We repair all types of microwaves and all major brands:

Built-In, Over-the-Range & Combo Microwaves

We specialize in repairing built-in microwaves, over-the-range units, and microwave/oven combo appliances. These installations are often more complex and costly to replace—repair is usually the best option.

Built-In Microwave

Built-in microwaves are installed into cabinetry or a wall niche for a seamless kitchen look. They require exact dimensions and proper electrical and venting. When yours stops heating, the display fails, or the door won't latch, replacing the unit is expensive and may require cabinet work. Our technicians repair built-in microwaves from GE, Bosch, Samsung, LG, KitchenAid, and other brands—including magnetron, control board, door switches, and vent fan issues. We can often complete the repair on-site the same day.

Microwave / Oven Combo Unit

Combination units combine a microwave with a convection or traditional oven in one appliance. When the microwave side isn't heating, the oven element fails, or the control panel acts up, you don't have to replace the whole unit. We diagnose and repair both the microwave and oven functions: magnetron, heating elements, control boards, door latches, and fans. Repairing a combo unit is typically more economical than buying a new one, and we carry experience with major brands' combo models.

Over-the-Range Microwave

Over-the-range (OTR) microwaves mount above your cooktop and double as a vent hood. They have more components than countertop models: exhaust fan, vent duct, under-cabinet lighting, and often a charcoal filter. We repair all OTR issues—not heating, fan not venting, lights not working, door and latch problems, and control panel failures. Proper mounting and venting are important for safety and performance; our technicians handle repairs without compromising the installation. Same-day service is available for over-the-range microwaves throughout San Diego County.

Microwave Safety Warning

Important: Microwaves contain high-voltage components that can hold a dangerous electrical charge even when unplugged. Never attempt DIY repairs on microwaves - always hire a professional technician.

Repair vs. Replace Decision

Consider repair if:

• Your microwave is built-in or over-the-range (expensive to replace)
• The microwave is less than 5 years old
• Repair cost is less than 50% of replacement

Consider replacement if:

• Countertop model older than 8-10 years
• Magnetron failure on an older unit
• Multiple components need replacement
• Repair cost exceeds 50% of new microwave price
