i am having an issue with my englander 25pdvc stove. here is what it is doing the upper auger only turns a fraction of a rotation every time it kicks on.i took a meter and put it on the board where the wires going out to the motor are and it went to 120volts for less than a second with the feed speed on two.so my questions are 1. if the vacuum switch is supposed to shut the power to the upper auger does that mean no power at all.2.is there any thing that is replacable on the board that tells the upper auger how long to stay on.
