Hello I’m new to the forum and hopefully I’m in the right place for some help. I have a 1990 Whitfield Advantage II-T that was give to me. It has been in storage for a few years. The problem I’m having is when I first turn the stove on both the convection and exhaust blowers start at a high rpm. This lasts for a few seconds then then both go to a low rpm. I have no control over the speed of either of them after initial start up. No matter what the setting the stove only burns low. I have cleaned the stove completely and oiled the motors with no results. I’m completely new to pellet stoves (only wood until now) and any help would be greatly appreciated. Thanks in advance.
