GE Refrigerator Freezer not cooling

Both the refrigerator and freezer in my GE PFS22SISBSS have stopped cooling, and a loud clicking sound is coming from the compressor or overload release. Lights and temperature readouts are working, the compressor fan is clean and running, and the evaporator fan runs as well. Diagnostic checks on the main board J2 connector voltage all check out as well. Any suggestions?
