Quick check — and when it's not DIY
The one self-check that's actually worth your time: listen for the evaporator fan running when the door's closed, since a silent fan is a common first sign. If it's still acting up after that, it's usually a defrost heater, sensor, or sealed-system fault, and diagnosing those needs a multimeter and refrigeration training, not guesswork.
