Display
Cause
O
Displays when the oven has been used for 17,500 hours.
Please contact the dealer or a service agent to replace the
parts.
O
Displays when the magnetron has been used 120,000 times.
Please contact the dealer or a service agent to replace the
parts.
O
The above time and number of operations is not a guarantee.
Troubleshooting
Troubleshoot following the next procedure when there is a problem.
Symptom
Cause
It does not operate at all
O
Is there a power outage?
O
Is the breaker in the power distribution board tripped, or the
power supply plug unplugged?
O
Is the initial screen displayed in the control panel? If the auto
power OFF function is in operation, perform the operation after
the initial screen is displayed by opening the door.
It does not cook correctly
O
Is the cook setting, accessory, or the cook time incorrect?
O
Has the oven been sufficiently preheated?
There is a sound
O
There will be a sound of cooking starting, and the fan will sound.
There is smoke or harsh odor
O
A smoke or harsh odor may occur due to burning of the oil for
oven cavity protection when the heater is turned on for the first
time. Always ventilate and perform a blank baking if it concerns
you. (p.6)
There are sparks during
cooking
O
A metal container can only be used in the oven when not using
microwave power. (p.11)
O
Is a container containing gold or silver particles used?
O
Is any metal (aluminium foil, metallic skewer, etc.) touching the
wall of the oven cavity?
O
Is the oven cavity rusted? Rust may cause sparks.
The buzzer does not beep
O
Is the loudness of the beep set to OFF?
The buzzer will not beep when it is set to OFF. (p.24)
There is an odor or smoke
O
This is not a malfunction. The catalyst reaction will lower when
the cooking temperature is low (approximately 475°F (250°C) or
lower). Also, it may exceed the processing ability when the
amount of oil smoke generated during cooking is high.
There is a sour odor
O
Depending on the food, a sour odor may occur during cooking,
but this is caused by the catalyst reaction and it is not abnormal.
Foods “explode” during
heating
O
Microwave power level is too high.
Reduce power level.
O
Skins of foods i.e potatoes, chicken are not pierced.
Pierce skins on foods to release pressure build up during
heating. NEVER try to boil eggs in shells.
Smoke appears around the
door when broiling
O
Fat from food is splashing on to the broil elements and burning.
Stop the oven and drain away all excess fat and juices. Watch
the food carefully as it broils. Ensure the cavity ceiling and all
accessories are cleaned regularly.
