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.
Follow this simple check below:
Place half a cup of water on the turntable and
close the door. Select HIGH and programme the
oven to cook for 1 minute.
1. Does the oven lamp come on when it is cooking?
2. Does the turntable rotate?
3. Does the cooling fan work? (Check by placing
your hand above the air vent openings.)
4. After 1 minute does the audible signal sound?
5. Is the water in the cup hot?
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 chart below.
• 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 and Modifications: Do not attempt to
operate the oven if it is not working properly.
• Outer Cabinet & Lamp Access: Never remove
the outer cabinet. This is very dangerous due
to high voltage parts inside which must never
be touched, as this could be fatal.
Your oven is not fitted with a lamp access
cover. If the lamp fails, do not attempt to
replace the lamp yourself, call a SHARP
approved service facility.
TROUBLESHOOTING
WARNING:
Never adjust, repair or modify the oven
yourself. It is hazardous for anyone other
than a SHARP trained engineer to carry
out servicing or repairs.
This is important as it may involve
the removal of covers that provide
protection against microwave energy.
ANSWER
When the oven is working, air circulates within the cavity.
The door does not form an airtight seal so air may escape from the door.
The oven cavity will normally be colder than the food being cooked, and so
steam produced when cooking will condense on the colder surface.
The amount of steam produced depends on the water content of the food
being cooked. Some foods, such as potatoes have a high moisture content.
Condensation trapped in the door glass should clear after a few hours.
Arcing will occur when a metallic object comes into close proximity to
the oven cavity during cooking. This may possibly roughen the surface of
the cavity, but would not otherwise damage the oven.
Ensure all “eyes” are removed and the potatoes have been pierced, place
directly onto the turntable or in a heat resistant flan dish or similar.
Check the door is closed properly.
Ensure correct power level has been selected.
The micro
wave energy pulses ON and OFF during cooking/defrosting.
The cabinet may become warm to the touch - keep children away.
QUERY
Draught circulates
around the door.
Condensation forms in
the oven, and may drip
from the door.
Flashing or arcing from
within the cavity when
cooking.
Arcing potatoes.
The display is lit but the
control panel will not
work when pressed.
Oven cooks too slowly.
Oven makes a noise.
Outer cabinet is hot.
NOTE:
If you cook food for more than the standard time
(see chart below) using the same cooking mode, the
oven’s safety mechanisms automatically activate. The
microwave power level will be reduced.
