Help! I have a new this season Lennox/country Winslow insert model p140 http://www.lennoxhearthproducts.com/products/overview.asp?pid=464 I burned through my 1st ton no problems. It started making less heat, so i figured it was time to clean the thing fully. since i've cleaned the stove, i have not been able to re-start it for more than 20 min. It fires right up, burns great, then the auger just stops feeding pellets. It eventually just burns out. Sometimes, it will throw an error code (out of pellets, snap switch detetcs no flame), but most the time it stays green. My dealer is worthless and i can't seem to get ahold of anyone at lennox who wants to help me. I've triple (hell, 20-times over now) re-checked everything, all the seals, its freshly clean inside and out.... and it was working mint before i did all this cleaning. I feel like it was me, but it could just be coincidence. I figured if i did something wrong, it wouldn't start up at all. But it does, and then just dies out. Anyone have any pointers?
