About Our Microwave Repair Service
A microwave that runs but does not heat food, or one that produces sparks during operation, usually indicates a specific internal fault rather than a general malfunction. Common causes include a failing magnetron, which is responsible for generating heat, a worn door switch that prevents proper operation, or a damaged waveguide cover that can lead to arcing inside the cavity. Because microwaves contain high voltage components that can retain an electrical charge even after the appliance has been unplugged, they are not suitable for casual do-it-yourself repair. These stored charges can present a serious safety risk if the unit is opened without proper procedures. Our technicians follow appropriate discharge procedures before accessing internal components. Once the unit is safely opened, they test each part methodically to identify the exact source of the problem and determine the necessary repair.
Signs You May Need Microwave Repair
- The microwave runs but food comes out cold or barely warm
- Sparking or arcing visible inside the cavity during operation
- The turntable does not rotate during a cycle
- The keypad is unresponsive or certain buttons do not work
- A burning or electrical smell coming from the unit
- The display is blank even though the unit is plugged in
Our Microwave Repair Process
- We ask what happens when the microwave is started and whether any sparking has occurred.
- The technician safely discharges the high voltage capacitor before inspecting internal components.
- The magnetron, door switches, waveguide cover, and control board are tested individually.
- The unit is repaired, reassembled, and tested to confirm safe and consistent heating.

Frequently Asked Questions
We do not recommend it. Microwaves store high voltage in the capacitor even after being unplugged, and improper handling can cause serious injury. This is a job for a trained technician.
Sparking is often caused by a damaged waveguide cover, metal contact inside the cavity, or a failing magnetron. It should be addressed before continued use.
In most cases yes, though some repairs may require removing the unit from the cabinet for full access to internal components.
Customer Reviews
Was hesitant to keep using it after it started sparking, glad I called instead of trying to fix it myself.
Turntable motor was replaced and it works like new again.
Technician explained the high voltage risk clearly, which I appreciated.
