TROUBLESHOOTING
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
100P 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.
NOTE:
If you cook food for more than the standard time
(see chart opposite) 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.
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 from the potatoes and that they 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.
