INSTALLATION 1. Steady, flat location. This microwave oven should be set on a steady, flat surface. 2. Leave space behind and side. All air vents should be kept a clearance. If all vents are covered during operation, the oven may be overheated and, eventually, cause oven failure. 3. Away from radio, and TV sets Poor television reception and radio interference may result if the oven is located close to a TV, radio, antenna, or feeder and so on. 4.
OPERATIONS AND FUNCTIONS 11. Connect the main lead to an electrical outlet. 12. After placing the food in a suitable container, open the oven door and put it on the glass tray. The glass tray must always be in place during cooking. 13. Close the door securely. 14. Choose cooking power level by setting V.P.C knob to the desired position. Refer to cookbook for recommended power levels. 15. Determine cooking time. Consult cookbook for recipe timing. Oven light turns on and cooling fan starts to operate.
DISASSEMBLY AND ASSEMBLY Cautions to be observed when trouble shooting. Unlike many other appliances, the microwave oven is high-voltage, high-current equipment. It is completely safe during normal operation. However, carelessness in servicing the oven can result in an electric shock or possible danger from a short circuit. You are asked to observe the following precautions carefully. 1. Always remove the power plug from the outlet before servicing. 2.
1. To remove cabinet 2. To remove door assembly 1) Remove three screws on cabinet back. 2) Push the cabinet backward. 1) Remove two screws which secure the stopper hinge top. 2) Remove the door assembly from top plate of cavity. 3) Reverse the above for reassembly. 3. To remove door parts. REF NO. PART CODE PART NAME DESCRIPTION A01 3512203880 FRAME DOOR PP SI83C 1 A02 3517007300 BARRIER-SCREEN *O PET T0.

6. To remove high voltage capacitor. 1) Remove a screw which secure the grounding ring terminal of the H.V. diode and the capacitor holder. 2) Remove the H.V. diode from the capacitor holder. 3) Reverse the above steps for reassembly. ◆ High voltage circuit wiring 7. To remove magnetron. 1) Remove a screw which secure the magnetron. 2) Remove the magnetron. 3) Reverse the above steps for reassembly.
8. To remove wind guide assembly. 1) Remove a screw which secure the wind guide assembly. 2) Draw forward the wind guide assembly. 3) Pull the fan from the motor shaft. 4) Remove two screws which secure the motor shaded pole. 5) Remove the motor shaded pole. 6) Reverse the above steps for reassembly. 9. To remove H.V.transformer. 1) Remove four screws holding the H.V.transformer. 2) Remove the H.V.transformer. 3) Reverse the above steps for reassembly.
INTERLOCK MECHANISM AND ADJUSTMENT The door lock mechanism is a device which has been specially designed to completely eliminate microwave radiation when the door is opened during operation, and thus to perfectly prevent the danger resulting from the leakage of microwave. (1) Primary interlock switch When the door is closed, the hook locks the oven door. If the door is not closed properly, the oven will not operate. When the door is closed, the hook pushes the button of the microswitch.
TROUBLE SHOOTING GUIDE Following the procedure below to check if the oven is defective or not. 1. Check grounding before trouble checking. 2. Be careful of the high voltage circuit. 3. Discharge the high voltage capacitor. 4. When checking the continuity of the switches, fuse or high voltage transformer, disconnect one lead wire from these parts and check continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your meter.
Does the fan motor work when you shut the door and turn the timer? YES Does the oven lamp light? NO Does the turntable turn? Replace or repair oven lamp, turntable motor. YES Normal reading should be approx. 0Ω NO If microwave do not oscillate, Continuity check continuity of filament of magnetron. Check continuity filament tap NO Continuity (3.3V) of high voltage. Replace high voltage transformet Poor continuity Continuity Continuity in the reverse Check the diode for continuity direction.
MEASUREMENT AND TEST 1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT Microwave output power can be checked by indirectly measuring the temperature rise of a certain amount of water exposed to the microwave as directed below. PROCEDURE 1. Microwave power output measurement is made with the microwave oven supplied at rated voltage and operated at its maximum microwave power setting with a load of 1000±5cc of potable water. 2.
2. MICROWAVE RADIATION TEST WARNING : 1. Make sure to check the microwave leakage before and after repair of adjustment. 2. Always start measuring of an unknown field to assure safety for operating personnel from microwave energy. 3. Do not place your hands into any suspected microwave radiation field unless the safe density level is known. 4. Care should be taken not to place the eyes in direct line with the source of microwave energy. 5.
3. COMPONENT TEST PROCEDURE • High voltage is present at the high voltage terminal of the high voltage transformer during any cooking cycle. • It is neither necessary nor advisable to attempt measurement of the high voltage. • Before touching any oven components or wiring, always unplug the oven from its power source and discharge the capacitor. 1. High voltage transformer (1) Remove connections from the transformer terminals and check continuity.
