QUESTIONS AND ANSWERS
Q.
When the microwave oven is plugged into a wall outlet for the first
time, it does not work properly. What is wrong?
A.
The microcomputer used in the microwave oven control may
temporarily become scrambled and fail to function as programmed.
Unplug the oven from the wall outlet and then plug it back in again. The
microcomputer should then automatically reset for proper functioning.
Q.
Why is there noise coming from the turntable when the microwave
oven is turned on?
A.
This noise occurs when the turntable roller rest and cavity bottom are
dirty. Clean the turntable roller rest and cavity bottom. Frequent
cleaning of these parts should eliminate or reduce the noise.
Q.
Why is there noise coming from the microwave oven when reducing
power?
A.
When cooking with a power other than P100, the oven cycles on and off
to obtain the lower power level. The clicking noise can be heard when
the oven cycles on and off. This is normal.
Q.
Why is there steam coming out of the air exhaust vent?
A.
Steam is produced during cooking. The microwave oven has been
made to vent this steam out of the air exhaust vent.
Q.
What is wrong when the microwave oven interior light will not glow?
A.
There may be several reasons why the interior light will not glow. The
light bulb may have burned out or
START
may not have been pressed.
Replace the light bulb or press
START
. Never replace the light bulb by
yourself. Contact an Authorized Service Center.
Q.
Why do eggs sometimes pop?
A.
The egg yolk may pop because of steam build-up inside the membrane.
Pierce the membrane with a toothpick before cooking it.
Never
microwave eggs in the shell since they may explode.
Q.
How are boil-overs avoided?
A.
Use a larger utensil than usual for cooking or use a lower power level.
If you open the microwave oven door or touch
STOP/CLEAR
, the food
will stop boiling.
Q.
Why does the beep tone sound when a pad on the control panel is
pressed?
A.
The beep tone sounds to assure that the setting is being properly
entered. However, you can turn off the beep tone. See optional settings
on page 18.
