Licensed Microwave Oven Repair Services – MDTECH Technical Solutions

MDTECH Technical Services specializes in professional, licensed diagnostics and repair of all brands and models of residential and commercial microwave ovens within the Greater Los Angeles and Orange County, California areas.

Microwave ovens rely on a complex high-voltage circuit to generate heat, making them inherently dangerous to service without professional training. Failure of key components can result in a dead unit, no heat, or unsafe operation. As C-20 licensed mechanical contractors, MDTECH provides certified expertise and strictly adheres to safety protocols for every repair.

I. Comprehensive Microwave Oven Repair Services

We offer full-spectrum service to address all functional failures, ensuring both effective repair and user safety:

A. High-Voltage and Heating Circuit Repair

This is the most critical area of service, requiring specialized knowledge and tools to ensure safety.

• No Heat Condition: We safely discharge the capacitor and test the Magnetron, high-voltage diode, and capacitor. These are the core components responsible for heating food. Replacement restores the unit’s primary function.

• Total Power Failure: We diagnose why the unit is completely dead, typically by checking and replacing the thermal fuses (often tripped by overheating) or the main line fuse (tripped by electrical surges).

B. Safety and Control System Service

Microwaves rely on precise safety systems to prevent operation when the door is open.

• Door Interlock Repair: We test, adjust, and replace the door interlock safety switches and the latch mechanism. Proper functioning of these switches is non-negotiable for safe operation.

• Control Panel Failure: We repair or replace faulty electronic control boards or touchpad membranes to resolve issues such as non-responsive buttons, blank displays, or units stuck in “Demo Mode.”

C. Mechanical and Noise Resolution

We restore smooth, efficient operation for consistent cooking results.

• Non-Rotating Turntable: Replacing the failed turntable motor or the drive coupling that links the motor to the glass tray.

• Loud Noise/Buzzing: Diagnosing and replacing worn components such as the cooling fan or stirrer motor (in models without turntables) to eliminate excessive noise.

II. MDTECH Safety and Licensing Assurance

Due to the persistent electrical hazard posed by the high-voltage capacitor, self-repair is strongly discouraged. Our C-20 licensing guarantees that all internal microwave oven repair is performed by qualified technicians trained to discharge high-voltage components, replace specialized parts safely, and confirm that the unit’s electromagnetic containment remains intact.
