This harness carries control and power signals between the unit's main control board and its components through a single keyed 16-position connector. Melted pins, corroded terminals, or brittle insulation cause intermittent faults, error codes, and no-heat\/no-cool conditions — a fresh OEM harness restores clean, reliable connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378700\u003c\/li\u003e\n\u003cli\u003eConnector: 16-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\u003ePre-terminated, factory-crimped leads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine OEM harness arrives pre-crimped with the correct wire gauge, color coding, and connector keying for your board.
