7 1. Steady, flat location This microwave oven should be set on a steady, flat surface. This microwave oven is designed for counter top use only. 2. Leave space behind and side All air vents should be kept a clearance. If all vents are covered during operation, the oven may overheat and, eventually, cause failure.
8 Make sure the oven is properly installed and plugged into the electrical. OPERA TIONS AND FUNCTIONS 1. Connect the main lead to an electrical outlet. 2. After placing the food in a suitable container, open the oven door and put it on the glass tray.
9 DISASSEMBL Y AND ASSEMBL Y Cautions to be observed when troubleshooting. 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.
10 1. T o remove cabinet 1) Remove three screws on cabinet back. 2) Pull the cabinet backward. 2. T o remove door assembly 1) Remove the screw which secure the stopper hinge top. 2) Remove the door assembly from top plate of cavity. 3) Reverse the above for reassembly.
11 3. T o remove door parts. REF NO. PART CODE PART NAME DESCRIPTION Q’TY REMARK A01 3512206440 FRAME DOOR HIPS 1 A02 3517007300 BARRIER-SCREEN*0 PET T0.125 1 A03 3515204100 STOPPER SINGE *T AS KOR-63150S 1 A04 3511719500 DOOR PAINTING AS KOR-6C0B5S 1 A05 3517002800 BARRIER-SCREEN *I T0.

14 6. T o 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.
15 8. T o remove wind guide assembly . 1) Remove a screw for earthing. 2) Remove the noise filter from the wind guide. 3) Remove a screw which secure the wind guide assembly. 4) Draw forward the wind guide assembly. 5) Pull the fan from the motor shaft.
16 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.
17 (TROUBLE 1) Oven does not operate at all ; any inputs can not be accepted. TROUBLESHOOTING 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.
18 CONDITION CHECK Check continuity of primary inter- lock switch Malfunction of pri- mary interlock switch RESULT No Continuity CAUSE REMEDY Adjust or replace Turn table motor and oven lamp do not turn on Check continuity of secondary interlock switch Malfunction of sec- ondary interlock switch No Continuity Adjust or replace Check D.
19 (TROUBLE 3) No microwave oscillation even though fan motor rotates. CONDITION CHECK RESULT Check continuity of high voltage capacitor terminals with wires removed Continuity CAUSE Defective high vo.
20 (TROUBLE 4) The following visual conditions indicate a probable defective touch control circuit or membrane switch assembly. 1 1. Incomplete segments (1) Segments missing (2) Partical segments missing (3) Digit flickering other than normal display slight flickering (4) :0 does not display when power is on.
21 MEASUREMENT AND TEST 1. MEASUREMENT OF THE MICROW A VE 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.
22 2. MICROW A VE RADIA TION TEST PROCEDURES 1 . Prepare Microwave Energy Survey Meter, 600cc glass beaker, and glass thermometer 100 ˚ C(212 ˚ F). 2. Pour 275cc±15cc of tap water initially at 20 ± 5 ˚ C(68±9 ˚ F) in the 600cc glass beaker with an inside diameter of approx.
23 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.
