Good add. Also check the evaporator side: open the freezer hold the door switch, and make sure the evaporator fan runs and there isn’t a thick frost sheet on the back panel. If a full manual defrost (unplug 12–24 hours, doors open) makes it cool well for a few days then fade again, you’re likely looking at a defrost system issue (timer/heater/thermostat) rather than airflow at the back. While it’s running, the condenser coils should feel warm and the compressor should gently vibrate; if the coils stay cool, a bad start relay is the cheap first fix.
