Panasonic Microwave Nn-s553bf age 9/2003.
Worked fine until.... microswitch bracket broke, I then three 24v switches, 2-N.O and 1-N.C to activate simultaneously as the door closes. So now the control pad works fine AND I did a master reset (press reset three times) THEN I press a Quick Minute,,,,it tries to start BUT it shuts down and digital readout goes blank... Then I press rest once... then again press quick minute,,, same things happen. If I unplug power just to the rectifier board,,,then it will only time down the quick minute and the light and fan will too
WHAT IS THE PROBLEM? (Maybe the microswitches have to activate 0.5ms sequentially?)
