Microwave Oven Repair Service – MDTECH Technical Solutions

A malfunctioning microwave oven is a significant inconvenience, and depending on the fault, it can present serious electrical and safety risks due to its integrated high-voltage components. Whether you own a standard unit or a more advanced model with Convection, Inverter Technology, or Sensor Cooking, specialized knowledge is required for safe and effective repair.

MDTECH Technical Services is a premier C-20 licensed mechanical contractor serving the Los Angeles and Orange County areas. We provide the technical expertise and stringent safety protocols required for professional microwave oven repair, ensuring both functional restoration and complete electrical compliance.

Technical Solutions for Microwave System Failures

Microwave ovens operate using specialized, high-voltage electrical circuits. Our certified technicians address these complex systems with advanced diagnostic and safety procedures:

• Magnetron and High-Voltage System Diagnostics: When the microwave “runs but doesn’t heat,” the issue lies within the high-voltage circuit. We safely test the Magnetron, the Inverter Board (or Transformer), the high-voltage Diode, and the Capacitor. We replace failed components with new, correct-specification parts to restore optimal heating power.

• Control Board and Keypad Repair: We resolve issues involving unresponsive keypads, intermittent power, or system failure signaled by alphanumeric error codes. We audit and replace the primary PCB (Printed Circuit Board) to restore digital control logic and user interface function.

• Door Interlock Switch Restoration: The door interlock switches are critical safety mechanisms that prevent the unit from operating when the door is open. We test and replace these switches and adjust the door alignment to ensure secure closure and zero energy emission while the unit is running.

• Safety and Electrical Audit: We troubleshoot issues like tripping circuit breakers or sparking inside the cavity, addressing faulty high-voltage wiring, damaged waveguide covers, or short circuits.

The MDTECH Advantage for Electrical and Safety Compliance

Microwave repair involves unique electrical hazards. Choosing MDTECH guarantees a professional and safe service environment:

• C-20 Licensed Mechanical Mastery: Our specialized licensing ensures we operate with deep knowledge of high-voltage systems and the mechanical integrity of the appliance structure.

• Mandatory Radiation Safety Audit: Following any high-voltage or door component repair, we perform a mandatory microwave radiation leakage test using calibrated detectors to ensure the unit emits zero leakage above federal safety limits. We will not return an unsafe microwave to service.

• Safety Shut-Down Protocol: All work is performed only after the circuit breaker is secured and the high-voltage capacitor is safely discharged, eliminating electrocution risk.

• Genuine Component Usage: We prioritize the use of high-quality, specified components that meet the required electrical tolerances for safe operation.

Critical Indicators Your Microwave Needs Service

Address these issues immediately, especially those related to heating or the door mechanism:

1. Runs But Doesn’t Heat: Indicates a failure of the Magnetron or a component in the high-voltage circuit.

2. Sparks or Burning Smell: Suggests a damaged waveguide cover, internal debris, or a critical internal component failure. Stop using the unit immediately.

3. No Power/Intermittent Power: Often a sign of a failing control board, fuse, or thermal protection device.

4. Door Does Not Close Securely: A major safety hazard; the unit must not be operated if the door latch is compromised, as this risks radiation leakage.
