started having problems this year with my stove. every week or so on start up the stove will fill pot about half full of pellets and not ignite. press rest button and works fine for about a week then same problem,now it is getting more frequent , about every day. I have cleaned the stove,changed board,thermocoupler,igniter,door gasket,and snap disc #2. local dealer is stumped,anyone else have this problem. Also the instuctions that came with new board saves on shutdown the combustion motor should run for 18 minutes,mine only runs for 10. In the owners manual that originally came with the stove it says when there is a overheat that the stove goes into shutdown and the combustion motor runs for 10 minutes.i know the stove is not overheating because if I turn the thermostat really high it wil run for as long as I need. anybody have any advice.
