When searching for a “microwave oven repair shop,” clients are seeking certified expertise and convenience. MDTECH provides a superior, licensed service model that eliminates the need to transport your appliance, offering expert repair right in your home. As C-20 licensed mechanical contractors, we guarantee strict safety protocols when dealing with the hazardous high-voltage components of a microwave.

MDTECH’s Advantage Over Traditional Repair Shops

We deliver the capability and trust of a specialized repair center, but with the added convenience of in-home service:

1. High-Voltage Component Expertise

The primary function of a microwave requires dealing with lethal electrical charge held in components like the high-voltage capacitor and the magnetron. We provide expert service for:

  • No Heating Issues: Safely testing and replacing the Magnetron, high-voltage diode, and capacitor—the core heating circuit components.

  • Power Failures: Diagnosing and replacing blown thermal fuses or main line fuses, often caused by overheating or electrical surges.

2. Safety and Control System Repair

Microwave operation relies heavily on safety interlock systems. We ensure your unit operates safely and correctly:

  • Door Switch Replacement: Precise adjustment and replacement of door interlock safety switches. If these fail, the microwave will not start or heat, protecting the user from microwave emission.

  • Control Panel Issues: Troubleshooting and repairing the electronic control board or touchpad membrane to fix display malfunctions or non-responsive buttons.

3. Mechanical System Restoration

We resolve noise and rotation issues that compromise cooking quality:

  • Turntable Repair: Replacing the seized turntable motor or the broken plastic drive coupling to ensure food heats evenly.

  • Noise Reduction: Identifying and replacing faulty cooling fans or stirrer motors to eliminate loud buzzing or grinding sounds.

Our Commitment to Service

Choosing MDTECH means opting for certified, licensed professionals who prioritize safety and lasting quality in every repair, often exceeding the standards of a general repair shop.
