Fridge And Freezer Forum

Hi, I hope somebody can help. I have a Brandt fridge/frezzer CFA361XU which is about 5 years old. For the last few months it's had a problem where every two days or so it stops working, the power and super freeze lights start flashing and the freezer heats up (it actually heats up the food in the freezer). If I turn it off at the wall and turn it on a 5 to 10 minutes later it will start to freeze again. I think the auto defrost switch is getting stuck on heat but I can't find it on the appliance?

Any ideas? Thanks.

I have had the same problem and the freezer back panel has melted
