This is my second microwave from LG ... seems like I had to be jolted twice to force me to change .... body of the first microwave just melted from one place and I could see a gaping hole after about 2 years of usage .... So what do I do ... I buy another LG Microwave .... and in this case ... just after 1 month of warranty expired ... smoke started coming out of the MW ... checked with service engineer... he said the company to reduce the price has lowered the quality considerably ... So in this case the Transformer has gone .... repair Bill: 2000 INR
