Combustion blower seized up on my Accentra insert . After searching around for a new one I decided to pull it out and take a look. It is serviceable. so don't consider it dead. There are two bearings 608s that were very dry. After some pb blaster and some oil, the bearings are spinning free. Its hard to find such a bearing on the weekend so back into the stove they went. Fired right up. Until I get the new bearings the old ones are doing fine for now.Im back in business. Hope this helps someone that may run into the same problem. ps Using that oil burner last night made me realize how much I enjoy my stove.
