Most common issues on this model

  1. Bare metal patches in the cavity where plates scrape, followed by rust
  2. Faded key printing that hides which pad is which
  3. A damaged seal edge that confuses the door switches
  4. Slow, patchy warming as the magnetron loses strength

The KBMC140H was sold as the KBMC140HBT, KBMC140HSS and KBMC140HWH, three versions of one base model. The most visible damage on an oven this age is inside, where dishes have rubbed the cavity paint thin.

Bare metal at the rubbed spot invites rust, and rust is the one thing that can spread into a bigger problem, because it can arc in service. We check the cavity under a bright light, and tell you honestly whether a spot touch-up is enough or the oven should be retired.

Beyond the cavity, we test the door seal, the keypad and the heating strength with a water load. A written price comes first, and our 30-day workmanship warranty covers any repair we make. If the oven passes every test, we say so and leave it as it is.

KBMC140HKBMC140H questions
There is a rusty patch inside my KBMC140H. Is it dangerous?

A small spot can often be sanded and sealed with the right paint, but bare metal can arc. If the damage is large or near the waveguide, we will tell you the oven is better replaced.

Which version do I have?

The BT, SS and WH endings mark the three versions, but all share the KBMC140H base model. We match parts using the rating plate inside the door or on the back.

Why is the door seal important to heating?

The seal keeps the door closed against the interlocks. If its face is chipped, the oven may think the door is open and refuse to start.
