Why does the motor my Sears vacuum cleaner model 11631912100 run backwards and blow air into the back compartment?

I have a vacuum cleaner model 11631912100. The motor runs backwards blowing air into the dust-collection-bag-compartment instead of sucking it out. What repair or part needed?

My question is still unanswered. Yes the air is blowing back out of the suction hose - the motor is running backwards. I was told by the parts department that Sears was using this site to support repair questions. The vacuum cleaner is not worth a $100 service call. I was wondering if the PcB (printed circuit board ~$25) controls the direction of the rotation of the motor or if there was a capacitor on the motor that might need to be replaced.

I am having a hard time understanding your problem with the vacuum cleaner. If the vacuum motor was running backwards, it would be blowing air out of the suction hose. The vacuum cleaner will normally have air flow into the dust bag. If the dust bad is broken or has a hole in it, it could be allowing too much air flow into the bag compartment. I recommend that you check the bag.

If the vacuum cleaner is blowing out the suction hose instead of sucking in, I recommend that you have a service technician diagnose and repair the vacuum cleaner. Accessing the components and maintaining the proper wire routing in this vacuum cleaner is best accomplished by an experienced technician.
