GE Appliances Microwave Repair in Silver Spring, MD

In most local kitchens a GE microwave hangs over the range and doubles as its exhaust hood. That means two appliances share one box: the cooking side, with its high-voltage transformer, capacitor, diode and magnetron, and the hood side, with a blower, cooktop lights and metal filters that should be washed regularly. A unit that hums and turns the plate but leaves coffee cold has lost something in the high-voltage chain. A unit that goes dark after the door is slammed has probably blown its fuse through a failing interlock switch. Advantium speed-cook models add halogen lamps and convection to the mix, which lengthens both the parts list and the diagnosis. The capacitor can hold a dangerous charge long after unplugging, so leave the cover on. Removing an over-the-range unit takes two people and access to the bolts inside the upper cabinet.

Where we start on this pairing: Magnetron burned out, no heat; Door switch failure blowing the fuse; Vent fan bearing noisy or seized; Touch pad not registering presses; Advantium halogen lamp burned out.

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.

Heat-pump and condenser dryers, and all-in-one washer-dryers, need no outside vent, but their lint screens, condensers and drain filters want cleaning far more often than owners expect. Most slow-drying complaints on these end in a cleaning rather than a part.

Check the manual for where the extra filter or condenser is, rinse it on a regular schedule, and cycle times usually return to normal.
