Hey everyone! New to the forum. Hopefully I am posting in the right place for this question... I have a 1990 whitfield advantage IIt which on startup the combustion air blowing into where the pellets drop dies out after a couple seconds. I have to unplug and restart the stove 5,6 or more times for it to stay blowing to keep the pellets burning with a violent flame like it should be. I have just tottaly serviced the stove.. removed both blower motors, blew them out with compressed air and oiled them. Disassembled the vent piping and totally cleaned out. Cleaned out behind all the fire brick and behind all the other chambers that collect dust including the passageways to exhaust blower and intake. Not sure what else to do. I dont know much about the high and low limit switch sensors but im sure it has to do with the stove sensing the temperature and shutting itself off after it cools down. I have installed an upgraded control panel with the puch buttons a few years ago and has worked well for years after that. Also installed a couple years ago was a new blower on the side of the control panel that blows into the room. Any help would be greatly appreciated. Once I unplug and hit start button and do this several times it blows fine. Thanks!
