This factory-terminated harness carries low-voltage control and sensor signals between the control board and the unit's components through a keyed 16-position connector. Melted pins, corroded terminals, or chewed insulation lead to intermittent faults, no-heat\/no-cool calls, and erratic board behavior — a fresh OEM harness clears all of it.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378700\u003c\/li\u003e\n\u003cli\u003eCompatible Model: APH1630M41AB\u003c\/li\u003e\n\u003cli\u003eEquipment Type: Heat Pump\u003c\/li\u003e\n\u003cli\u003eConnector: 16-pin keyed, factory-crimped terminals\u003c\/li\u003e\n\u003cli\u003eFunction: Low-voltage control \/ sensor interconnect\u003c\/li\u003e\n\u003cli\u003eFit: Plug-and-play — matches OEM connector keying and pinout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eControl harnesses are only as reliable as their crimps and pin alignment. This genuine Goodman harness uses factory-spec terminals and the correct 16-pin keying, so it seats fully and locks the first time. Hand-built or generic harnesses risk mis-pinned circuits and loose crimps that cause the exact intermittent faults you are trying to fix. OEM guarantees the pinout matches the board.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eRating: Easy.\u003c\/strong\u003e With power disconnected, unplug the old harness at both keyed connectors, route the new harness along the original path, and click it into place — the keying prevents backwards installation. No stripping, crimping, or refrigerant work required.
