Page 13: The Heating Principle Of Microwave
THE HEATING PRINCIPLE OF MICROWAVE Microwave is one kind of radio wave whose wave length is very short, frequency is very high. Therefore, it is called ultrahigh frequency electromagnetic wave. Microwave can heat food mainly result in the mutual affect of the food in the microwave field and microwave field itself. -

Page 20: Trouble Shooting Procedures
TROUBLE SHOOTING PROCEDURES Before overhauling a microwave oven, you should judge the breakdown and the cause correctly, then you can repair it with corresponding ways. The overhauling must be proceed in order, any hasty conclusion is not recommendable, otherwise overworking would be done when repair. The microwave oven may occur compound breakdown due to all kinds of different reasons, thus, when overhaul, they all should be taken into consideration. - Page 21 Examine when the oven at operating, but the food can’t be heated Pull out the power plug, take off the outer case, discharge the capacitor, measure the resistance value of the primary winding and the secondary winding of the transformer with a multi meter (FIG.5-3 and FIG.5-4). The resistance value of the primary winding should be about 2.2 ohm, the secondary winding should be about 130 ohm, otherwise, it indicates the transformer has broken, and should be replaced by a new one.
- Page 22 FIG5.10 FIG.5-9 Ⅲ.REPAIRING METHOD OF SEVERAL BREAKDOWN Repair when there occurred large amounts microwave leakage. There are many factors, which may cause microwave leaking. Following mentioned may be the main cause of microwave leakage: (1) The door deformed, the hinge loosed or damaged that caused the door can not close tightly. (2) The door pressing cover or the embed piece damaged or come off.
- Page 23 Means of repair when the oven can heat, but the turntable glass can’t move Firstly, check whether the turntable holder is placed correctly. If it is correct, then pull out the power plug and take down the turntable combination, measure the resistance value of the turntable motor with Rx1k grade of a multi meter If it is open- circuited, it indicates the turntable motor has broken, and should be replaced by a new, same model one.

IMPORTANT THINGS TO DO PRIOR TO CRITICAL PART SERVICING The following instructions are CRITICAL to the owner’s safety. Be sure to follow all the instructions. Contact the manufacturer of distributor if you have any question. If the oven is operative prior to servicing a Microwave Leakage Test (Microwave Emission Check) should be performed prior to servicing the oven. -
Page 27: Safety Checks And Tests After Serving
SAFETY CHECKS AND TESTS AFTER SERVING Constructional Checks If mechanical or electrical(electronic) parts have been replaced be sure to follow the following steps. Check for correct wiring, adequate mechanical decrements of parts, and firm connectors. Check for adequate grounding. Check the following items before turning the oven ON. Proper door closing, seal/choke surfaces, and hinges.
