I bought a Lopi Pioneer Bay pellet insert in 2001. The thing worked OK for the first 4 winters (evening use only, faithful maintenance as per owner's manual). It needed a new blower in 2005. Now it is nearly impossible to light and if it does light, it goes out. There are few pellets in the firebox even with the auger set to HIGH and there are massive clinkers during the short time fire actually happens. A service tech came out 2 weeks ago and adjusted the air - he said it was getting too much O2 and that was burning the pellets faster than they could fall. HUH? 2 weeks later it is malfunctioning as before. The gasket doesn't leak. It is not too much 02. Sometimes the auger light comes on and no pellets drop. There seems to be no correlation between auger setting and amount of pellets. Each night of the 2 weeks since it was "fixed" it has burned fewer and fewer hours before snuffing itself out. It will be several weeks before a tech can return (yes, the same one who "fixed" it before - these techs are rarer than hen's teeth in California and will only work on stoves sold by their store.) My question - does this sound even remotely fixable? Do any of you have any ideas as to likely causes? Is there anything at all I can do myself? And perhaps the most important question, should I dump this crummy Lopi machine and buy a new stove? I'm afraid I am throwing good money after bad right now. Thank you!
