Rick O Milwaukee , WI May 09, 2015 Appliance: Samsung Refrigerator RS2555SW/XAA Samsung Refrigerator Rs2555sw/Xaa / : Warm refridgerator/freezer compressor hot not running. How to replace Capacitor. Removed lower rear cover, compressor was very hot. This is usually a capacitor issue, but the schematic on the back of the unit shows a start/ run relay. For the low cost, I replaced both. parts were delivered in 2 days. The start/ run relay is mounted directly to the compressor. It slides on/ off with a little bit of prying. No fasteners. The start capacitor is inside a white plastic housing on the lower right corner of the unit. Phillips screwdriver is all you need to complete the job. I was worried that the compressor may have been damaged (the compressor was hot for hours after being unplugged) but it works perfectly now. 25 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
