Samsung RL36SBMS Bottom Freezer. The problem is that the fridge and freezer have stopped cooling altogether. The electricity is getting to the appliance, the light is on and a low humming noise (fan maybe motor?) can be heard. But there is no drop in temperature however long the appliance is left on.

Can u help pls:
1. What is the likely cause or troubleshooting?
2. I have removed the back inspection panel and there seem to be almost no parts to replace - certainly no fuses I can see?

Look forward to your advice. Cheers and thanks in anticipation.
