Why is my mini fridge suddenly silent and not making any noise?

Your mini fridge may be suddenly silent and not making any noise due to a malfunction in its cooling system or a problem with the compressor. It could also be caused by a power issue or a faulty thermostat. It is recommended to unplug the fridge, wait a few minutes, and then plug it back in to see if it starts working again. If the issue persists, it may require professional repair or replacement.
