Vito S North Olmstead , OH March 13, 2016 Clicking sound but no cooling I located the Overload relay attached to the compressor. Easily removed by prying with a screw driver. Test the black capacitor with a meter set on DC volts. You should be able to watch the voltage drop as it discharges . A replacement arrived in 2 days. I plugged it in and the refrigerator now cools.
