Our microwave (Sharp R-1451) has been running fine for years. Yesterday it has begun to run (makes loud fanlike noise different than oven fan noise), when the door is closed. In addition, the keypad is nonresponsive for the most part. For instance, I have unplugged and can reset the time, but can't set a cook time or Sensor Reheat, etc.

THE FAN AND MICROWAVE TUBE RUN OFF THE ELECTRONIC TIMER. OPENING THE DOOR SHOULD SHUT IT ALL DOWN AND WHEN YOU CLOSE THE DOOR AGAIN YOU SHOULD NEED TO PRESS THE START BUTTON AGAIN. IF NOT, ITS SOUNDS LIKE AN ELECTRONIC RELAY IS LOCKED CLOSED ON THE TIMER BOARD.
