KitchenAid KCMS145K Microwave Service

The KCMS145K is an older microwave listed with a single other version, the KCMS145KBU. Cavities on units this age often show a bare patch near the floor or back wall where glass dishes have scraped, and that is the first thing we look at.
A bare spot is not just ugly. Metal exposed to steam and splatter rusts, and rust can spark when the oven runs. We examine the cavity under strong light and give you a straight answer about whether the spot can be treated or the oven should be replaced.
The door seal, keypad and heating strength get the usual tests after that. You receive a written price first. Any repair we make comes with a 30-day workmanship warranty, and we will tell you plainly when a repair is not worth the money.
Small spots can be cleaned to bare metal and sealed with oven-safe paint. Large or deep rust is a different matter, and we will advise replacement rather than patching.
Yes, the KCMS145KBU is simply another finish listed under the KCMS145K base model. The working parts are shared, and we choose any trim from the rating plate when we are at the oven.
Treat it as serious. Sparks usually come from bare metal, a damaged waveguide cover, or metal such as foil left inside. Unplug the oven and stop using it until we have inspected the cavity and found the source.
Book in about a minute, or call the desk. Same-day windows inside the Loop on most days, next-day across the rest of Houston.
