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 100% 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?
Take the cup of water out of the oven and close the 
door.
Programme the oven to cook for 3 minutes using
the convection on 180

°C.

6. After 3 minutes, is the oven cavity 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 on the following
page.

NOTES:
• If you cook for a long time with only the same

cooking mode, the oven will lower the power
automatically to avoid overheating.
Check food is piping hot after cooking. If
necessary, you can extend the cooking time.

• After manual or automatic cooking using the

Speed Grill, Dual Cook or Convection modes,
the cooling fan will switch on to cool the oven
cavity. When the cooling fan works, the display
may show “NOW COOLING”. To clear it, press
the STOP/CLEAR key and the display will return
to the time of day, if set.
During these modes, the cooling fan will carry on
working after you have pressed the
STOP/CLEAR key. You may feel hot air blowing
out of the air-vent openings.

• Your oven has a voltage check function. If the

voltage rises above 10% or falls below 10% of
the required 240 volts, the cooking results would
not be acceptable; therefore the oven will stop,
display an error message and interrupt the
cooking programme. Press the STOP key and
complete the cooking manually. It is imperative
that the power to the oven be checked to ensure
that a 240 volt circuit is serving the oven.

• 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.
