It whines real loud as it drops pellets for about 3 or four drops then stops for a couple drops then the noise repeats. The pattern is the same every time. Seems like it only whines when it gets to a certain point in the rotation. The whine lasts for about two seconds as pellets drop.

Would this be the auger motor going bad? Stove works fine but the noise is annoyingly loud.

Buildup of Carbon? You think if it's motor it would do it all the time? Clean It
Could be but how does carbon buildup make the whining noise only when the auger spins to drop pellets? I am curious cuz I been running the stove since 2017 and anal about cleaning it. Am I missing something I should be cleaning?

I'm sure most pellet stoves make noise under the right conditions during the auger pulse ON, I have a 2004 enviro on a stone slab and it does the same thing, you can hear it resonating with zero ambient noise, I have greased the gear box(drilled a small hole and needle greased it), cleaned the electric motor and oiled its bearings, vacuumed and checked the auger shaft, hopper and bronze bushings, ready to add rubber insulators to the feet of the stove and then new auger gear box.., or maybe its just the nature of this stove design and I'm wasting my time.

There may be some carbon in the auger chute that binds the auger once or twice a revolution. That may be making the gears/motor whine.
