1DCM24BDCM24RDCM24SWARNING TO SERVICE PERSONNELMicrowave ovens contain circuitry capable of pro-ducing very high voltage and current, contact withfollowing parts may result in a severe, possiblyfatal, electrical shock.(Example)High Voltage Capacitor, High Voltage Power Trans-former, Magnetron, High Voltage Rectifier Assem-bly, High Voltage Harness etc..Read the Service Manual carefully and follow allinstructions.Before Servicing1. Disconnect the power supply cord , and thenremove outer case.2. Open the door and block it open.3. Discharge high voltage capacitor.WARNING:RISK OF ELECTRIC SHOCK.DISCHARGE THE HIGH-VOLTAGECAPACITOR BEFORE SERVICING.The high-voltage capacitor remains charged about 60seconds after the oven has been switched off. Wait for 60seconds and then short-circuit the connection of the high-voltage capacitor (that is the connecting lead of the high-voltage rectifier) against the chassis with the use of aninsulated screwdriver.Whenever troubleshooting is performed the power supplymust be disconnected. It may, in some cases, be necessaryto connect the power supply after the outer case has beenremoved, in this event,1. Disconnect the power supply cord, and then removeouter case.2. Open the door and block it open.3. Discharge high voltage capacitor.4. Disconnect the leads to the primary of the powertransformer.5. Ensure that the leads remain isolated from othercomponents and oven chassis by using insulation tape.6. After that procedure, reconnect the power supply cord.When the testing is completed,1. Disconnect the power supply cord, and then removeouter case.2. Open the door and block it open.3. Discharge high voltage capacitor.4. Reconnect the leads to the primary of the powertransformer.5. Reinstall the outer case (cabinet).6. Reconnect the power supply cord after the outer case isinstalled.7. Run the oven and check all functions.After repairing1. Reconnect all leads removed from components duringtesting.2. Reinstall the outer case (cabinet).3. Reconnect the power supply cord after the outer case isinstalled.4. Run the oven and check all functions.Microwave ovens should not be run empty. To test for thepresence of microwave energy within a cavity, place a cupof cold water on the oven turntable, close the door and setthe power to HIGH and set the microwave timer for two (2)minutes. When the two minutes has elapsed (timer at zero)carefully check that the water is now hot. If the waterremains cold carry out Before Servicing procedure and re-examine the connections to the component being tested.When all service work is completed and the oven is fullyassembled, the microwave power output should be checkedand a microwave leakage test should be carried out.Don't Touch !Danger High Voltage
