• 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:
(Put half a cup of water in the oven, on the turntable
and close the door. Select HIGH (100P) and
programme the oven to cook for 1 minute.)

programme the oven to cook for 1 minute.)
1. Does the oven lamp come on when it is cooking?
YES/NO
2. Does the turntable rotate?
YES/NO
3. Does the cooling fan work? (Check by placing
your hand above the air vent openings) YES/NO
4. After 1 minute does the "beep" sound?
YES/NO
5. Is the water in the cup hot?
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 against the
troubleshooting chart on page 20.

• Do not allow grease or dirt to build up
on the door seals and adjacent parts
as this may prevent the door from
closing correctly and may cause a
leakage of microwaves. To clean use
a mild detergent solution on a soft

each use with a mild detergent solution on
a soft cloth, pay special attention to the
waveguide cover.
Take care not to let soapy water drip through the small
holes in the oven walls and the cavity floor particularly
if the turntable and roller stay are removed. Excess
water spillage through these holes will cause damage
to the oven interior. It is important that the door seals
and sealing surfaces are kept clean at all times, wipe
regularly with a damp cloth.
To prevent splashing, cover food wherever possible.
