A weakened capacitor is the #1 cause of premature motor failure. Always verify the MFD rating on the 51-104940-01 label (typically 7.5 or 10 MFD) and install a brand-new run capacitor at the same time to validate your warranty and ensure a cool-running motor.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e 51-104940-01, 51-24373-21, 51-23012-41\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAftermarket\/Fasco:\u003c\/strong\u003e D727 (Verify specs), Mars 10585\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eModel Compatibility:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRheem\/Ruud Classic Series:\u003c\/strong\u003e RGRM, RGRA, RGLQ, RGLE, RGLN, RGLT\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRheem\/Ruud Criterion:\u003c\/strong\u003e RGPH, RGLH, RGVH\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWeatherKing:\u003c\/strong\u003e 80PJ, 80PS, 90RJ, 90RS\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rheem","offers":[{"title":"Default Title","offer_id":53211806630251,"sku":"662766545968","price":658.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/51-104940-01.jpg?v=1778521452","url":"https:\/\/tophvacparts.com\/products\/rheem-protech%e2%84%a2-51-104940-01-blower-motor-genuine-oem-1-2-hp-120v-1075-rpm-4-speed","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
