It was warm today, mid 50's so the stove hardly ran... Came home from work and saw the indicator that the hopper was almost empty. I checked and it was 3/4 full or better. I moved the pellets around, still showing the low pellet level indicator. I pulled the side panels and checked things out. I gave the underside if the hopper and drop tube area a few smacks lightly with just my hand. After that the indicator went away. Not sure if I should just let it go or check things out further. Any ideas?
