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. Then th

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. 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. (TROUBLE 1) Door shut, timer set,

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. The water is contained in a cylindrical borosilicate glass vessel having a

2. MICROWAVE RADIATION TEST WARNING : Make sure to check the microwave leakage before and after repair of adjustment. Always start measuring of an unknown field to assure safety for operating personnel from microwave energy. Do not place your hands into any suspected microwave radiation field unless the safe density level is known. Care should be taken not to place the eyes in direct line with the source of microwave energy. Slowly approach the unit under test until the radiometer reads an appre
