Product review (5 stars): Good service, solved out problem
When our Kenmore Elite Oasis HE Top-Loading washer started stopping and showed F-1 errors, we found out it means the main control board is going bad.  We ordered this from Virginia Service Supply through Amazon, and the part arrived quickly and was very easy to install.  The F-1 errors went away, and our washer worked fine.
  Until 3 months later...it started stopping at the final spin with the uL code, which is unbalanced load.  It was intermittent at first, and became 100% after a few days.  We checked all of the physical parts...the drum suspension, the levelness of the machine, and everything looked good. No items below or around the drum.  When the uL indicator comes up, the machine is very quiet and not shaking at all.  We found it could be the rotation sensor or the main controller board.
  We contacted the seller and they asked a couple questions, and agreed to send a replacement.  Even if this doesn't solve the problem, the seller was very helpful to agree to send a new control board.
Now we just have to see if it fixes the problem or if we need to make more expensive repairs.
