Warning To Service Personnel - Sharp AX-1100R Service Manual

Steam ovens contain circuitry capable of producing very high voltage and current, contact with following parts may result in a severe, pos -
sibly fatal, electrical shock.
(Example)
High Voltage Capacitor, High Voltage Transformer, Magnetron,
High Voltage Rectifier Assembly, High Voltage Harness etc..
Read the Service Manual carefully and follow all instructions.
. Disconnect the power supply cord
2. Open the door and block it open.
3. Discharge high voltage capacitor.
WARNING: RISK OF ELECTRIC SHOCK. DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE SERVICING.
The high-voltage capacitor remains charged about 60 seconds after the oven has been switched off. Wait for 60 seconds 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 an insulated screwdriver.
Whenever troubleshooting is performed the power supply must be disconnected. It may, in some cases, be necessary to connect the pow -
er supply after the outer case has been removed, in this event,
) Disconnect the power supply cord, and then remove outer case.
2) Open the door and block it open.
3) Discharge high voltage capacitor.
4) Disconnect the leads to the primary of the high voltage transformer.
5) Ensure that these leads remain isolated from other components and oven chassis by using insulation tape.
6) After that procedure, reconnect the power supply cord.
. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Reconnect the leads to the primary of the high voltage transformer.
5. Reinstall the outer case (cabinet).
6. Reconnect the power supply cord after the outer case is installed.
7. Run the oven and check all functions.
. Reconnect all leads removed from components during testing.
2. Reinstall the outer case (cabinet).
3. Reconnect the power supply cord after the outer case is installed.
4. Run the oven and check all functions.
Steam ovens should not be run empty. To test for the presence of microwave energy within a cavity, place a cup of cold water on the oven
turntable, close the door and set the power to HIGH (00%) 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 water remains 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 fully assembled, the microwave power output should be checked and microwave leak -
age test should be carried out.
