Clicking sound then within a minute clicking again, not cooling.

UNPLUG REFRIGERATOR. Carefully remove relay from the side of the compressor. You shouldn't need a tool to do this, if it is hard you can gently pry the edge with a flat head screw driver just to loosen. Unplug white and red wires from relay, noting that the white wire goes in the hole with a #2 stamped beside it. Shake old relay, if it rattles like a baby rattler then it's most likely the problem. Replace wires into the new relay and plug back into the compressor.
