Fridge & Freezer temp 10+ deg too high

Multiple repair calls under extended contract. Power supply, controller board, three thermistors all replaced. Set Freezer to -5, fridge to 33. Fridge barely manages 42, freezer maybe 20. Last repair guy said it’s working normally. Guess he likes to drink his ice cream. I keep remote reading temp sensors in both. I see what looks like reasonable temp cycles, just too high. Fans both work. Compressor doesn’t sound hard to start. Just removed cover on fridge evap to clear the drain. Evap temp was around 10 with a little frost.
About ready to trash this thing. Wife LOVES the LED lighting (Replaced three of those already.) We keep important stuff (meds) in $100 dorm fridge in the garage, which works great.
