Freezer had completely defrosted and refrigerator was not cooling. Took about 1.5 hours to diagnose and 30 minutes to fix. Evaporator fan, both lights, and freezer to refrigerator transfer fan were all running. Compressor and condenser fan were not running. No power to compressor or condenser fan. Power to the freezer thermostat but not out of freezer thermostat. Replaced freezer thermostat.
