hello, I am new to this forum and have tried to search for my symptoms and seems like a control board issue. I have a advantage ii-t I got from a friend that didn't work, cleaned it, checked wiring and seems good, not corroded or cut. Has a new blower fan and limit switches and auger motor also. I plugged it and and hit the power button and the fan is on high or close to high and the auger is on the lowest setting, and the control panel will not change the speeds for either component, nor can I shut the stove down unless I unplug it from the wall. Any help/verification greatly appreciated. Thanks -Jeff
