Microwave Repair Riverside | Not Heating, Sparking

Why is my microwave sparking or not heating?

In most cases, microwave sparking is caused by food debris or metal objects inside the cavity, or a worn waveguide cover. If your microwave runs but doesn't heat, it's usually a failed magnetron (the component that generates microwaves) or high-voltage diode.

"Many people consider replacing their entire microwave when it stops heating, but often it's a repairable component. We perform thorough diagnostics to identify the exact cause before any work begins."

Safety First: NEVER operate a sparking microwave! Sparks can damage internal components and create safety hazards. Unplug immediately and call for professional diagnosis.

Built-in vs Countertop Models: Built-in microwaves (Viking, GE Monogram, Thermador) often have unique installation challenges including ventilation, electrical connections, and mounting brackets. We specialize in these complex systems.

Value of Professional Repair: For high-end built-in microwaves costing $1,000+, professional repair is often more economical than full replacement. We provide transparent quotes after diagnosis so you can make an informed decision.
