TROUBLESHOOTING
TO REPLACE THE MAINS PLUG
POSSIBLE CAUSE
When oven is working, air circulates within the cavity. The door does not form an
airtight seal, so it is normal for air to 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 stand 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/OFF during cooking/defrosting.
The cabinet may become hot to the touch - keep children away.
Outer cabinet/door is hot.
PROBLEM
Draught circulates around
the door.
Flashing or arcing from
within the cavity when
cooking.
Arcing potatoes.
After setting the time, the
oven does not start.
Oven cooks too slowly.
Oven makes a noise.
Condensation forms in the
oven, and may drip from
the door.
The wires in the mains cable are colour coded as
shown opposite:
As the colours of the cores in the mains lead of your
oven may not correspond with the coloured marking
identifying the terminals in your plug, connect the wires
as shown opposite.
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  230-240 Volt,
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.
