Just received our 30” Thor electric stove! Looks beautiful! We turned on the oven for the first time and noticed a lot of smoke with a distinctive smell coming out from the rear air grill/louver. We don’t know if it’s burning off dust or if it’s just because it’s new and has never been used? If guess we’ll give it another try and see if it improves with time. We had our electrician check out all electrical connections and it’s all good to go. ??
