This smaller harness links a specific subassembly — such as a sensor, motor, or switch circuit — to the control board through a keyed 5-position connector. When pins overheat, terminals corrode, or a lead breaks, the affected component drops offline and can trip fault codes. Replacing the harness with the correct OEM part restores a solid, weather-tight connection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378701\u003c\/li\u003e\n\u003cli\u003eConnector: 5-pin keyed plug\u003c\/li\u003e\n\u003cli\u003eCompatible Model: APH1624H41AA\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eEquipment: Packaged Heat Pump\u003c\/li\u003e\n\u003cli\u003eFactory-crimped, color-coded leads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1378701 ships pre-terminated with the exact connector keying and wire gauge your unit expects, so it plugs in without splicing.
