LG Microwave Repair in Silver Spring, MD

Many LG microwaves use an inverter board to power the magnetron instead of the heavy transformer found in older designs. The result is smoother low-power cooking, but it means a no-heat fault may be a board rather than a transformer or diode. Other LG models keep the traditional circuit. Over-the-range units are also the kitchen's hood, which brings the exhaust fan, the lamps and the grease screens into the picture, and some add convection with its own element and fan. The common complaints are a unit that runs without heating, a door switch that fails and takes the fuse with it, and a touchpad that stops responding. Inverter boards and capacitors can hold enough stored energy to injure someone long after the cord is out, which is why the cabinet should stay closed unless you know how to discharge them.

Where we start on this pairing: Inverter board or magnetron failed; Door switch blowing the fuse; Vent fan motor failed; Touchpad not responding; Turntable motor stalled.

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.

Over-the-range microwaves are the rule in Silver Spring's updated kitchens, from townhouses in Fairland to renovated ramblers in Wheaton, and they double as the only range hood. Grease and steam from the burners below wear out the fan, the light and the keypad along with the heating side. In a rented apartment the unit normally belongs to the owner, and a basic countertop microwave may not be worth a repair at all.

Gas ranges on Washington Gas are typical in the older houses of Woodside Park, Forest Glen and Four Corners, while the downtown towers mostly cook on electric and townhouses are a mix.

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.

Summer thunderstorms bring down lines around Silver Spring, and some outages run a day or more; the June 2012 derecho left parts of the region dark for days. Keep the refrigerator and freezer closed while it lasts. Federal food-safety guidance allows about four hours for a shut refrigerator, about 48 for a full freezer and about 24 for a half-full one.

What damages electronics is often the moment power comes back rather than the outage itself. An appliance that stays dark or throws a code afterwards can often be reset by switching its breaker off for a minute. If it doesn't recover, tell us about the outage when you book.
