Question
Why does a tone sound when a
button on the control panel is
pressed?
Can my Microwave Oven be
damaged if food is cooked for
too long?
When the Microwave Oven is
plugged into the wall outlet for
the first time it might not work
properly. What is wrong?
Why do I see reflection around
the outlet case?
What are the various sounds
I hear when the Microwave
Oven is operating?
Answer
• The tone tells you that the setting
has been entered.
• Like any other cooking appliance, it
is possible to overcook food to the
point that the food creates smoke
and even possibly fire, resulting in
damage to the inside of the
Microwave Oven. It is always best to
be near the Microwave Oven while
you are cooking.
• The microcomputer controlling
your Microwave 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
Microwave Oven from the 120 volt
household outlet and then plug it
back in to reset the microcomputer.
• The light is from the Microwave
Oven light which is located between
the Microwave Oven cavity and the
outer wall of the Microwave Oven.
• 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 voltage caused by the magnetron
being turned “ON” and “OFF.”
