My Whitfield stove is approximately 15 years old and recently when I turn it on it runs low. The auger light comes on but pellets are not going into the grate. It usually stays on for about 15 minutes then shuts off. I have had it cleaned recently and it worked well for about a week, then the same thing started to happen. I was wondering if you have any idea what the problem is and if you carry replacement parts. My local dealer in Nova Scotia says he cannot get parts for this stove. I would hate to buy a new stove when there is a chance that it can be repaired. I would appreciate your input on this matter. Thank you.
