Just tried to start my one year old Mt Vernon AE today and the auger doesn't feed pellets. I put a handful in the pot and they ignited but no more pellets were delivered by the auger. I cleaned the pellets out of the auger at end of last season so everything was empty. The hopper was about one half full. I left it try for about 5 to 8 minutes and didn't hear the auger run and no pellets were dropped. I have heard that at cold start up it can take longer. What should I do? Thanks for any help.
