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.

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 microwave 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.

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.

Cooking Mode
Microwave HIGH cooking

Standard Time
20 Minutes
