisture can crack insulation or corrode the pins on the original harness, causing intermittent operation, nuisance faults, or a no-start condition. Dropping in a factory-matched harness restores clean, low-resistance connections between the board and its downstream components.

Specifications

OEM Part Number: B1378701
Connector: 5-pin keyed plug
Fits: Goodman/Amana APH1630H41AB heat pump
Type: Pre-terminated control wiring harness
Brand: Goodman (OEM)

OEM vs. Generic

The OEM harness guarantees correct pin orientation and wire color coding, so it lands in place without modification and preserves your equipment warranty. A generic harness may cost slightly less but often requires cutting, crimping, and re-pinning, introducing failure points and troubleshooting headaches. For a control-circuit part, OEM is the smart choice.

Installation Difficulty

Easy (1/5). Disconnect power, unplug the old harness, route and seat the new one into the matching connectors. Basic hand tools only. Always confirm power is off at the disconnect before servicing.
