Mike S Durham , NC May 03, 2017 Appliance: Samsung Refrigerator RS2577SL/XAA Samsung Refrigerator Rs2577sl/Xaa: Side by side samsung would not cool and compressor was not coming on. How to replace Refrigerator Compressor Overload Relay. ** DISCONNECTED POWER FIRST* I pulled off start relay, and the overload located attached to the side of the compressor. Checked OHMS on 3 pins on compressor. Got continuity through all 3- and NO reading by touching the pins and any copper tubing ,,,compressor was good. Probable cause was start relay or overload- Could of metered both to rule out which one-but neither were too expensive, so opted to replace both rather that doing one and then the other go out 2-3 months later. Pluged unit back in , and the compressor powered up. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
