Hi all, I really need some help. I bought a used jamestown j1000 off of a friend and can't get it to work properly. I believe the stove is an early 90s model because nothing is digital on it. I can get the stove to work for an entire day sometimes but most times it either will burn out due to too many pellets dropping no matter what temp it's at or it won't drop any pellets at all. I've replaced the control board and auger motor. What else can I do? Thanks in advance
