A Jenn-Air microwave had a dead interior light (an over-the-range unit that has to come off the wall to service).
What our technicians usually find: the bulb or its socket.

In McLean's custom kitchens, the microwave is more often built into a wall cabinet or set into the island as a drawer than hung over the range. Those units are expensive to replace and have to match their cutout and trim kit, so repair is usually the sensible route. Speed ovens, which pair a microwave with convection, often sit beside the double wall ovens in these kitchens.
When a microwave runs, lights up and turns but leaves food cold, the high-voltage side has failed, usually the magnetron, the diode, the capacitor or a fuse. That capacitor can hold a dangerous charge even when the unit is unplugged, so the cover should stay on. When the unit is completely dead, a blown line fuse, a door switch or the control board is the more likely cause.
Speed ovens are repaired the same way on the microwave side, with a convection element and fan added to the list. If the speed oven in your McLean kitchen heats in microwave mode but not on convection, or the reverse, tell us which, since it narrows the diagnosis. Drawer models also have a motor and gear drive that open and close the drawer, and those wear with use.
A nearby request in the cards below, from Potomac, Maryland, shows a common catch. A Jenn-Air over-the-range microwave there had a dead interior light, and on many over-the-range units that light can only be reached by taking the microwave off the wall. That is a two-person job on a heavy unit, so if anything else about the microwave needs attention, it makes sense to fix it on the same visit.
Of the usual parts, door switches, diodes and fuses cost the least, and even a magnetron on a built-in normally comes in under a new unit plus its trim kit. Countertop microwaves are the exception: they are usually cheaper to replace than repair, and we don't service them. Typical ranges are in our repair cost guide.
At booking, give us the brand and the model number, found on a label inside the door frame or on a side wall of the cavity, and say whether the unit is a wall built-in, a drawer, a speed oven or over the range. For a wall unit, clear the counter below in case it has to slide out. Many McLean houses sit on long or gated driveways, so add the code and parking notes.

We're based in Alexandria, about 11 miles from McLean. Same-day and next-day appointments are available when the technician route has open windows; call or book online for the earliest option.

Many microwave repairs are completed in a single visit once the technician has diagnosed the fault and confirmed the parts on hand. If a specific part has to be ordered, we schedule a short return visit to finish the job.
Appliance Surgeon charges $75 for the diagnostic visit, or $115 for a double unit (such as a double wall oven, washer-dryer combo or stacked laundry), and the fee is credited toward the repair if you approve the quote. Labor starts at $200 and stays there on about 9 in 10 repairs; more complex jobs can reach $450. Parts are extra and listed in the quote. Door switches and diodes are inexpensive; a magnetron costs more but usually still beats replacing a built-in unit and matching the cabinetry. We quote after diagnosis, before any work - and the high-voltage interior is exactly why this is never a do-it-yourself estimate. Typical price ranges by appliance are in our appliance repair cost guide.
Common calls include microwave not heating, turntable not moving, sparking inside, door switch failure, control panel issue and unusual noise. The exact cause is confirmed during diagnosis.
On many models the interior light is reached by removing the microwave from the wall, which is a two-person job on a heavy unit. The cooktop lights underneath are usually easier. A Jenn-Air in one of our listed requests had exactly this issue.
We can. The microwave side uses the same high-voltage parts as any microwave, and the convection side adds an element and a fan. Tell us the brand and model when you book so we bring the right parts.
Only two checks are safe: the outlet and breaker, and whether the door closes fully. Stop there - the high-voltage capacitor inside holds a dangerous charge even when the microwave is unplugged, which is why this is the one appliance we tell everyone never to open.
Usually. Drawer microwaves open and close with a motor, gears and a latch, and a stall partway often traces to one of those, a door switch, or something caught in the track. Check that nothing is blocking the drawer and that the control lock is off. If it still sticks, book a visit rather than forcing it, because pushing against the motor can strip the gears. Have the model number ready, since drawer parts are specific to each line.
In most cases, yes. A magnetron is one of the more expensive microwave parts, but a built-in has to match its cabinet cutout and trim kit, so a new unit often costs more and can mean cabinet work. The technician first confirms the magnetron is really the fault, since a diode, capacitor or fuse can cause the same no-heat symptom for less, and you approve the quote before any work.
