Draught circulates around the door. 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.

Condensation forms in the oven, 
and may drip 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.

Flashing or arcing from within the 
cavity when cooking.

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.

Arcing potatoes.

Ensure all "eyes" are removed from the potatoes and that they have been pierced, place directly onto 
the turntable or in a heat resistant fl an dish or similar.

The display is lit but the control 
panel will not work when pressed.

Check the door is closed properly.

Oven cooks too slowly.

Ensure correct power level has been selected.

Oven makes a noise.

The microwave energy pulses ON and OFF during cooking/defrosting.

Outer cabinet is hot.

The cabinet may become warm to the touch - keep children away.

•  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 Modifi cations: 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 fi tted with a lamp access cover. If the lamp fails, do 
not attempt to replace the lamp yourself, call a SHARP approved 
service facility.

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. 
Programme the oven to cook for 1 minute using 100% microwave 
power.
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 troubleshooting chart below. 

•  The fuse from the cut-off  plug should be removed and the plug 

disposed of in a safe manner.

•  Under no circumstances should the cut-off  plug be inserted into 

a socket outlet as a serious electric shock may occur.

•  The plug must not be used without the fuse cover fi tted.

If you have any doubt about your microwave oven obtain the help 
of a qualified electrician. When replacing the plug please ensure 
that you use a BSI or ASTA approved plug to BS1363, this should be 
fi tted with a brown coloured 13 amp fuse approved by BSI or ASTA 
to BSI 362. If you have any doubt about electrical connection seek 
the help of a qualifi ed electrician.

The wires in the mains cable are colour coded as shown:
Green and yellow stripes  = EARTH 
Blue = 

Brown = 

As the colours in the mains lead of your oven may not correspond 
with the coloured marking identifying the terminals in your plug, 
connect the wires as described:
•  The green and yellow wire to the plug terminal marked E or 

 

or coloured green or coloured green and yellow.

•  The blue wire to the plug terminal marked N or coloured black or 

coloured blue.

•  The brown wire to the plug terminal marked L or coloured red or 

coloured brown.

Make sure the terminal screws are tight and the cable is held 
securely by the cable grip where it enters the plug.
Like most appliances in your home, your oven must be connected to a 
single phase 230-240V~, 50Hz alternating current supply.
If you do not make the proper electrical connections you might 
damage the oven or injure yourself. Neither SHARP nor the supplier 
will be liable if this happens.
