I own a profile 20 and a st croix JOHN DEERE EDITION and my profile 20 for the last few weeks gives me problems....feels like fan for combustion is lacking voltage or turns slower tha usual,pellets are gathering in grate and grate is overflowing after fews hours of heat.Unplugged motor from stove and jumped wire to ac outlet and problem seem to be resolved.Is power controlled by the electronic control...would control not sending enough power to fan.................just joined that forum and it is a great help...thks a merry xmas
