Microwave repair in Gaithersburg
In a narrow rowhouse kitchen the over-the-range microwave earns its space by also serving as the range hood, often exhausting back into the room through a charcoal filter because there is no easy path outside. Larger houses in the ZIP tend to build the microwave into a wall-oven column or an island drawer, with trim kits that tie it into the cabinetry around it.
Our checks on a microwave that has stopped heating
Safety comes first: the unit is unplugged and its high-voltage capacitor discharged before any panel comes off. Then we test the door switches and the monitor switch, because a misaligned door can blow the main fuse every time it is opened. If those check out, the high-voltage circuit is tested part by part, from the transformer and diode to the capacitor and the magnetron's filament. Arcing inside the cavity leads to the waveguide cover and any chipped interior paint. Dead keypads, stuck turntables and failed vent fans each have their own short list of parts to test.
Recirculating vents and trim kits in 20878 kitchens
A recirculating microwave in a Kentlands galley depends on a charcoal filter that should be replaced periodically, along with the metal grease filters underneath. Built-in microwaves with trim kits need the trim removed carefully to reach the mounting screws, which we do without marring the cabinets on either side of the opening.

Have a different question?
Tell us what make it is and what's going wrong. A few things can be settled over the phone, and anything else gets looked at during the visit.
Many models start the fan automatically when a sensor detects heat rising from the burners below, to protect the electronics. If it runs while the cooktop is off and cool, the thermal sensor or the control board may be faulty, and we test both, along with the fan relay that switches it.
