After about 7 months, the control panel failed. The light and the exhaust vent controls would not turn on and stay on or, once they were turned, they would turn off by themselves. The appliance dealer we bought the vent from replaced both the control panel and the exhaust motor because they really didn't know what was wrong with it. And forget about cleaning the stainless steel chimney vent. It streaks with sudsy, warm water or darkens and streaks with stainless steel appliance cleaner.
