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.
Simply answer “YES” or “NO” to the following questions:
1.
Does the oven lamp come on when you open the
door?
YES/NO
(Put half a cup of water in the oven, on the turntable
and close the door. 100% and programme the oven to
cook for 1 minute.)
2.
Does the oven lamp come on?
YES/NO
3.
Does the turntable rotate?
YES/NO
4.
Does the cooling fan work? (Check by placing your
hand above the air-vent openings)
YES/NO
5.
After 1 minute does the "beep" sound? YES/NO
6.
Is the water in the cup hot?
YES/NO
(Take the cup out of the oven and close the door. Set the
grill time for the top and bottom grill for 3 minutes.)
7.
At the end of 3 minutes do both the grill elements
become red?
YES/NO
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 the troubleshooting
chart on page 35.
WARNINGS:
• It is hazardous for anyone other than a
competent person to carry out any
service or repair operation which
involves the removal of a cover which
gives protection against exposure to
microwave energy.
• 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 & Modifications: Do not attempt to operate
the oven if it is not working properly.
• Outer Cabinet & Lamp Access: Never remove the
outer cabinet. This would be very dangerous due to
high voltage parts inside which must never be
touched, as this could be fatal. As your oven is not
fitted with a lamp access cover, if the lamp fails, do
not attempt to replace the lamp yourself, call your
dealer or SHARP approved service facility (see page
36).
NOTES:
The following cooking conditions should not cause concern:
1.
If you cook food for more than the standard time (see chart below) at the same power level, the oven’s
safety mechanisms will automatically activate. The microwave power level will be reduced and the grill
heating elements will turn on and off.
2.
After cooking the cooling fan may switch on for cooling the oven cavity. When the cooling fan works,
may be displayed.
During cooking, the cooling fan will also work when you press the
STOP
key. You may feel air blowing
out of the air-vent openings.
