Annandale notes
Microwave repair notes for Annandale kitchens
An Annandale request listed on this page, from September 2024, was a GE microwave that stayed completely dead even after it was unplugged and the breaker was reset. That narrows things down. A dead display usually means a blown line fuse, a failed door switch or the control board, and the fuse often blows because a door switch failed first.
Replacing only the fuse can work for a while, but if a door switch caused it, the new fuse will blow too. The technician tests the switches and the board before replacing anything.
A completed repair in Annandale Terrace in June 2025 shows the other common failure. An LG over-the-range unit ran with a loud buzz but didn't heat, and the technician replaced a shorted high-voltage diode and the magnetron. A loud buzz with no heat usually points to the high-voltage side: the diode, the capacitor or the magnetron.
Over-the-range microwaves get their power from an outlet in the cabinet above. If that circuit has tripped, the microwave can look dead, so check the breaker labeled for the kitchen or the microwave. A door that no longer closes square, from a worn latch or hinge, is hard on the door switches and worth mentioning.
Don't open the case. The capacitor inside can hold a charge after the unit is unplugged. Countertop microwaves are often cheaper to replace than repair, and we'll say so on the phone. Over-the-range and built-in units usually justify the repair, since a new one has to fit the same space and wall plate, and the cost guide shows typical ranges.
When you book, send the model number, usually on a label inside the door opening, and say whether the unit is over-the-range or built-in, since those take longer to open. Clear the counter and the range below. In an Annandale condo building, add any contractor hours or sign-in rules to the booking notes.

Frequently asked questions
Microwave Repair in Annandale, VA FAQ
Can someone come fix my microwave today in Annandale?
We're based in Alexandria, about 8 miles from Annandale. Same-day and next-day appointments are available when the technician route has open windows; call or book online for the earliest option. Appointments cost the same on weekdays, evenings and weekends - our hours run 8 AM to 10 PM Monday through Saturday and 10 AM to 10 PM on Sunday, all at one standard rate.
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.
How much does it cost to fix a microwave in Annandale?
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.
What microwave problems do you fix in Annandale?
Online microwave repair requests from Annandale have been for no power. 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.
My microwave is completely dead. What's the likely cause?
A blown line fuse is common, often caused by a failing door switch. The control board can also fail, especially after a power surge. The Annandale GE request we list was dead even after a breaker reset.
Can I replace the microwave fuse myself?
It's not recommended. The fuse sits near the high-voltage parts, and the capacitor can hold a dangerous charge even when unplugged. And if a door switch caused the fuse to blow, a new fuse won't fix the real problem.
Should I try to fix the microwave myself first?
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.
My over-the-range microwave buzzes loudly but doesn't heat. Is it worth repairing?
On an over-the-range or built-in unit, usually yes. A loud buzz with no heat typically means a failed high-voltage diode, capacitor or magnetron. That was the Annandale Terrace job in June 2025 on an LG over-the-range model, which needed a new diode and magnetron. A magnetron costs more than a diode, but it often still beats buying a new unit that has to fit the same wall plate and cabinet. Stop using it until the visit.
What should I do before an over-the-range microwave repair in my Annandale kitchen?
Clear the countertop and the range below, and empty the cabinet above if you can, since the unit is bolted through that cabinet and some repairs mean taking it down from its wall plate. Send the model number and the symptom when you book so the technician can bring the likely parts. If the microwave sparks or smells burnt, unplug it or switch off its breaker and leave it off.
