INTERLOCK MECHANISM AND ADJUSTMENT(ELECTRICAL) 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 shooting. 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 tranformer, disconnect one load 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.
CONDITION Outlet has proper voltage Fuse does not blow. CHECK RESULT CAUSE REMEDY No Continuity Defective magnetron Replace Check continuity of magnetron Check continuity of power supply cord No Continuity Open power supply cord Replace Normal Defective touch control circuit Replace Malfunction of secondary interlock switch Replace Display do not shown countdown NOTE 1 All these switches must be replaced at the same time, please refer to “Interlock Mechanism And Adjustment”.

MEASUREMENT AND TEST 1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT Microwave output power can be checked by indirectly mmeasuring 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 100 ± 5cc of potable water. 2.
2. MICROWAVE RADIATION TEST CAUTION 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. 2) Normal readings should be as follows : Secondary winding .
