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.

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.

•  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.

IMPORTANT:
If the display is blank and has gone dark, even if
the power plug is properly connected, the oven
may be in Energy Save Mode. To cancel it, open
and then close the oven door, see page 7.

Microwave HIGH cooking

20 Minutes

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 and the potatoes have been pierced, place 
directly onto the turntable or in a heat resistant flan 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.
