HOLDING both door firmly closed and HOLDING"on" button until it is lit
results in "on " button not remaining lit.
Yes, unit is plugged in. Yes, the obvious knobs have been altered to every conceivable position. Yes, the tab on the door is inserted in its slot properly. Even artificial depression of the mechanism which the door tab is to hold results in NO CHANGE in above problem. WHY will "on" button, which lights briefly when held NOT STAY ON?? How can this be fixed??
HOW IS THIS TO BE FIXED????
