Questions and answers
A: When the oven does not turn on, check the following:
1. Is the oven plugged in securely? Remove the plug from the outlet, wait 10 seconds
and reinsert.
2. Check the circuit breaker and the fuse. Reset the circuit breaker or replace the fuse if it
is tripped or blown.
3. If the circuit breaker or fuse is all right, plug another appliance into the outlet. If the
other appliance works, there probably is a problem with the oven. If the other appliance
does not work, there probably is a problem with the outlet.
If it seems that there is a problem with the oven, contact an authorized Service Centre.
A: Some radio and TV interference might occur when you cook with the microwave oven.
This interference is similar to the interference caused by small appliances such as mixers,
vacuums, blow dryers, etc. It does not indicate a problem with your oven.
A: The oven is designed not to accept an incorrect program. For example, the oven will not
accept a fourth stage, and will not accept an Auto Weight Program after Delay Start.
A: The heat given off from the cooking food warms the air in the oven cavity. This warmed air
is carried out of the oven by the air flow pattern in the oven. There are no microwaves in the
air. The oven vents should never be blocked during cooking.
A: The oven has programmed DEMO MODE. This mode is designed for retail store display.
Deactivate this mode by pressing Microwave Power once and Stop/Cancel Pad 4 times
(NN-GD560M / NN-GD550W) or Max Microwave Power Pad once and Stop/Cancel Pad 4
times (NN-SD450W).
A: Only when you are using GRILL cooking mode
some thermometers may cause arcing in your oven and should not be used on
MICROWAVE and COMBINATION cooking modes.
A: The display indicates a problem with the microwave generation system. Please
contact an authorised Service Center.
A : There may have been a power failure, and the wordprompt is disabled. Unplug the oven for
a few seconds, then plug it again. When "88:88" is displayed, press the start pad until your
language is displayed. Then set the clock. Refer to page En-7.
A: The noises occur as the oven automatically switches from MICROWAVE power to GRILL to
create the combination setting. This is normal.
A: After repeated use, it is recommended to clean the oven and then run the oven without
food, glass tray, and roller ring on Grill for 5 minutes. This will burn off any food, residue or
oil which may cause an odour and/or smoking.
