This prevents rainwater from running down the wires and bypassing the seals. Additionally, verify that the fan blade is positioned at the correct depth within the shroud to ensure maximum heat rejection and to prevent the motor from over-amping.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCross-Reference \u0026amp; Compatibility:\u003c\/strong\u003e The 51-102870-08 is a direct OEM replacement for the following part numbers: \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e 51-102870-08, 51-101870-08, 51-102500-08\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLegacy Ref:\u003c\/strong\u003e 5SME39SXL062, 5SME39SL0001\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRheem Prestige Series:\u003c\/strong\u003e RA17, RA20, RP17, RP20\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRuud Ultra Series:\u003c\/strong\u003e UA17, UA20, UP17, UP20\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSpecific Units:\u003c\/strong\u003e RA1748AJ2CB, RP1760AJ2VC, RA2024AJ2VC, RP2036AJ2VC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rheem","offers":[{"title":"Default Title","offer_id":53191499284843,"sku":"0662766620153","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/51-102870-08.jpg?v=1778185455","url":"https:\/\/tophvacparts.com\/products\/rheem-protech%e2%84%a2-51-102870-08-genuine-oem-outdoor-variable-speed-ecm-condenser-fan-motor-1-3-hp-208-230v","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
