When the oven is plugged into the wall
outlet for the first time, it doesn't work
properly. What is wrong?
Steam is normally produced during cooking. The microwave oven
has been designed to vent this steam.
Yes. Never operate the oven empty or without the glass turntable.
No. The metal screen bounces the energy back to the oven cavity.
The holes (or ports) allow only light to pass through. They do not
let microwave energy pass through.
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
and damage to the inside of the oven. It is always best to be near
the oven while you are cooking.
The microcomputer controlling your oven may temporarily become
scrambled and fail to function as programmed when you plug it 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 by resetting the clock.
Why is there light reflection around the
outer case?
This 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 heard when
the microwave oven is operating?
The clicking sound is caused by a mechanical switch turning the
microwave oven
ʼ
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.
