Problem began with freezer temperature increasing (room temperature), which was shortly followed (less than a week) with refrigerator temperature increase (slightly less than room temperature). I have researched many articles and have cleaned the coil, verified condenser fan is turning, and compressor is warm (not hot). I did look at the main circuit board and didn't see any visible damage (i.e., burns). After unplugging and plugging the refrigerator, I do hear a couple of noticeable clicks and a sound like the compressor is charging the system and then one more click, but it seems to come from a location lower than the main circuit board (center right as you're looking at the board). What is the logical next step and most likely cause. Any assistance would be greatly appreciated.
