The LED display goes blank or displays illegible graphics then will not work. We unplug the unit and plug it back in and it asks to reset the time, which we do and then it works for a short period of time. Seems as if the door closing at a certain point in the sequence is causing the problems.
Answer Hello Don,
The door switches, WB24X829 (two of these, top switch in assembly ad bottom switch in assembly) and WB24X830 (Middle switch in assembly) will most likely have to be replaced to correct the issue. If you want the door switches to last much longer, never use the door to stop the unit when cooking. Press the stop button then open the door. Turning the unit off by opening the door will burn the contacts in the micro-switches and cause them to stick or not close electrically.
