The temperature in the freezing compartment of my side-by-side refrigerator freezer has been gradually rising over the past week to (presently) 30 degrees; while the temperature in the refrigerator is also gradually rising. The coils are (amazingly) clean and are warm--nearly hot--to the touch. Both the internal and condenser-coil fans are operative. Early forums submissions seemingly indicate the replacement of the compressor run capacitor (AP4315853). Correct, or are there other viable options?

I, most certainly, do not dispute your advice; however (today), I replaced the compressor run capacitor, with the result that the temperature in the freezer is presently 0 degrees and, in the refrigerator, 37 degrees. I don't care what the reason is: I'm overjoyed, because (at least for the moment), my 23-year-old refrigerator operates as I wish. Thank you, Kind Sir, for your advice--which may yet become useful, but (for the present), I'm not going to ". . . fix what ain't broke."
