Microwave oven repairs usually must pay attention to security issues below.DDNservice manual download site

    First, before disassemble repair must first safety-related parts and components for inspection , mainly to see whether the door is closed, the door gap is too large, the observation window is broken , and the outer casing of the oven cavity there are no joints sealing off the door gasket is defect and uneven and so on. This is to check whether a possible excessive leakage of microwave . If you find a problem , you should first repair ; Ruoyin missing parts or for other reasons can not be repaired temporarily , can the other pre machine failures, but do not force the use of other faults repaired , but can not be delivered to users, be sure to completely rule out the security risks after before delivery.DDNservice manual download site

    Second, if you need to check the machine inside the circuit , usually in power after the microwave oven should be demolished . After disassemble , first with plastic insulated handle screwdriver to short-circuit high voltage across the capacitor discharges from accidental electrical shock when servicing . This is because the microwave power, high voltage capacitors may still exist on a higher voltage , especially near the stove off even more , do not think power after secure.DDNservice manual download site

    Third, in addition to measuring 220v mains voltage checks, in the absence of very grasp, should try to live without power check . If you really need to check energized , you must first disconnect the high voltage circuit , not magnetron , and then start checking to ensure personal safety. As for checking the magnetron and power supply circuit , unless you have the necessary professional knowledge and experience in maintenance of equipment , or should be checked using the power way to ensure safety. Practice shows that as long as the relevant skills to master the essentials , power check does not much worse than the power- examination to determine the speed or even better than some of the fault current testing .
