Service
Wolf microwave & microwave drawer repair across the SF Bay Area — not heating, drawer won't open, control faults fixed. Call (650) 668-1554.
A Wolf microwave is built to disappear into the cabinetry and pull its weight as a real cooking appliance, not a reheating box. The built-in convection models bake and roast as well as they reheat, and the microwave drawer slides into a base cabinet where a swing door would never fit. When one of these stops heating or the drawer refuses to glide, the kitchen loses a piece it was designed around.
We are an independent Bay Area repair company based in Los Gatos, and we have worked on high-end cooking appliances since 2005. To be clear, we are not a manufacturer-authorized or factory-certified Wolf service center; we are an experienced independent shop that sees these units regularly across the Peninsula and South Bay. That distinction matters less than knowing how a sealed magnetron circuit or a drawer carriage actually fails.
The rest of this page walks through the Wolf microwaves and microwave drawers we service, why a unit stops heating and the lethal high-voltage parts behind that symptom, the mechanical faults unique to the drawer design, and how to book a visit. The recurring theme: the cooking cavity is approachable, but the high-voltage section is not, and we treat that line as non-negotiable.
We service the full Wolf microwave lineup, including the built-in convection microwaves in the M Series and the older MC24 and MC30 models, the standard built-in microwaves, and the microwave drawer in both MD24 and MD30 widths. The convection models add a turntable and a convection fan on top of the usual microwave hardware, so they fail in more ways than a plain unit and reward a technician who knows which symptom belongs to which subsystem.
The microwave drawer is its own animal. Instead of a hinged door, the whole cavity rides out on a motorized carriage, opened and closed at the touch of a panel or a sensor. That gives you a drawer mechanism, an open-close motor, and position sensing as failure points that a conventional microwave simply does not have. We keep both families in mind from the first question we ask you.
When a Wolf microwave runs, lights, and turns the turntable but leaves the food cold, the cooking energy is missing and the fault almost always sits in the high-voltage section: the magnetron that generates the microwaves, the high-voltage capacitor and diode that feed it, or the door interlock switches that must all confirm the door (or drawer) is shut before power is allowed. A heating complaint can also trace to the control board or the touch membrane failing to command the cycle, which is why diagnosis comes before any part.
Here is the part we will not soften: the high-voltage capacitor stores a dangerous, potentially lethal charge even after the unit is unplugged, and the magnetron circuit is never owner-serviceable. This is not a panel anyone should open at home, and it is the single biggest reason a no-heat microwave needs a technician with the training and tools to discharge and test it safely rather than a DIY attempt.
The microwave drawer earns its convenience with extra moving parts, and those parts are where MD24 and MD30 units tend to act up. The drawer open-close motor drives the cavity in and out, and the mechanism relies on position sensing and the door interlock switches reading correctly at the closed position. When the motor weakens, a roller or track binds, or a switch stops confirming the closed state, the drawer may refuse to open, stall partway, fail to seal, or simply not start a cycle because the controller never sees a safe, closed cavity.
We diagnose the drawer as a distinct system from the cooking electronics. Sometimes the cure is in the carriage and motor; sometimes the drawer is mechanically fine and the real fault is an interlock or the control board misreading position. Sorting that out on the first visit is what keeps a drawer repair from turning into a guessing game with expensive assemblies.
We carry common microwave and drawer parts on the truck, and less common Wolf components are ordered promptly so we can return and finish the job. We work from your model and serial number to match the right magnetron, motor, switch, or board to your exact unit rather than guessing at a generic substitute.
We are Los Gatos-based and cover the greater Bay Area, from Silicon Valley and the Peninsula out to the East Bay, San Francisco, and Marin. Book a visit through our online calendar or call (650) 668-1554, and have your model and serial number from the rating plate handy so we arrive ready.
FAQ
Usually yes, because a built-in convection microwave or microwave drawer is sized and trimmed to a specific cabinet opening, and replacing it can mean cabinetry or panel work on top of the appliance cost. If the fault is a single part — a magnetron, a door interlock switch, a drawer motor, or a control board — a repair typically costs a fraction of a like-for-like replacement and keeps your cabinetry intact. We give you the diagnosis and an honest read on repair versus replace for the age and condition of your unit before any work begins.
A microwave that lights up and spins but leaves food cold has lost its cooking energy, which points to the high-voltage section — most often the magnetron, the high-voltage capacitor or diode, or a door interlock switch not confirming the door or drawer is closed. It can also be a control board or touch membrane that never commands the heat cycle. None of this is owner-serviceable: the high-voltage capacitor holds a dangerous charge even unplugged, so this needs a technician to discharge and test it safely.
On an MD24 or MD30, a drawer that won't open or stalls partway usually means the open-close motor is weak, the drawer mechanism or a track is binding, or a position switch isn't reading correctly. Try a power-cycle first — switch off the breaker for about a minute, then restore it — in case the controller simply lost its place. If the drawer still won't move or seal, stop forcing it and book a technician, since the carriage and switches are internal parts.
No. The magnetron sits in the high-voltage section alongside the high-voltage capacitor and diode, and that capacitor can store a potentially lethal charge even after the unit has been unplugged. There is no safe owner procedure here. This is exactly the kind of repair that needs a technician with the tools to discharge the capacitor and test the circuit, and we do not recommend opening that panel under any circumstances.
Yes. We service the built-in convection microwaves in the M Series and the older MC24 and MC30 models, standard built-in microwaves, and the microwave drawer in MD24 and MD30 widths. Convection models add a turntable and convection fan, and the drawers add a motor and mechanism, so we diagnose each by its specific design rather than treating every microwave the same.
Most likely, yes. We are based in Los Gatos and serve the whole San Francisco Bay Area, including San Francisco, the Peninsula, Silicon Valley and the East Bay. Call (650) 668-1554 or book online, and we will confirm coverage for your address and schedule a visit.
No. We are an independent appliance-repair company and are not manufacturer-authorized or factory-certified by Wolf. We have worked on high-end Wolf cooking appliances, including built-in and convection microwaves and microwave drawers, throughout the Bay Area since 2005, and we use parts matched to your specific model — but we are not affiliated with or endorsed by the manufacturer.
Reviews
“The touch panel on our Wolf microwave drawer in Burlingame went unresponsive and the drawer wouldn't latch closed to start. Jim diagnosed a failed membrane switch and a door interlock that wasn't confirming closed, replaced both, and tested the lockout safety before handing it back. Punctual and explained why it refused to run.”

“Our built-in Wolf microwave in Mountain View was sparking inside and smelled scorched whenever it ran. Steve found the waveguide cover had charred through and the turntable motor had seized, replaced the cover and motor, and checked for arcing damage to the cavity before clearing it for use. Honest, tidy, and reassuring about the safety side.”
Sandra W.Mountain View · Wolf · built-in microwave
“Our Wolf built-in microwave in Palo Alto would run and hum but never actually heat anything. Steve confirmed it was a failed magnetron, discharged the high-voltage capacitor safely first, and replaced the magnetron and a blown line fuse the same visit. He was clear that this is not a part to poke at yourself, and it's heating like new again.”
Vivian L.Palo Alto · Wolf · built-in microwave
“The microwave drawer in our Los Altos kitchen stopped sliding open at the touch of the panel and would stick halfway. Dave traced it to a worn open-close motor and a binding carriage rail, replaced the motor and re-aligned the drawer so it glides cleanly now. Careful work in a tight cabinet and he left no marks on the surround.”

“Our Wolf convection microwave in Saratoga heated fine on microwave mode but the convection bake side wouldn't get hot. Steve found a failed convection element and a stuck relay on the control board; the element had to be ordered so it took a return visit, but he only billed the part the second time. Roasts evenly again.”
