Troubleshooting, To Replace the Mains Plug

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 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?

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.

TROUBLESHOOTING CHART

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.

TO REPLACE THE MAINS PLUG

The wires in the mains cable are colour coded as shown:

Green and yellow stripes	= EARTH
Blue	= NEUTRAL
Brown	= LIVE

As the colours in the mains lead of your oven may not correspond with the coloured marking identifying the terminals in your plug, connect the wires as described:

•The green and yellow wire to the plug terminal marked E or or coloured green or coloured green and yellow.

•The blue wire to the plug terminal marked N or coloured black or coloured blue.

•The brown wire to the plug terminal marked L or coloured red or coloured brown.

Make sure the terminal screws are tight and the cable is held securely by the cable grip where it enters the plug.

Like most appliances in your home, your oven must be connected to a single phase 230-240V~, 50Hz alternating current supply.

If you do not make the proper electrical connections you might damage the oven or injure yourself. Neither SHARP nor the supplier will be liable if this happens.

•The plug must not be used without the fuse cover fitted.

If you have any doubt about your microwave oven obtain the help of a qualified electrician. When replacing the plug please ensure that you use a BSI or ASTA approved plug to BS1363, this should be fitted with a brown coloured 13 amp fuse approved by BSI or ASTA to BSI 362.
