This plug-in harness carries low-voltage control and sensor signals between the unit's control board, defrost board, and field connections through a keyed 16-position connector. Replacing a chafed, melted, or corroded harness restores reliable communication and eliminates intermittent faults caused by broken conductors or backed-out terminals.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 16-pin low-voltage control wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e Keyed 16-position plug (factory pinout)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductors:\u003c\/strong\u003e Color-coded, pre-terminated leads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Control\/defrost board interconnect and sensor circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e APH1536M41AB package heat pump control system\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM B1378700 comes pre-terminated with the correct pin assignments, wire gauge, and connector keying, so it plugs straight in with no rewiring.

Disconnect power, photograph the routing, unplug the 16-pin connector at each end, release any retaining clips, and route the new harness along the original path. Straightforward for a technician; care is needed to seat both connectors fully and keep leads clear of the fan and hot surfaces.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058286608755,"sku":"GOODMAN-15574","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-16-pin-wiring-harness-for-aph1536m41ab-heat-pump-b1378700","provider":"National HVAC Parts","version":"1.0","type":"link"}
