Down on the side of the compressor there is a black plastic connection box there should be 2 wires going in to it (one from mains plug (white maybe) the other comes / goes to the top control board, black maybe) unplug unit and remove cover there should be a black wire that plugs on a round thing behind the connection block get a bit of good wire and link from the brown Live to the black (this is basically the switch on wire) then power back up if the compressor fires up and stays on for 5 mins or more the fault is on the PCB control board, if it does not fire up check plug fuse if this is ok get a new fridge as the compressor aint worth touching!
