Ok my Profile 30 has been working great for years. One day when I fired it up it started fine great flame and heat then in about thirty min you start hearing a funny buzz noise everytime the augur turns and the flame is like it on low. Its like the pellets are not dropping down fast enough. I work on all my own stuff and pretty handy when it comes to working on things. So I took everything apart and cleaned everything on how the Forum suggest to clean and been doing my normal cleaning. Noithing was to dirty cause I just did a full cleaning in Oct before I started using it. The eye is clean and the auger does turn and the stove never turns off by fault. Not sure what to do next the augur set screw is tight. Any help would be helpful its could out. Thanks
