I've been using a Lopi Revere just about 24/7 for seven seasons now. The fan is a must have. Those switches get "lazy" after a few years and need to be replaced. My fan will cycle on and off repeatedly as the stove warms and that's how I know it's time to buy another $15 switch from the neighborhood Lopi dealer. I also give the fan and it's housing a good cleaning twice each season. It is unbelievable how ash and dust will reduce the efficiency of the fan.
