xteacher, the fuse is NOT the problem. When I plug in the microwave, the display screen reads 000, the microwave beeps once and when I open the door the interior light comes on. I CANNOT set the clock OR program the amount of time I want to heat up my food. If I push the buttons on the keypad enough times (10-20) the microwave MIGHT work or it MIGHT NOT. This is why I have said it is a manufacturing defect with the keypad as the original poster, a friend of mine and others are having the EXACT SAME problem. I cannot talk to the manufacture of High Pointe microwaves because they are made in CHINA!!!
