fridge causing all sockets in kitchen to trip out????

hi there i have my zanusi fridge about 5-6 years and tonight it stopped working and it tripped out all the sockets, i remove dfridge from built in unit to access the plug thinking that the fuse had blown put in new 13 amp fuse and plugged it in again and it still trips out the sockets i plugged out everything in the house also just to eliminate the possibility of being something else, any body have this trouble before or have any suggestions thanks
