HI WELCOME TO JUST ANSWER.I WILL BE ASSISTING YOU WITH YOUR QUESTION TODAY. YES IT MAY BE ON THE SIDE OF THE CONTROL INSIDE THE DOOR. ITS OVER TO THE RIGHT OF THE MODEL.
The sears tech that came to the house to repair it siad the label is missing, possibly do to it being cleaned and removed. Is there another place the serial number and model number can be found. The will not repair it without this information.
NO, AND NO ONE WILL WORK ON IT BECAUSE ALL MODEL NUMBERS ARE DIFFERENT. MOST MAJOR REPAIRS ON A MICROWAVE COULD COST AS MUCH A NEW ONE. IT WOULD BE YOUR BEST INTEREST TO PURCHASE ANOTHER MICROWAVE.
