Atosa Freezer Repair in Bethesda & Chevy Chase, MD

An Atosa freezer is built like the refrigerator but runs its coil below freezing, so it has to melt that frost off regularly. A timed heater does the melting, and a sensor on the coil tells the control when to stop. When the heater burns out, frost thickens each day until air can't get through and the box warms. Melt water leaves through a drain line, often with its own heater, and if that line freezes, the water refreezes inside the cabinet as a sheet of ice on the floor. Worn gaskets let humid air in, and frost forms around the door frame. In a hot kitchen with a dirty condenser, the compressor overheats and trips on its overload, so the freezer runs in fits and starts.

Where we start on this pairing: Defrost heater burned out; Drain line frozen, ice on the cabinet floor; Coil iced solid; Frost around the door from a worn gasket; Compressor tripping on overload.

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.

Few Bethesda condos have room for a separate freezer, so the freezer is usually a drawer in a French-door fridge or one column of a built-in pair. Houses in Wildwood, Ashburton and Wood Acres are different: a chest or upright often stands in the basement or garage, and in a humid July a garage freezer barely rests. After a summer thunderstorm takes out Pepco service, it's the appliance people check last and worry about most.

Refrigerators here run from panel-fronted built-ins in rebuilt Chevy Chase and Bradley Hills kitchens to counter-depth units squeezed into condo galleys off Wisconsin Avenue and Woodmont Avenue.

Whatever the brand, the freezer symptom that misleads people most is a slow thaw that nobody notices, because most chest freezers have no alarm.

Locally, what we watch for most on a freezer is garage freezers fighting summer heat, and basement freezers standing on concrete that stays damp from June to September.

Three complaints come up again and again with gas appliances: the oven igniter glows and nothing lights, a cooktop burner ticks without catching, and a gas dryer turns but never warms. Most trace to a worn igniter, a weak valve coil or a flame sensor, all ordinary parts.

Gas piping and the shutoff valve behind the appliance aren't ours to work on; if we see a problem there, you'll be told to call a licensed gas fitter.
