Most common issues on this model

  1. A scorched waveguide cover, browned by baked-on splatter
  2. Bare steel showing where the cavity coating has rubbed away
  3. Printing worn from the keypad
  4. A door seal with nicks that upset the switches

Splatter is the enemy of the KHMS145J, sold as the KHMS145JBS and KHMS145JWH. Every cup of soup that boils over leaves a film on the cavity wall, and the film settles hardest on the waveguide cover, where the microwave energy enters.

That is why we examine the cover first. A brown or black patch means the cover is burning, and a burning cover can crack and spark. We replace it, clean the surrounding wall, and then look at the cavity paint where dishes have scraped.

The seal face of the door and the keypad come next, both tested the usual way. A written price comes before any part is ordered, and the repair includes our 30-day workmanship warranty. If the cavity is sound, we simply tell you so.

KHMS145JKHMS145J questions
There is a dark patch on the inside wall of my KHMS145J. What now?

Stop using the oven, because it is probably the waveguide cover scorching. We replace the cover, clean the wall around it, and then run a test cycle with a cup of water to confirm everything heats cleanly.

How can I stop splatter from damaging the oven?

Cover liquids loosely with a microwave-safe lid, and wipe the cavity after each spill once it is cool. Built-up splatter is what scorches the waveguide cover and eats the paint, so regular wiping extends the oven's life.

Are the BS and WH ovens different inside?

No. The KHMS145JBS and KHMS145JWH are versions of the KHMS145J base model, so the cover, switches and board match, and we use the rating plate to order any trim for your particular oven.
