P61a pellet feed problem

[greywolf46]

MY P61a shut down after pellets stopped feeding the burn pot. setting on stove temp auto - setting #4. When it is running, the feed motor comes on and auger turns but pellets are not coming into burn pot, so it shuts down. I cleaned the fines box and replaced the ESP recently. Stove ran ok for a few days then it started doing this. Any help appreciated.

Many a part of a melted plastic bag or child's toy has blocked augers over the years. Scoop out the hopper and check.

While it is empty, run stove and see if slide plate is working.

Or pellets 'bridging' at the bottom of the hopper. Happened once on my XXV.
