It carries low-voltage control and sensor signals between the unit control board and its components through a single keyed connector, so replacement is a clean plug-and-play job. Melted pins, chafed insulation, corroded terminals, or a harness damaged by rodents or heat can trigger intermittent faults, no-heat\/no-cool calls, and error codes — a new OEM harness eliminates that failure point.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1378700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e 16-pin control wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e Keyed 16-position plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e APH1624M41AB (and select Goodman\/Amana heat pumps)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire:\u003c\/strong\u003e Color-coded, factory-terminated leads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eUniversal harnesses require cutting, splicing, and re-pinning, which introduces resistance and moisture-intrusion points that fail again.

Disconnect power at the breaker, unplug the old harness at both ends, route the new one along the original path, and click the connectors home. Roughly 20–40 minutes with basic tools. Verify all power is off before opening the control panel.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058294964595,"sku":"GOODMAN-15781","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-16-pin-wiring-harness-for-aph1624m41ab-b1378700","provider":"National HVAC Parts","version":"1.0","type":"link"}
