I am trying to find out some info on a feeding problem my mother in law has with her Whitfield Advantage II-t stove. The stove is about 13 years old and has essentially been problem free with the exception of a control board replacement 2 years ago.Tis winter she has started to experience a problem with it in respect to the fact that it is all of sudden starting to dump a lot of pellets out all at once and is extingishing her fire. She is also saying that the settings for the auger speed are generally set at 2 and she has noticed that when this is happening it has also reset itself to a feed rate of 3. Not being familiar with this pellet stove model I don't want to assume that it is a failed control board off the bat. Any suggestions?
