The fan breaks or operates based on the 24V signal traveling through the low-voltage harness (blue\/yellow lines). If the motor is sitting dead but you measure a consistent 24V call from the board during cooling mode, the internal electronic control module on the motor has failed and the assembly must be replaced.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference \u0026amp; Compatibility:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e The 51-102728-07 is a direct premium OEM replacement for the following components:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e RP51-102728-07, 51-102728-10, 51-102728-21\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAftermarket\/Genteq:\u003c\/strong\u003e GE Genteq X13 Series, Broad-Ocean Variable Equivalents (Verify programming)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRheem Premium Heat Pumps:\u003c\/strong\u003e RPRL-024-JEC, RPRL-024-JEZ, RPRL-025-JEC, RPRL-036-JEC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRuud Ultra Series Heat Pumps:\u003c\/strong\u003e RPRL-036-JEZ, RPRL-037-JEC, RPRL-048-JEC, RPRL-048-JEZ\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRheem\/Ruud Select Line:\u003c\/strong\u003e RPRL-049-JEC, RPRL-060-JEC, RPRL-060-JEZ, RPRL-061-JEC, RQPM-A037\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rheem","offers":[{"title":"Default Title","offer_id":53217582678379,"sku":"0662766398892","price":895.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/51-102728-07.jpg?v=1778614244","url":"https:\/\/tophvacparts.com\/products\/rheem-protech%e2%84%a2-51-102728-07-motor-ecm-outdoor-1-3-hp-208-230v","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
