KCMC155J* panel replace the fuse

Unplug microwave or shut off house breaker. Remove grill or cover that goes across the top of door and control panel.Remove screw that holds control panel on and lift up on control panel. It will tilt downward and has 2 tabs at the bottom that go into slots. It can be lifted out of those slots.The fuse should be seen at the top area in the microwave behind where the control panel was mounted. Fuse is usually small 1/4 round type fuse like old type car fuses that were glass but the micro fuse will be either a white of gray ceramic fuse not glass. Some are 15 amp some are 20 amp. Usually stamped on end of fuse.

Most microwaves have a shield over the light bulb in the cooking compartment. Some are accessed from the outside most from the inside. Check to see if there are clips or screws that need to be removed to pull the shield off. Careful if there are screws, they are usually coated to prevent the waves from arcing if you crack or break off the coating you could have problems with the microwave arcing

The service number for this microwave is 1-800-422-1230. I have seen this question posted on several sites with no answers. Also, I checked the Owner's Manual and I do not see an answer to this question. If I had to guess, I would say that if there is no access from the inside of the microwave, you may have to remove it from the wall as the access might be on the back of the unit.

Check the door interlock switches and condensation on the control panel.
