If a mini fridge and freezer stop working every few weeks but start working again after being unplugged for a few hours, it could indicate a few possible issues:
Overheating: The refrigerator's compressor or other components may be overheating, causing it to shut down temporarily. When you unplug the unit, it allows time for the components to cool down and reset. However, the underlying cause of the overheating needs to be addressed to prevent future failures.
Electrical Issues: There might be a problem with the electrical supply or the power cord of the mini fridge. It could be a loose connection, a faulty power cord, or even an issue with the electrical outlet. When you unplug and replug the unit, it can temporarily fix the electrical problem, but it will likely reoccur if not properly addressed.
Defective Components: Certain components within the mini fridge, such as the thermostat, defrost timer, or compressor, could be malfunctioning. These components may temporarily fail, causing the unit to stop working. The cooling-off period during the unplugging phase might allow the faulty components to reset, enabling the unit to work again temporarily.
To diagnose and resolve the issue, it is recommended to consult a professional appliance technician. They can examine the mini fridge, identify the specific problem, and provide the necessary repairs or replacements.
