Respect The Voltage

Microwaves carry lethal voltage even when unplugged. We teach you the professional protocols to discharge capacitors and diagnose safely.

No Heat / Humming

The light is on, the table turns, but the food is cold. Is it the Magnetron, Diode, or Capacitor? We teach you to test the “Doubler Circuit” with confidence.

🛑

Runs Then Stops

If a microwave runs for 2 seconds and stops, it’s often a Door Interlock issue. We break down the complex timing of Primary, Secondary, and Monitor switches.

🔌

Dead / No Power

Stop blindly throwing fuses at the unit. We teach you to trace the voltage drop through the circuit to identify exactly where the power loss is occurring—whether it’s a TCO, a switch, or the board itself.

Work Smarter

Accessible Testing Points

You don’t always need to pull the microwave out of the wall. We show you how to perform critical voltage and resistance checks from easily accessible locations like the control panel and door sensing harness.

  • ✓ Testing Door Switches from the Board
  • ✓ Verifying 120V to the Transformer
  • ✓ Identifying Wire Colors on Schematics

The Physics

The High Voltage Circuit

How do we turn 120 Volts into 4,000 Volts? We explain the transformer, capacitor, and diode relationship visually. Once you understand how the energy is stored and rectified, diagnosing a “No Heat” call becomes simple math.

Microwave Training FAQ

Is microwave repair dangerous?
It can be if you don’t know what you are doing. The high-voltage capacitor can hold a lethal charge even when unplugged. This course focuses heavily on safety, teaching you the proper way to discharge the system before you ever touch a component.
Do I need a high voltage probe?
For most diagnostics, no. We teach you how to test the components (Magnetron, Diode, Capacitor) safely using a standard multimeter and resistance checks, rather than measuring live high voltage.
Is this included in the full certification?
Yes! If you purchase the Certified Professional program, the Microwave Specialist module is included at no extra cost. This page is for technicians who only want to add microwave repair to their existing skillset.
