Kenmore Microwave Repair in Bethesda & Chevy Chase, MD

Kenmore microwaves have been made by outside suppliers, LG among them, so the tag is the first thing we read. Over-the-range models are two appliances in one: a microwave with a magnetron and high-voltage circuit, and a range hood with a vent fan, lights and grease filters. The common complaints are a unit that spins and hums while food stays cold, which traces to a door switch, diode, capacitor or magnetron, a turntable that stopped turning, and a vent fan that is loud or dead. The high-voltage capacitor holds a charge after unplugging, so it is discharged before any testing. Over-the-range units are heavy and awkward to lift down, and that labor is part of the repair-or-replace math we go through with you.

Where we start on this pairing: Door interlock switch failing; Magnetron no longer heating; High-voltage diode shorted; Turntable motor stopped; Hood vent fan noisy or dead.

Treat that list as leads rather than conclusions. Identical symptoms can hide a minor fault or a major one, and the only way to know which is to test the appliance where it's installed, which comes before any quote.

In the downtown condos the microwave is usually an over-the-range unit doubling as the hood, or a trim-kit model set into a cabinet beside the wall oven. Newer kitchens in Chevy Chase and Bethesda often put a microwave drawer in the island instead, where a crumb in the track or a bumped front can stop it opening. Any built-in version has trim or a mounting plate that must be handled with care, because matching cabinetry can't be swapped in an afternoon.

Gas from Washington Gas is common in the older houses, the condos lean toward electric and induction, and many rebuilt homes carry a pro-style range or a stack of wall ovens.

Whatever the brand, the microwave symptom that misleads people most is a microwave with a working light, fan and turntable but no heat, which usually means a magnetron, diode or capacitor rather than the control board.

Locally, what we watch for most on a microwave is over-the-range units that double as the only kitchen hood, and drawer models built into islands.

Garage refrigerators around Bethesda & Chevy Chase have their hardest months in July and August, when a shut garage can get far hotter than the kitchen. The compressor runs nearly nonstop, the condenser fan labors, and a coil wearing a coat of dust turns a struggle into a failure.

The manual gives the range of room temperatures the model is built for. If the garage falls outside it, a garage-rated refrigerator or a cooler spot may do more good than a new part, and we'll tell you if that's the situation.
