Looking for microwave oven repair — not heating, sparking inside, beeping but won't start, or the door won't latch? We diagnose built-in, over-the-range, countertop, and drawer-style microwave ovens same-day, from everyday GE and Samsung units to Wolf, Miele, and Thermador speed ovens.
Every install type and brand, in your home, same-day when possible
GE, Samsung, and Whirlpool OTR microwaves that double as the range hood and vent fan. Half of "the microwave broke" calls on these turn out to be the vent motor or cavity light, not the magnetron — we test both separately.
Wolf, Thermador, Miele, and GE Monogram convection speed ovens built into cabinetry above or beside the wall oven.
Everyday countertop units from every major brand — interlock switches and the high-voltage diode are the two most common failures we find on these.
Under-counter drawer units built into kitchen islands, common in newer remodels — different latch mechanism from a door-style unit, same interlock-switch logic underneath.
Viking, Miele, and Gaggenau speed ovens common in newer OC kitchen suites. See all brands we service.
Most microwave calls are also oven households. See our oven & range repair guide for igniter, element, and control-board diagnostics.
We test the door interlock switches first — most microwaves wire two or three of them in series, and if one is worn or misaligned the unit will hum, the light will come on, the turntable will spin, and the magnetron still never fires because the safety circuit never closes. A switch is a $90–$150 fix. If the switches test fine and you hear a loud buzz with zero heat, that's usually the high-voltage diode, which fails open and stops the magnetron from ever getting the DC voltage it needs, $110–$180. Only after those two check out do we test the magnetron itself; on a microwave more than 8–10 years old, a failed magnetron ($220–$350 with labor) is the point where we'll tell you straight that a new unit is the better spend.
Same interlock switch system as the no-heat cases above, but coming from the mechanical side — worn hinges or a bent latch hook throwing the switches out of alignment instead of a switch failing electrically on its own, usually $90–$160. On over-the-range units, if the complaint is really about noise or a smell rather than heating, we also check the vent fan motor and the grease filter before touching the microwave circuit itself — these share a control board with the cooking function but fail independently of it.
Almost always the mica waveguide cover, the small panel inside the cavity that shields the waveguide from grease splatter. It thins out over years of cooking and starts arcing at the weak spot; the part itself is inexpensive, and total repair including labor usually runs $100–$180 depending on how buried it is in that model. Stop using the microwave the moment you see arcing — running it further can damage the magnetron and turn a cheap fix into an expensive one.
Usually the touchpad membrane wearing out from years of use, or the main control board behind it. A control board swap is the priciest microwave repair we do — boards are model-specific and have to be ordered, $150–$280. On built-in and speed-oven models this is also the point where cabinetry access matters: some installs require pulling the whole unit forward on its mounting rails to reach the board, which we budget extra time for rather than quoting it like a countertop swap.
We repair built-in, over-the-range, countertop, and drawer-style microwaves throughout Orange County — GE Monogram, Bosch, Samsung, Sharp, Panasonic, Viking, and every other major brand. Most microwave repairs run $90–$350 and finish in a single same-day visit; the $95 diagnostic fee is waived if you go ahead with the repair.
Every visit starts with a $95 diagnostic, waived if you go ahead with the repair, and we give you an upfront quote before any work starts — no surprise invoice. Most microwave repairs run $90–$350 depending on the part: door interlock switches and the mica waveguide cover are on the lower end and usually finish in one visit since we stock them on the truck; the high-voltage diode and touchpad sit in the middle; magnetrons and model-specific control boards run highest, especially on built-in or speed-oven units that have to be ordered. Whether a repair is worth it also depends on the unit's age and mounting — a $90–$180 switch or waveguide cover on a microwave under 8 years old is an easy yes, but a failed magnetron on a countertop unit past 10 years is often cheaper to replace outright than repair; on built-in and over-the-range models sized to a specific cabinet cutout, repair usually wins even at the higher end because a mismatched replacement means cabinetry work too.
Searching for microwave oven repair near me? LEVKO sends a technician to your home anywhere in Orange County, and call or text before noon gives you the best chance of a same-day visit. We work from Lake Forest and cover the county from Fullerton down to Laguna Niguel — there is no shop to drive to, and you don't have to unmount an over-the-range unit or carry a built-in out of its cabinet.
Most microwave failures are cheaper to fix on site than to replace: we carry door interlock switches, mica waveguide covers, and touchpad membranes on the truck, so the common repairs finish in one visit. When a part is model-specific, like a magnetron or a control board on a built-in or speed-oven unit, we tell you on the spot and order it the same day. Every repair carries a 90-day parts and labor warranty, and the technician who diagnoses the problem is the one who fixes it.
The model number on the rating label (inside the door frame on most units, behind the grease filter on some over-the-range models) and what it does: no heat, arcing, dead keypad, or door problem. Unplug it, or switch off the breaker for a built-in, if you see sparks or smell burning — a microwave that arcs can destroy its own magnetron within minutes. If it is a countertop unit more than 10 years old, tell us its age when you call; a failed magnetron on one of those is often cheaper to replace than to repair, and we'll say so.

Most repairs run $90–$350 depending on the part — door interlock switches and the mica waveguide cover on the lower end, magnetrons and control boards on the higher end. $95 diagnostic, waived when you proceed with the repair.
We test the door interlock switches first, then the high-voltage diode, then the magnetron itself, in that order of likelihood and cost. We test each in sequence rather than replacing the most expensive part first.
Almost always the mica waveguide cover thinning out and arcing at the weak spot, usually $100–$180 to fix. Stop using the microwave until it's replaced — running it further can damage the magnetron.
Usually yes under 8-10 years old — built-in and OTR units are sized to a specific cabinet cutout, so a mismatched replacement often means cabinetry work on top of the appliance cost. Past 10-12 years, especially for a failed magnetron, we'll tell you honestly when replacement is the better spend.
