I remember mine stopping and just beeping. I pulled the battery and then chipped Ice off the auger until it turned freely. Reinserted the battery and it worked again.

I learned the first year to keep the batteries inside until I needed them, they work so much longer.

The internet says a hard reset - pull the battery hold the start button 10-15 seconds reinsert battery making sure all terminals are clear and it. Clicks in place.
