SERVICE CALL CHECK

Check the following before calling service:
1. Does the display light?
When the door is opened, does the oven lamp light?
If "NO" is the answer for both, check your wall socket and the fuse in your meter box. If both the wall
socket and fuse are functioning properly, CONTACT THE SHARP SERVICE CENTRE.
2. Place one cup of water (approx. 250 ml) in a glass measuring cup in the oven and close the door
securely. Oven lamp should go off if door is closed properly.
Programme the oven for one minute on HIGH. At this moment:
A. Does the oven lamp light?
B. Does the cooling fan work?
(Put your hand over the rear ventilation openings.)
C. Does the turntable rotate?
(The turntable can rotate clockwise or counterclockwise. This is quite normal.)
D. Do the microwave symbol and COOK indicator light?
E. After one minute, did an audible signal sound?
F. Is the water inside the oven hot?
3. Remove water from the oven and programme the oven for 3 minutes on GRILL mode using top and
bottom heaters.
A. Do the top and bottom heater symbols and COOK indicator light? Yes
B. After 3 minutes, do the both heaters become red? (Pay special attention to prevent burns when
checking the bottom heater)
If "NO" is the answer to any of the above questions, please check your wall socket and the fuse in your
meter box.
If both the wall socket and the fuse are functioning properly, CONTACT YOUR NEAREST SERVICE
CENTER APPROVED BY SHARP.
NOTE: 1. If time in the display is counting down rapidly, check Demonstration Mode.
(Please see E-33 for detail.)
2. The following thing is not trouble;
Each cooking mode has a maximum cooking time. If you operate the oven longer than the
