Purchased a couple year old unused Mr. Vernon AE pellet insert in January 2011. On several occasions now, the feeder has dumped more pellets than it can burn and even over filled the burn pot to the point pellets were backing up the chute. I originally thought it had buildup in the firepot, but after poking in it and nothing falling I realized it was full to the top with unburned pellets. The fire was still going but weak and with lots of smoke. The fire had even began to burn up the chute. This causes me great concern as I don't want it to burn all the way up into the hopper. Has anyone had this issue and found a resolution for it as well? Unfortunately I have no warranty having not been the original purchaser.
