I have had the stove a little over 3 years and had to replace the igniter 3 times and now a month after they replaced the 3 rd igniter it is making strange sounds and randomly shuts off in the middle of cooking.   They came out to look at it and said it is the internal cooling fan. And they  now have to pull the whole stove out to get to the back. I just did a custom renovation and that will now ruin my custom tile work and crack the granite !  And probably will never go back in correctly ! I am so disgusted! I went with GE instead of Viking and regret it every day !
