dynamic appliance repair Upon receiving a call about a Subzero built-in refrigerator that wasn't cooling, I began by inspecting the appliance's condenser coils for any signs of dirt or debris. I then checked the thermostat settings to ensure they were correctly configured. After confirming the settings, I accessed the refrigerator's control board to diagnose any potential electrical issues. I discovered a malfunctioning compressor, which was the root cause of the cooling problem. I replaced the faulty compressor and tested the refrigerator to ensure it was cooling properly. The refrigerator now operates efficiently, maintaining the desired temperature.
