Samsung — Samsung Refrigerator, Model No.582, RT26FAJSASL/TL

I bought this fridge on 12.04.14. From 22 Feb.2015 the ELCB gets tripped. I disconnected all the other gadgets from the power lines and verified. The tripping seems to be caused by the fridge. When the ELCB is set right the fridge works for about one hour and then trips again. Now the tripping takes place every one hour. I am unable to keep any food in it. I have registered the complaint at Digital Venu's Arcade from where I bought the appliance. I would like to know the cause and the remedy for it. I have used it from the day I bought.
