The first thing to check when a refrigerator stops working is the power supply. Make sure that the fridge is plugged in to an outlet and that the outlet is functioning. If it's plugged in and the outlet is working, then check the fuse box or circuit breaker to make sure that there hasn't been a power outage. If everything looks good on that front, then it's time to call a technician.

You should check the power supply to the refrigerator. If it's plugged into an outlet and there's power running to it, then you should check the fuse box or circuit breaker to make sure that there isn't a tripped breaker or blown fuse. If everything looks good on those fronts, then you'll need to call a technician to investigate what might be wrong with the refrigerator.
