KitchenAid KEMS378GSS

Model # KEMS378GSS

Call (844) 405-1464 Schedule a Visit

The KEMS378GSS belongs to KitchenAid’s US microwave oven catalogue. KitchenAid’s own product material describes it as a Superba® 27″ Microwave Convection Upper/Convection Lower Oven, and that description is the whole of the published specification recovered for the KEMS378GSS. It appears on KitchenAid’s US product site in March 2000 and nowhere 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. Since the model is out of production, we settle what can still be supplied for it before the work is quoted.

FAQ

KitchenAid KEMS378GSS FAQ

KitchenAid gives the location for its microwave ovens as inside the door, and that is where the KEMS378GSS plate sits. It is an adhesive label, typically silver on major appliances, carrying the model number and the serial number together. Read the whole KEMS378GSS string off the label rather than from memory, because it sits in a family of very similar numbers.

Production of the KEMS378GSS 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 KEMS378GSS is settled before any figure is put on the work.

It usually means an interlock switch or a high-voltage component has failed. With the KEMS378GSS unplugged at the wall, the door latch and interlocks are what a technician checks first. Nothing behind the outer casing of a KEMS378GSS is owner-serviceable, because components in there hold a charge even after the oven is unplugged.
