LaCanche Microwave Repair

We provide specialized diagnostic and repair services for the high-end built-in microwaves often found in custom LaCanche kitchen installations. Our team offers safe, reliable solutions for complex high-voltage microwave circuitry.

While LaCanche is famous for their handcrafted French ranges like the Cluny, Sully, and Chagny, they do not manufacture microwave ovens. However, homeowners in the Pacific Northwest who invest in these bespoke ranges often install high-end, custom-paneled, or premium built-in microwaves to match their kitchen design. When these units malfunction, you need a technician who respects the precision of luxury cabinetry. We are experts at removing heavy built-in units from custom millwork without damaging your home's finish. Proper airflow is essential for these units, and we verify that your trim kits and ventilation paths are clear. In our experience, if airflow is restricted—a common issue in tight kitchen designs—the magnetron can fail prematurely. We assess the entire installation to ensure that heat from your LaCanche range isn't affecting the microwave's sensitive electronics. Our team uses protective gear and specialized tools to ensure our work remains non-invasive to your kitchen environment.

Repairing a microwave is a hazardous task that should never be attempted by a homeowner. These appliances contain high-voltage capacitors that can hold a lethal charge exceeding 2,000 volts, even after the power is disconnected. Our technicians are equipped with high-voltage probes, bleeder resistors, and insulated gear to manage these circuits safely. We conduct thorough testing to determine if the failure is in the magnetron, the high-voltage diode, the door interlock micro-switch assembly, or the main control board. We also perform microwave leakage testing to ensure the Faraday cage mesh and door seals are secure, protecting your home from RF energy leaks. For modern units with inverter boards that provide steady power, we use precise multi-meter testing to verify performance. Our $90 diagnostic fee covers this complete, safety-focused inspection.

When you book with A-Fix Service, our technician arrives ready to troubleshoot. We verify the power supply and safely discharge high-voltage components before starting any internal work. We check the magnetron for continuity and inspect the primary, secondary, and monitor door interlock switches, which are frequent failure points. Because we service over 247 appliance brands, our vans are stocked with universal micro-switches, high-voltage diodes, capacitors, and line fuses, allowing us to fix many issues on the first visit. For built-in models, repairing your existing unit is usually the smartest choice to avoid the expense of cabinet modifications. We perform a full thermal test with a water load to confirm the magnetron is outputting the correct wattage and that the cooling system is functional. The $90 diagnostic fee is waived if you move forward with our repair quote.

Frequently Asked Questions

How much does it cost to repair a built-in microwave?

Pricing depends on the part. Simple repairs like a fuse or door switch might be $150-$250, while major components like an inverter board or magnetron can be $300-$500+. We charge a $90 diagnostic fee to provide an accurate estimate.

What is your warranty on microwave repairs?

We stand behind our work with a 1-year warranty covering both parts and labor. If the specific part we installed fails during that time, we will replace it for free.

Should I repair or replace my high-end built-in microwave?

Repairing is almost always the better option. Replacing a custom-fitted unit often requires expensive carpentry to adjust your cabinetry. Most internal microwave parts are standard and highly repairable.

Can I test the microwave's internal fuse myself?

Absolutely not. The high-voltage capacitors inside can store a lethal charge of up to 4,000 volts. Our technicians use professional grounding equipment to discharge the unit before testing.

How quickly can you service my microwave?

We generally offer same-day or next-day appointments. Please call (800) 200-2349 to schedule a technician.

Do you carry microwave parts on your trucks?

Yes, we stock common items like capacitors, high-voltage diodes, door micro-switches, and magnetrons. If a specific control board is required, we can typically obtain it within 2-3 business days.
