If you continue to have issues you might remove the plastic control unit cover on top and look if moisture is in there. My cooker eventually stopped working. When I removed the cover I found that steam and smoke had been leaking up thru the metal cabinet into the area where the electronic control board was located. The board was corroded and I had to replace it. I removed the entire metal case and sealed certain areas where the steam could get thru. The biggest area of leakage is in the front on top of the door. The steam comes out of the door and leaks up into the top of the cabin. I have a thread on here somewhere I think.
