This three-stage, 110-120 volt motor replaces the 117939 only. If your current motor is stamped 7939 or 11-7939, that is the same motor under a shortened marking.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 110-120 V, 50-60 Hz | \u003cstrong\u003eAmps:\u003c\/strong\u003e 13.6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan stages:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt height:\u003c\/strong\u003e 3-1\/2\" | \u003cstrong\u003eOverall height:\u003c\/strong\u003e 8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir watts:\u003c\/strong\u003e 458 | \u003cstrong\u003eCFM:\u003c\/strong\u003e 101.2 | \u003cstrong\u003eWaterlift:\u003c\/strong\u003e 138.6\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottom diameter:\u003c\/strong\u003e 5.7\"\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWorking life is roughly 900-1,200 hours. Time to replace when you see any of these: a mini breaker that keeps popping, an electrical odor, excessive blue sparking from the motor top, or a motor that dies and then runs again later. No click at all when the vacuum is switched on usually implicates the relay, not the motor. Installation involves a few screw brackets and basic wiring. Two 117939 carbon motor brushes will service the brush set when it wears.\u003c\/p\u003e","brand":"MD Central Vacuum","offers":[{"title":"Default Title","offer_id":50024899117306,"sku":"199R","price":162.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0684\/3934\/3354\/files\/3880a3e9bd48fc3d325fe84ab15ec9df.jpg?v=1786161947","url":"https:\/\/evacuumsandmore.com\/products\/lamb-ametek-117939-central-vacuum-motor-3-stage","provider":"Vacuums and More","version":"1.0","type":"link"}
