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.

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. Select HIGH (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

(Programme the oven on convection 180°C for 3

minutes.)

 

8.

Does the oven lamp come on?

YES/NO

9.

Does the turntable rotate?

YES/NO

10.After 3 minutes is the oven cavity hot? 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 62.

NOTES:

The following cooking conditions should not cause concern:

1.If you cook food for more than the standard time (see chart opposite) 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 Grill (using both grill heaters), Dual Cooking, Convection, Pizza, Breakfast, Instant Cook and Auto

Cook modes, the cooling fan will switch on for cooling the oven cavity. When the cooling fan works, will be displayed.

During these modes, the cooling fan will also work when you press STOP/CLEAR. You may feel air blowing out of the air-vent openings.

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 a Service Technician appointed by SHARP.
