KitchenAid KBMC140HBT

Model # KBMC140HBT

The KBMC140HBT is one of the KitchenAid microwave ovens. No published specification for this model was recovered. What survives is the model number and a dated record of when KitchenAid was showing it, and that is what is set out here. It was on KitchenAid’s US product site from December 2003 to August 2004 and gone after that.

A microwave oven of that vintage is two decades or more into service, and the door latch, the interlock switches and the turntable drive are long past as-new. Discontinued does not mean unrepairable, but it does mean availability of the specific part for a KBMC140HBT is established before any figure is put on the job.

FAQ

KitchenAid KBMC140HBT FAQ

KitchenAid gives the location for its microwave ovens as inside the door, and that is where the KBMC140HBT plate sits. It is an adhesive label, typically silver on major appliances, carrying the model number and the serial number together. Read the whole KBMC140HBT string off the label rather than from memory, because it sits in a family of very similar numbers.

Production of the KBMC140HBT ended some time ago. That does not rule out a repair - the wear items are largely shared across a generation - but it does mean the parts question on a KBMC140HBT is settled before any figure is put on the work.

On some builds the cavity lamp is reachable from inside, but on many it sits behind the casing. With the KBMC140HBT unplugged at the wall, only a lamp accessible from within the cavity should be attempted. Where the lamp in a KBMC140HBT is behind the casing, it is left to a technician for the same high-voltage reason as everything else in there.
