MDTECH Technical Services specializes in professional, licensed diagnostics and repair of residential microwave ovens and combination microwave-hood units. We serve the Greater Los Angeles and Orange County, California areas.

Microwaves operate using high-voltage components (magnetron, capacitor, transformer) and should never be serviced by an untrained individual due to significant electrical hazards, even when unplugged. As C-20 licensed mechanical contractors, MDTECH provides certified electrical and mechanical expertise for safe, effective microwave repair.

Technical Solutions for Common Microwave Failures

We address the core electrical and mechanical faults that cause microwaves to fail:

1. No Heat, Light, or Power (Electrical Failure)

• The Issue: The microwave runs (fan/turntable moves) but does not heat food, or the unit is completely dead (no lights, sounds, or display).

• The MDTECH Fix:

  • No Heat: We test and replace the magnetron (the component that generates the radio waves), the diode, and the high-voltage capacitor/transformer. This high-voltage work is performed with strict safety protocols.

  • No Power: We check and replace the thermal fuses (often tripped by overheating) or the main fuse within the control board, restoring power to the unit.

2. Turntable and Door Mechanism Failures

• The Issue: The turntable plate does not spin, or the door does not latch correctly, which prevents the microwave from starting due to the safety switch being disengaged.

• The MDTECH Fix:

  • Turntable: We replace the turntable motor or the drive coupling underneath the plate.

  • Door: We adjust or replace the door latch mechanism and the crucial interlock safety switches. These switches must function perfectly to prevent the magnetron from firing while the door is open.

3. Control Panel and Display Issues

• The Issue: The touchpad buttons do not respond, or the display is blank or erratic.

• The MDTECH Fix: We test the membrane switch panel and the main control board. We replace the failed component to restore full functionality and programming control.

MDTECH Safety and Licensing Assurance

Repairing microwave ovens involves handling circuits that store a lethal electrical charge, even after being unplugged. Our C-20 licensing guarantees that all diagnostics and component replacement are performed by qualified professionals trained in high-voltage safety and appliance mechanical standards.
