I've had a similar problem twice, it's all related to the thermostat. The worst thing that can happen in these cases is to jam the compressor from overheating, so the refrigerator should definitely be turned off before a technician arrives. I solved my problem quickly because I know where to go. I use Ae Factory Service to repair any home appliances. If you are out of options and need urgent repairs, you can check out and contact this service center. They promptly dispatch a repair technician who quickly diagnoses and fixes the problem with a warranty.
