SAFETY HAZARD FROM HAVING LIGHT BULB NOT WORKING WHILE MICROWAVE IS IN A COOKING CYCLE. FOOD BEING COOKED SHOULD BE VISIBLE UNTIL THE CYCLE IS COMPLETE. FOOD COULD BE DANGEROUSLY HOT AND OVERFLOW CAUSING A POTENTIAL SCALDING OF THE PERSON OPENING THE DARK COOKING CHAMBER. GE DOES NOT HAVE A REPLACEMENT BULB FOR THE XL 1800 AND MAKES A DANGEROUS SITUATION EVERY TIME IT IS USED. I HAVE CONTACTED SEVERAL CUSTOMER RELATIONS PERSONS AND EXPRESSED MY DEMAND THAT A NEW MICROWAVE BE SENT TO ME AT NO CHARGE. NO APPLIANCE SHOULD HAVE PARTS GO OUT OF PRODUCTION AFTER THE PRODUCTION DATE OF MAY 2006.
