I have a "Lexington Forge" LX36DVN made by Monessen. I am facing the reality that the blower motor is out in the thing. I was SO hoping it was the thermostat sensor. Well no luck. Does anybody out there have a clue how to get to that thing to get it out? Do I go through the floor of the firebox or do I literally have to remove the whole fireplace from the frame itself? Any help would be greatly appreciated.
