My Kenmore 800 series dryer, model # 110.69822801, runs fine and heats fine. It will complete the entire cycle in Timed Dry mode on any heat setting except Normal / Medium High. When I use the Normal heat setting, no matter how much time I set it for, it stops at the 10-minute mark (10 minutes left to dry). If I turn the dial back up to higher than 10 minutes, it will start, but stops again at the 10-minute mark. When I turn it past 10 minutes, it won't start, until I move the dial to no more than 5 minutes; then it will start again, and finishes the cycle completely. Is this weird or what?
