There could be may causes for this. You have eliminated the technician and maybe the control board. The frig won’t cool if the freezer does not. So forget the frig thermistor or control. Not making any noise means the compressor is stopped. The compressor will stop if the freezer gets down to temp or the control thinks it is there. That would indicate a bad sensor or connection, or control. The compressor may also stop if there is a problem in the compressor system like too high or too low a pressure. Resetting by unplugging right after the compressor stops would result in it not restarting until a 3-5 min timeout has passed. All AC systems do this because the compressor cannot overcome the line pressure on startup and it would burn out the compressor motor. If it restarts immediately, you may still have a control board issue.
