KHMS105BAL4 KitchenAid Microwave - Instructions

All the electrics worked on Amana microwave EXCEPT for the cooking function. Inspected the control board and found the upper switch on the door interlock was burnt. Installed new switch in minutes and everything now works fine. Unfortunately, had to purchase expensive two switch "kit" although only one switch was kaput. PartsSelect mailing was SUPER fast. Thanks for looking, Scott

The problem I have with changing the bulb is my microwave is an overhead one and therefore I cannot tip it on its side to easily replace the bulb. I have to drop the lid down and carefully install the new bulb from underneath.

remove one screw from light and remove bulbs replace. I found the light plate had a lot of grease on rubber type washer for the glass cover. I cleaned it as best I could. The real trick was putting the screw back in when the Microwave is in with the hood Fan and the screw must go straight up and not miss the hole. I had someone hold the plate up and the screw went in. Your instruction book shows your filters and how to clean them. They are easy to and clean. What I found best is the lights they had been in for 15 years and the new ones are so much brighter. I now have an old set of filters that can be put in the dishwasher and used as a replacement when the new ones need to be cleaned.

remove 4 screws from top, front louvered panel snaps out. remove 1 screw from top of keypad, keypad pivot's forward and can be removed. There is a white mounting bracket inside left. Remove two screws, one top and one bottom, bracket lifts up and out. 3 sets wires are attached, mark them with masking tape, top, center, bottom and pull out plugs. They can only attach one way. Using a very small screw tip, lift plastic latch from switch, it rotates out and is removed from the pivot pin. reassemble in reverse order after switches are replaced

simply too the cover off the top vent area and removed the old one and replaced it with the new one

The door was not engaging the micro switches properly no doubt from 10+ years of wear. The upper switch removed fairly easily but take care not to tweak the plastic brace too much or it will snap. The lower one was the tricky one. After much examination I noticed that the trick to remove it was underneath the brace. Take a butter knife (no joke) and insert it just under the old micro switch and gently press down twisting the micro switch every so slightly til it releases. The replacements snap back in with no trouble. The microwave is working much better now, though not perfect.

I didn't do the repair -- my husband did, said it was easy, had no problems what so ever! The new bulbs give a lot more light to the cooking area.
