I have a Better N Bens wood stove. It is the larger model of the two fireplace insert stoves that were available back in 1977. With this stove I have a side blower housing that inserts its nozzle into the stove's side to supply air flow around stove and out the stove's top into the room. The blower within this housing is no good & I need a repair/replacement. Any & all suggestions will be greatly appreciated.
