CHAPTER 2. 
WARNING TO SERVICE PERSONNEL
Microwave ovens contain circuitry capable of producing very high voltage and current, contact with any part of the high voltage circuit will result in
electrocution. High voltage capacitor, Power transformer, Magnetron, High voltage rectifier assembly, High voltage fuse, High voltage harness.
REMEMBER TO CHECK 3D
1) Disconnect the supply.
2) Door opened, and wedged open.
3) Discharge the high voltage capacitor.
WARNING: AGAINST THE CHARGE OF THE HIGH-VOLTAGE
CAPACITOR
The high-voltage capacitor remains charged about 60 sec-
onds after the oven has been switched off. Wait for 60 sec-
onds and then short-circuit the connection of the high-
voltage capacitor (that is, of the connecting lead of the
high-voltage rectifier) against the chassis with the use of
an insulated screwdriver. 
Sharp recommend that wherever possible fault-finding is carried out
with the supply disconnected. It may, in some cases, be necessary to
connect the supply after the outer case has been removed, in this
event carry out 3D checks and then disconnect the leads to the pri-
mary of the power transformer. Ensure that these leads remain iso-
lated from other components and the oven chassis. (Use insulation
tape if necessary.) When the testing is completed, carry out 3D checks
and reconnect the leads to the primary of the power transformer.
REMEMBER TO CHECK 4R
1) Reconnect all leads removed from components during testing.
2) Replace the outer case (cabinet).
3) Reconnect the supply.
4) Run the oven. Check all functions.
Microwave 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 level to HIGH
(100%). 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 3D checks 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 leakage test
should be carried out.
Before replacing the Printed Wiring Board
Some normal boards are found in board units that have been returned due to oven failure. So, most of board replacements may arise from poor har-
ness connection. Accordingly, before replacing any board that was judged to require its replacement, use the following procedure to re-check that the
connection terminal of a connector has been properly inserted:
1.
When the connectors have been incorrectly inserted to the control unit.
2.
When latch switch adjustment is incorrect
When latch switch adjustment is incorrect, symptoms such as no heating, no heating start, no activation even with start button pressed, etc. will
occur.
3. Final error code is memorized in ROM (control unit). (Refer to Error list EE code on page 10-1.)
4. When the intake damper motor is locked or wire leads to it are not connected, cooking mode is stopped 1minute after starting cooking.
5. 3minutes after stopping cooking, energy save mode will work and no segment is displayed.

ment do not operate
