Why does my KitchenAid microwave vent fan run by itself?

Over-the-range microwaves have a thermostat that turns the fan on automatically when the cooktop below gets hot. If the fan runs without heat, the thermostat or control may have failed. A technician can test both.

Our microwave drawer in a Marvin kitchen island will not open. Can you fix it?

Yes. Drawer microwaves have a motor, gears and a latch that can wear or jam, and the control board or touch panel can also fail. We test the mechanism and electronics in place and tell you what the repair involves before starting.

Can you repair a microwave-oven combination unit in Waxhaw without replacing both?

Usually. The microwave and oven sections share a cabinet but have many separate parts, so one side can typically be repaired alone. If a shared control has failed, we explain that and the price.

KitchenAid Microwaves: What We Check First

KitchenAid microwaves come as over-the-range units with an exhaust fan and lights, built-in models that pair with wall ovens, and some with convection capability. The core of each is the same: a magnetron powered by a high-voltage transformer, capacitor and diode, a set of door interlock switches, a turntable motor and an electronic control. Over-the-range models add a vent fan and light that run off the same control.

Magnetron, diode or capacitor failure leaving food unheated
Door interlock switch wear preventing the microwave from starting
Keypad or touch panel unresponsive from steam or grease
Vent fan motor or thermostat failure on over-the-range models

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our KitchenAid microwave repair guide.

Microwave Drawers, Trim Kits and Combo Stacks

Larger kitchens often move the microwave out of sight. Microwave drawers in islands use a motorized opening mechanism, so in addition to heating faults they can fail with a drawer that will not open, closes partway or stops responding to the touch panel. Built-in units with trim kits and microwave-oven combinations are tied into the cabinetry, which changes how they are removed and serviced.

A dead microwave after a summer storm sometimes just needs its power reset. Check the breaker, and if the unit has its own outlet in a cabinet, make sure it is still live. Do not open the housing: the high-voltage capacitor inside can hold a dangerous charge long after the plug is pulled.

Our technician tests door or drawer switches, the drawer motor and gears, the magnetron, diode, fuse and control. Some built-in parts are ordered, and we will let you know. If a repair costs too close to a new unit, we say so before you spend anything.
