– 34 –Capacitor and DiodeThe capacitor has an internal shunt resistor toautomatically discharge the capacitor when themicrowave oven turns off. Under normal operation,the capacitor should fully discharge within 30seconds.WARNING: Always be certain the capacitor isdischarged before servicing. Mechanically dischargethe capacitor by placing an insulated-handlescrewdriver between the diode connection on thecapacitor and the oven chassis ground.Note: Use the screw head closest to the capacitor toensure ground metal contact.To remove the capacitor and diode:1. Remove the outer cover. (See Outer Cover.)2. Disconnect the wiring to the high voltagecapacitor.3. Remove the Phillips-head screw that attachesthe capacitor and diode to the oven and removethe high voltage capacitor.4. Disconnect the diode from the high voltagecapacitor.DiodeDisconnectDisconnect9. Grasp the hub of the cooling fan blade and pullthe cooling fan blade off the motor shaft.10. Remove 2 Phillips-head screws that attach thecooling fan motor to the cooling fan frame.8. Move the cooling fan frame out thru the rightside of the microwave oven.
