The Viking stove I bought five years ago is far and away the worst piece of kitchen equipment I ever used. I have run a bakery and catering business and written two cookbooks so I've used a lot of stoves over 40 years. This is absolutely junk put out by a company with absolutely no integrity or decency and thus of course no customer service. Instead of admitting they sold a faulty product like my stove who h from the getgo burned anything at any heat and causing me to pay for two new thermostats neither of which changed anything, what those sneaks did was issue a whole new part.
DOnt buy anything Viking even if that's all there is. A crappy fridgaire stove I had in a rental recently was more reliable.
