I Have a Used Avalon Newport Bay Pellet Insert that came with the house I bought. The room blower fan doesn't stay on all the time and unit gets extremely hot. It will start with a manual push but will go off soon after. It stayed on all night last night after acting like this yesterday, but has gone back to this mode. Could it the fan motor failing or could it be a control device acting up. It has previously melted the vacuum line at the exhaust blower fan which was a clear line that may have been wrongly replaced previously by the last owner. I have used high temp silicon. Any help would be greatly appreciated.
