• The door seal stops microwave leakage during

oven operation, but does not form an airtight seal. It
is normal to see drops of water, light or feel warm
air around the oven door. Food with a high
moisture content will release steam and cause
condensation inside the door which may drip from
the oven.

• Repairs & Modifications: Do not attempt to

operate the oven if it is not working properly. 

• Outer Cabinet & Lamp Access:  Never remove the

outer cabinet. This would be very dangerous due
to high voltage parts inside which must never be
touched, as this could be fatal. As your oven is not
fitted with a lamp access cover, if the lamp fails,
do not attempt to replace the lamp yourself, call a
Service Technician appointed by SHARP. 

If you think the oven is not working properly there are
some simple checks you can carry out yourself before
calling an engineer. This will help prevent unnecessary
service calls if the fault is something simple.
Simply answer “YES” or “NO” to the following questions:

1. Does the oven lamp come on when you 

open the door? 

YES/NO

(Put half a cup of water in the oven, on the 
turntable and close the door. Select 100% HIGH 

and programme the oven to cook for 1 minute.)

2. Does the oven lamp come on?

YES/NO

3. Does the turntable rotate?

YES/NO

4. Does the cooling fan work? (Check by placing

your hand above the air-vent openings) YES/NO

5. After 1 minute does the "beep" sound? YES/NO
6. Is the water in the cup hot?

YES/NO

7. Set the grilling time for the upper and lower grill

for 3 minutes. At the end of 3 minutes do both the
grill elements become red?

YES/NO

If you answer “NO” to any question first check that the
oven is plugged in properly and the fuse has not
blown, if there is no fault with either, check the
troubleshooting chart on page 60.

NOTES:
The following cooking conditions should not cause concern:
1. If you cook food for more than the standard time 

(see chart opposite) at the same power level, the
oven’s safety mechanisms will automatically activate.
The microwave power level will be reduced and the
grill heating elements will turn on and off.

2. After Grill, Dual Grill, Pizza, Breakfast, Instant Cook

and Auto Cook modes, the cooling fan will switch on
for at least 5 minutes.

3. During Grill, Dual Grill, Pizza, Breakfast, Instant Cook

and Auto Cook modes, the cooling fan will also work
when you press STOP/CLEAR. You may feel air
blowing out of the air-vent openings.
After operation of the cooling fan, the display will
show “0.”, if the clock is not set. If the clock is set, it
will show the time of day.
To clear it, press the STOP/CLEAR key and the
display will show the time of day, if set.

close the oven door. See page 7.
