1. Precaution Follow these special safety precautions. Although the microwave oven is completely safe during ordinary use, repair work can be extremely hazardous due to possible exposure to microwave radiation, as well as potentially lethal high voltages and currents. 1-1 Safety precautions ( All repairs should be done in accordance with the 13.
1. Precaution 1-2 Special High Voltage Precautions High Voltage Warning Do not attempt to measure any of the high voltages --this includes the filament voltage H. V. Capacitor of the magnetron. High voltage is present during any cook cycle. Before touching any components or wiring, always unplug the oven and discharge the high voltage capacitor (See Figure 1-1) The high-voltage capacitor remains charged about...

Disassembly and Reassembly 4-6 Replacement of Control Circuit Board Be sure to dislyarge any static electricity from your body, and avoid touching the “touch control” circuitry Disconnect the connectors from the control circuit board. Remove screws securing the control box assembly. Lift up the control circuit board from right side and remove the hooks holding the control circuit board to box assembly SCREWS...
5. Alignment and Adjustments 1. High voltage is present at the high voltage terminals during any cook cycle. 2. It is neither necessary nor advisable to attempt measurement of the high voltage. 3. Before touching any oven components or wiring, always unplug the oven from its power source and discharge the high voltage capacitor.
5. Alignment and Adjustments 5-4 High Voltage Capacitor Check continuity of the capacitor with the meter set at the highest resistance scale. Once the capacitor is charged, a normal capacitor shows continuity for a short time, and then indicates 9MΩ. A shorted capacitor will show continuous continuity.
5. Alignment and Adjustments 5-8 Output Power of Magnetron MICROWAVE RADIATION PERSONNEL SHOULD NOT ALLOW EXPOSURE TO MICROWAVE RADIATION FROM MICROWAVE GENERATOR OR OTHER PARTS CONDUCTING MICROWAVE ENERGY. The output power of the magnetron can be measured by performing a water temperature rise test. Equipment needed : •...
5. Alignment and Adjustments 5-9 Procedure for Measurement of Microwave Energy Leakage Pour 275±15cc of 20±5°C(68±9°F) water in a beaker which is graduated to 600cc, and place the beaker in the center of the oven. Start to operate the oven and measure the leakage by using a microwave energy survey meter.
