4. Disassembly and Reassembly 4-1 Replacement of Magnetron, Motor Assembly and Lamp Remove the magnetron including the shield case, permanent magnet, choke coils and capacitors (all of which are contained in one assembly). 1. Disconnect all lead wires from the magnetron and lamp. 2. Remove the bracket mounting. 3. Remove the magnetron supporter. 4. Remove the air cover. 5. Remove screws securing the magnetron to the wave guide. 6. Take out the magnetron very carefully. 7. Remove screws from the back panel.
4-3 Replacement of Door Assembly 4-3-1 Removal of Door Assembly Remove hex bolts securing the upper hinge and lower hinge. Then remove the door assembly. 4-3-2 Removal of Door "C" Insert flat screwdriver into the gap between Door "E" and Door "C" to remove Door "C". Be careful when handling Door "C" because it is fragile. 4-3-3 Removal of Door "E" Door "E" Following the procedure as shown in the figure, insert and bend a thin metal plate between Door "E" and Door "A" until you hear the 'tick' sound. 1.
4-3-5 Reassembly Test After replacement of defective component parts of the door, reassemble it and follow the instructions below for proper installation and adjustment so as to prevent an excessive microwave leakage. 1. When mounting the door to the oven, be sure to adjust the door parallel to the bottom line of the oven face plate by moving the upper hinge and lower hinge in the direction necessary for proper alignment. 2.
4-6 Replacement of Control Circuit Board 4-6-1 Removal of Control Box Assembly 1. Be sure to ground any static electric charge in your body and never touch the control circuit. 2. Disconnect the connectors from the control circuit board. 3. Remove screws securing the control box assembly. 4. Remove the screw securing the ground tail of the keyboard. Control Box Screw 4-6-2 Removal of Ass'y P.C.B Assembly 1. Remove screws securing the control circuit board. 2.
5. Alignment and Adjustments PRECAUTION 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. 5-1 High Voltage Transformer 1. Remove connectors from the transformer terminals and check continuity. 2. Normal resistance readings are as follows: Secondary Approx.
5-4 High Voltage Capacitor 1. 2. 3. 4. 5. 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 9Mഐ. A shorted capacitor will show continuous continuity. An open capacitor will show constant 9Mഐ. Resistance between each terminal and chassis should read infinite. 5-5 High Voltage Diode 1. Isolate the diode from the circuit by disconnecting its leads. 2.
5-8 Output Power of Magnetron CAUTION 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 : * Two 1-liter cylindrical borosilicate glass vessel (Outside diameter 190 mm) * One glass thermometer with mercury column NOTE: Check line voltage under load. Low voltage will lower the magnetron output.
5-9 Procedure for Measurement of Microwave Energy Leakage 1) 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. 2) Start to operate the oven and measure the leakage by using a microwave energy survey meter. 3) Set survey meter with dual ranges to 2,450MHz. 4) When measuring the leakage, always use the 2 inch spacer cone with the probe. Hold the probe perpendicular to the cabinet door.
6. Troubleshooting PRECAUTION 1. 2. 3. 4. CHECK GROUNDING BEFORE CHECKING FOR TROUBLE. BE CAREFUL OF THE HIGH VOLTAGE CIRCUIT. DISCHARGE THE HIGH VOLTAGE CAPACITOR. WHEN CHECKING THE CONTINUITY OF THE SWITCHES OR TRANSFORMER, DISCONNECT ONE LEAD WIRE FROM THESE PARTS AND THEN CHECK CONTINUITY WITHOUT THE POWER SOURCE ON. TO DO OTHERWISE MAY RESULT IN A FALSE READING OR DAMAGE TO YOUR METER. 5. DO NOT TOUCH ANY PART OF THE CIRCUIT OR THE CONTROL CIRCUIT BOARD, SINCE STATIC DISCHARGE MAY DAMAGE IT.
6-1 Electrical Malfunction(continued) SYMPTOM CAUSE Oven lamp and fan motor turn on 1. Misadjustment or loose wiring of primary latch switch 2. Defective primary latch switch Oven can program but timer does not start. 1. Open or loose wiring of secondary interlock switch 2. Off-alignment of primary interlock 3. Defective secondary interlock S/W Microwave output is low;. Oven takes longer time to cook food. 1. Decrease in power source voltage. 2. Open or loose wiring of magnetron filament circuit.
