Richard H Collegeville , PA March 28, 2016 Appliance: KitchenAid Microwave Hood Combo KHHS179LSS2 Kitchenaid Microwave Khhs179lss2: Microwave stopped working and door would not latch (likely why the microwave was not working). How to replace Switch. Took the control panel off. Took the door latch mechanism parts out. Paying attention of where the wires were connected (I drew a schematic) so I could put the microwave wires back together again. Then I put the new switch in place. I used a set of "star" wrenches to remove the door-latch hardware on the microwave. This is a unusual set of wrenches I happened to have on hand. 18 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
