KitchenAid KBMS145 Built-in Microwave
Built-in microwave with a drop-down door; owners most often report turntable faults, sparking or heat that stops mid-cycle.
Model overview
The KitchenAid KBMS145 is a built-in microwave with a drop-down door and a 1.4 cubic-foot cavity rated at 1,000 W. It offers ten power levels, sensor programs for popcorn, baked potato and meal reheat, and a control panel with touch pads and a dial. From Houston to San Diego, the reports on this microwave center on turntable trouble, sparking inside the cavity and heat that stops while the turntable runs. The booking form should record the symptom, the complete model number as printed and whether the sparking shows up with one food.

What sets the KBMS145 apart
The drop-down door is the feature that most separates this unit from an over-the-range model, since it sits in a cabinet opening rather than above a cooktop. The touch pads and dial share the panel, and the removable turntable can be washed by hand. Supply is 120 V, 60 Hz on a fused 15- or 20-amp circuit.
Service notes for the KBMS145
Sparking inside the cavity usually points to metal, food residue or a damaged waveguide cover, so a technician checks the interior before suspecting the magnetron. Heat that stops while the turntable runs narrows the fault to the power path rather than the turntable motor. A turntable or light that stops working is a motor or bulb question. Fan noise belongs to over-the-range models, so describe a fan sound only if a separate hood is installed. Owners can clear residue from the cavity, check that the turntable seats on its support and note whether sparks show up with metal in the cavity.
The model number is printed on the rating label, usually on the frame around the door opening, visible with the door open; match it letter for letter before booking, because a single letter can change parts.
