Having an issue with the Dial-A-Fire. The interval between pellet drops at the coolest setting should be 15 sec and at the hottest setting should be 5 sec. My stove had a 5 sec interval at the coolest setting and a 1 sec interval at the hottest setting, so I purchased a new timer module and potentiometer. I installed them both and I still have the same issue. The stove was purchased brand new in July of 2008. Any help would be greatly appreciate. Thank you.
