Hello. First sorry my english is not perfect. My LG Range make constant loud cliking noise when oven's working when preheat and heat. He click every 30 seconds 3 times fast. It's really disturbing et the clicking sound is realy loud. I even hear the click at the other end of my house. I call LG 2 times. The first guy told me that it's not normal and the other one said its normal. If your do the same thing, please send me a message i will appreciate it.
