I have a 30" Wolf Dual Fuel Range - it is almost 5 years old. For the last 2 years I have been trying to get someone to repair it. The computerized control panel for the oven doesn't work properly. I have an extended warranty on it - every repair company they send out look at & say it needs parts & they'll be back. The never return nor do they ever call. Called Wolf & place where purchased. They sent out an "authorized Wolf repairman". He promised to call back and has never called. Anyone else have these kind of problems with a Wolf Range?
