Problematic Samsung Combi Microwave.

I bought a Samsung CPI395EST COMBI Microwave . It has a sensor weight system that I DO NOT USE on this oven. This weight system broke a year ago and was replaced as the whole oven system does not work without it. It has now broken again and I have had to replace it from ALL ELECTRONICS with a 1 month guarantee. This has cost over R1000.00 . I have never had problems like this with my other microwaves.
