25. 24. Microwave Oven Use and Care Guide
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.”
Questions and Answers (Cont.) Cleaning and Care
of the Microwave Oven (Cont.)
Surface Cleaning Surface
Wave Guide The wave-guide cover is a light brown mica panel
Cover located on the right side of the oven interior. Carefully
clean with mild soap and water. Rinse and dry with a soft
cloth. Do not use any type of abrasive cleaner. Do not
remove the wave-guide cover.
Vents To maintain efficient cooling and ventilation do not allow
dust to accumulate on the vents and air intake (located on
the rear of the oven). To keep them clean use a sponge
dampened with warm soapy water to clear away.
Question
Why is the Microwave Oven
light not on during cooking?
Why does steam come out of
the air exhaust vent?
Will the microwave be
damaged if it operates empty?
Does Microwave energy pass
through the viewing screen in
the door?
Answer
• There may be several reasons why
the Microwave Oven light is not on.
• Have you: Set a cooking time?
Pressed “START”?
• The Oven Light needs replacing.
• Steam is normally produced during
cooking. The Microwave Oven has
been designed to vent this steam.
• Yes. Never operate the Microwave
Oven empty or without the glass
turntable.
• No. The metal screen bounces the
energy back to the Microwave Oven
cavity. The holes (or ports) allow only
light to pass though. They do not let
microwave energy pass though.
