Question about KitchenAid KHMS155LSS 1000 Watts Microwave Oven
Your owner's manual should have the part numbers and instructions for replacing them.
You can download owner's manuals and installation instructions for several brands (including Amana, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.
If the manual does not cover it, then it's not designed for the owner to do, you would need to remove the oven from the wall and remove the outer cover.
You can find links to helpful exploded view diagrams and part ordering help here. I'd recommend that your bookmark this link to your favorites.
Once you get new bulbs in, if they still won't come on, or if they're stuck on, or you have trouble with either fan, the surge of the failing bulb may have damaged the board.
We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week or two.
This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
This can often also affect the exhaust fan, cooling fan, turntable, and/or inside light operation, too.
Details of our service are at our Web site, along with a video showing how to remove a typical over the range control panel assembly in under 5 minutes.
Feel free to contact me directly with your brand, full model number and symptoms.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
