Hello, I have a great Enviro Omega Maxx pellet stove however, recently a piece of plastic bag I assume from the pellets jammed the feed auger and wiped out the auger motor. I removed the auger and found the plastic wrapped around the top of the auger below the bushing. After inspecting both top & lower bushings I reinstalled and attached another motor. The stove worked fine for a day then the auger jammed again. It appears the auger gets so packed with pellets now it stops feeding. Can anyone help?
