I have found a solution for my stove whistling while feeding pellets. My stove is about 10 yrs old and started whistling towards the end of last season. What I did was empty the hopper and ran it while I listened. It was definitely coming from the auger. I moved the stove in order to get access to the back panels. removing the panels I noticed there is a two hole flange that holds the auger in place. I removed the drive chain so I could spin the auger and listened for the noise. Then I slightly loosened the hold down bolts while spinning the auger until the noise stopped. Seems that you need to have proper tension on those bolts so the auger doesn't cock slightly. Feel free to contact me with any questions.
