Sounds like a bearing is starting to go.
The direct drive motors have sealed bearings. Bearings are good for about 3 years depending on how much heat get to them.
The motor can have the bearings replaced and a good motor shop can do it but there will be some down time.
I had the draft motor on my Dad's woodgun rebuilt two years ago and it cost $15 for the bearings and $60 for the labor for a total of $75.00.
If the unit is under warrenty, get directions from AHS on how to claim the warrenty.
