The fan works great, as long as the stove is off.  As soon as the stove gets a little warn the fan and lights shut off and will not turn on again till it cools down.  Now I'm not talking about a lot of heat here.  Just trying to boil water, and before the water even starts to boil the thing turns off.  Have not been able to get in touch with tech support so dont know yet if there is a fix .
