Question Answer
Why is the oven light not
on during cooking?
There may be several reasons why the oven light is not on.
Have you:
•Set a cooking time?
•Touched START?
Why does steam come
out of the air exhaust
vent?
Steam is normally produced during cooking. The microwave
oven has been designed to vent this steam.
Will the microwave oven
be damaged if it
operates empty?
Yes. Never operate the oven empty or without the glass
turntable.
Does microwave energy
pass through the viewing
screen in the door?
No. The metal screen bounces the energy back to the oven
cavity. The holes (or ports) allow only light to pass though. They
do not let microwave energy pass though.
Why does a tone sound
when a pad on the
control panel is
touched?
The tone tells you that the setting has been entered.
Can my microwave oven
be damaged if food is
cooked for too long?
Like any other cooking appliance, it is possible to overcook food
to the point that the food creates smoke and even possibly fire,
and damage to the inside of the oven. It is always best to be
near the oven while you are cooking.
When the oven is
plugged into wall outlet
for the first time, it might
not work properly. What
is wrong?
The microcomputer controlling your oven may temporarily
become scrambled and fail to function as programmed when
you plug in for the first time or when power resumes after a
power interruption. Unplug the oven from the 120 volt household
outlet and then plug it back in to reset the microcomputer.
Why do I see reflection
around the outlet case?
The light is from the oven light which is located between the
oven cavity and the outer wall of the oven.
What are the various
sounds I hear when the
microwave oven is
operating?
The clicking sound is caused by a mechanical switch turning the
microwave oven’s magnetron ON and OFF.
The heavy hum and clunk is from the change in power the
magnetron draws as it is turned ON and OFF by a mechanical
switch. The change in blower speed is from the change in line
