Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is a factory 5-pin wiring harness engineered for the APH1560M41CA heat pump and compatible Goodman/Amana air-source systems. This harness carries low-voltage control and sensor signals between the unit's control board and its connected components, ensuring reliable communication and safe operation. Cracked insulation, corroded pins, or a melted connector can cause intermittent faults, error codes, or a no-run condition — a direct-fit replacement restores clean, secure connections in minutes.

Part number: B1378701
Connector: 5-pin keyed plug
Type: Low-voltage control/sensor harness
Fits: Goodman APH1560M41CA heat pump
Equipment: Air-source heat pump
Material: Heat- and abrasion-resistant insulated leads

OEM vs. Generic

Choosing the genuine Goodman OEM harness guarantees the exact pin count, keying, wire gauge, and lead lengths specified for your unit — a universal generic harness often requires splicing or re-pinning and can introduce resistance or loose connections. The OEM part plugs in and works, protecting your board and sensors from wiring faults.

Installation Difficulty

Easy (1/5). Disconnect power at the breaker, unplug the old harness at both ends, route the new harness along the original path, and click the keyed connectors into place. No special tools required. Always verify power is off before servicing; if you are unsure, consult a licensed HVAC technician.
