My refrigerator suddenly turned off and we plugged difrent area but still the same.

See if you can find the defrost timer. Could be behind control panel or could be in toe kick. If you can find it turn the center screw about 1/4 turn, can only turn one way. If fridge starts to run, replace timer. Probably stuck in defrost mode. Will stick again in about 8 hours. Available at appliance parts stores.

Yeah, check the timer. If that ain't it pull the T-stat. if that ain't it check the PTC relay, if that isn't it check the overload. If that ain't it trace power from the chord until you find the break. If you can't do that, call somebody.
