Stove is a newer install, been having trouble with lazy flame. (see my previous posts) Yesterday when I started the stove the combustion blower made a screeching noise. I shut it off, restarted and noise was gone, but still lazy sooty flame. I've cleaned the stove thoroughly many times. When i went to restart today after cleaning the stove and filling the hopper, the exhaust/combustion blower didn't even come on. Have tried several restarts since, but it won't start. I can hear a slight hum, that is about it. Just bought the stove a month and a half ago, and it is our only source of heat. Loose connection perhaps on the control board? Wire issues somewhere? Faulty combustion blower? Suggestions?
