    1. The digital programmer circuit determines the power level and cooking time to complete cooking and indicates the operating state in the display window. / Table shows the corresponding cooking times for respective serving or weight by categories. 2. When cooking time in the display window has elapsed, the oven turns off automatically by a control signal from the digital programmer circuit.
  • Page 13 WARNING There is high-voltage present, with high-current capabilities in the circuits of the high voltage winding and filament winding of the high voltage transformer. It is extremely dangerous to work on or near these circuits with oven energized. / DO NOT measure the voltage in the high voltage circuit including filament voltage of magnetron.

    3. When replacing faulty switches, be sure mounting tabs are not bent, broken or otherwise deficient in their ability to hold the switches. 6.5. Avoid inserting nails, wire, etc. through any holes in the unit during operation. Never insert a wire, nail or any other metal object through the lamp holes on the cavity or any other holes or gaps, because such objects may work as an antenna and cause microwave leakage.

    PROCEDURE 7.1. Magnetron 1. Discharge the high voltage capacitor. 2. Remove 1 screw holding air guide A & reinforce bracket. 3. Disconnect 2 high voltage lead wires from magnetron filament terminals. 4. Remove 4 screws holding the magnetron. NOTE: After replacement of the magnetron,tighten mounting screws properly in an X pattern, making sure there is no gap between the waveguide and the magnetron to prevent microwave leakage.

    3. Remove the turntable motor by removing 1 screw. NOTE: After reinstalling the new turntable motor and reconnecting the 2 lead wires, reinstall the motor cover by rotating it around 180°, tucking the 2 tabs under the base into the 2 provided slots, then screw the single tab to the base using a screw.
  • Page 21 2. Unplug lead connectors to primary Latch switch and Door Switch. 3. Test the continuity of switches at door opened and closed positions with ohm meter (low scale). / Normal continuity readings should be as follows. 8.2. Short Switch & Monitor 1.
  • Page 22 2. A normal capacitor will show continuity for a short time, and then indicate 9M once the capacitor is charged. 3. A shorted capacitor will show continuous continuity. 4. An open capacitor will show constant 9M . 5. Resistance between each terminal and chassis should be infinite. 8.5.
  • Page 23 1. Select any power other than “High“ and start the oven. 2. Check continuity between both terminals of the variable power switch. 3. Variable power controller (timer and variable power switch) is working proporty it the ohm meter reads open and 0 within 30 ± 2 seconds interval as shown in table on P.9.
