Bought a Masterbuilt Electric some time ago and have had great success with ribs, brisket, etc. Last week I was asked to cook a large amount, [8 racks] of ribs for a senior dinner. Had to cut some up as I only have 14 inches of width. Bought two rib racks and got all 8 racks of ribs in. First time ever the smoker wouldn't get up to any higher than 205 degrees? Went ahead and cooked them at that temp and came out ok. So what happened? Haven't called they hotline yet.
