Brian R Chesterfield , MO February 14, 2015 Appliance: Kenmore Side By Side Refrigerator 10650503990 Kenmore Refrigerator 10650503990: No cool compressor would not start fan and lights running. How to replace Capacitor. First replaced start capacitor but that did not work, the start kit which has a relay and overload protector is what was needed. The relay is actually the only part that was bad I believe. After pulling the relay off the compressor you could shake it and it rattled, the new one did not. Really pretty easy and definitely cheaper than a service call. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
