Went to check on stove this am and found the burn pot full of pellets burning, but the mechanism that turns in the burn pot was not turning and the pellets had built up to the shoot so no more could come down and they were starting to catch on fire in the shoot. We turned off and cleaned the burn pot thoroughly. We opened up and found the small metal shaft with the chain on it in the back had snapped near the motor. We clean the stove frequently even though we don't really need to, but we are being overly cautious so things like this wouldn't happen. any ideas or help would be appreciated. It seems to us that this is a defect. We bought the stove in August and have only been using it since November. thanks for any help!
