New noise

[Boblinda41]

I have a Pro 22 and have used it weekly for the last 4 months. The last time I used it and again today about every 10 to15 seconds i hear a short (1 or 2 seconds) vibration sound. I assume it is when the auger turns on. Anyone have any ideas?

Other than a full deep clean, empty the auger to be sure that there aren't crumbled pellets in it, check the fan intake etc to look for any blockages or issues.
