TROUBLESHOOTING
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, Dual Cooking, Convection, Express Cook
and Auto Cook modes, the cooling fan will switch on
for cooling the oven cavity. When the cooling fan
works, "NOW COOLING" 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.
PROBLEM

POSSIBLE CAUSE/SOLUTION
Check the oven is plugged in.
Plug in another appliance to check the mains supply is feeding the socket.
Replace the fuse.
When the oven is working, air circulates within the cavity. The door does not form an
airtight seal so air may escape from the door.
The oven cavity will normally be colder than the food being cooked, and so steam
produced when cooking will condense on the colder surface. The amount of steam
produced depends on the water content of the food being cooked. Some foods, such
as potatoes have a high moisture content. Condensation trapped in the door glass
should clear after a few hours.
Arcing will occur when a metallic object comes into close proximity to the oven cavity
during cooking. This may remove some of the paint and possibly roughen the surface
of the cavity, but would not otherwise damage the oven. Bare metal should be
touched up with acrylic paint to prevent the formation of rust.
Ensure all "eyes" are removed and stand directly onto the turntable or in a heat
resistant flan dish or similar.
Check the door is closed properly.
Ensure correct mode and power level has been selected.
The cooling fan generates noise.
The microwave energy pulses ON/OFF during cooking/defrosting.
Your oven may be set in demo mode. Follow the steps below to cancel the demo
mode.
1. Press the STOP/CLEAR key for ten seconds until you hear the beep twice.
2. Press the STOP/CLEAR key ten times within ten seconds.
3. The oven display will show "DEMO OFF".
