I have a friend that has been given a small pellet stove which appears to be several years old, but in fairly good condition other than the control board. The knobs are broken off that control the high and low feed rate, it has a 4 position selctor switch for the room air blower which is very stiff and extremely hard to change positions. I have went and looked at the info plate on the back of the unit and it does not have a name of the manufacturer or a date in which it was manufactured. It does have a Model # 5440 and a serial number# 001623 . The unit is working ok but needs some adjustment to the feed rate as it over runs the burn pot. We have helped some by pulling the damper rod on the side of the unit out to allow more air but we still need to reduce the feed rate if possible. We would really like to get a new control board if possible and this little baby will be as good as new. I would appreciate any help that anyone may have.
