4. Troubleshooting and Fixes

Now that we’ve identified potential issues let’s roll up our sleeves and dive into practical troubleshooting steps and fixes.

4.1 Testing the Magnetron

To check the magnetron, you’ll need a multimeter. Disconnect the microwave from the power source and follow the manufacturer’s safety guidelines. Measure the continuity; if it’s absent, the magnetron may need replacement.

4.2 Checking the High Voltage Diode

Similar to the magnetron test, use a multimeter to check the continuity of the high voltage diode. A lack of continuity indicates a faulty diode, requiring replacement.

4.3 Inspecting the Thermal Fuse

Inspect the thermal fuse for any signs of damage. If it looks burnt or exhibits no continuity when tested, it’s likely the culprit. Replace the thermal fuse but also investigate what caused it to blow.
