TROUBLESHOOTING

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. Select HIGH and programme the oven to cook for 1 minute.

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 chart below.

NOTE:

If you cook food for more than the standard time (see chart below) using the same cooking mode, the oven’s safety mechanisms automatically activate. The microwave power level will be reduced.

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.

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.
