'Til this fall, we've not had any trouble w/our Baby Countryside, but now it won't emit any heat. Auger and blower work fine, but the air coming out is barely warm. We've thoroughly cleaned it twice. Replaced the door gasket/rope. Hired a "pro" who cleaned it, adjusted the draft and serviced it. Tried 4 different brands of pellets. I'd sure appreciate your ideas on what we should try next.
