I need the experts for some help here. I have a Whitfield Adv II-T. I have had it for 10 years, never a problem. Today, after running for over an hour, the stove shut completely off for 10 seconds (Like the power went off), then restarts like I hit the "START" button. If I had the auger/blower control on level 2 (2 green and 2 red lights) the stove always comes back on level 3. Sometimes it takes an hour, sometimes it takes 15 minutes to do this. Any thought or suggestions would greatly be appreciated.
