Why are there sparks inside my Roper microwave?

Sparks often come from a burned or greasy waveguide cover on the cavity wall, chipped interior paint, or metal left inside. Stop using it until the cause is found. Replacing the cover is an inexpensive repair if the magnetron has not been damaged.

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.

Roper Microwaves: What We Check First

Roper has never been a big name in microwaves, and you will not find many Roper-badged units in local kitchens. When one does turn up, it is a Whirlpool-sourced countertop or over-the-range model with the same basic layout as other budget microwaves: a magnetron, a high-voltage transformer, capacitor and diode, a set of door interlock switches, a turntable motor and, on over-the-range units, a vent fan and light. Many Roper kitchens actually have a microwave from a different brand, and we repair those too.

Door interlock switch failure blowing the internal line fuse
Magnetron, diode or capacitor failure leaving food cold
Burned waveguide cover causing sparks inside the cavity
Over-the-range vent fan motor grinding or stopping

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