TROUBLESHOOTING

There may be several reasons why the oven light is not on.
Have you:
• Set a cooking time?
• Touched START?
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 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.
This light is from the oven light which is located between the
oven cavity and the outer wall of the 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
themagnetron 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.
A hard, dry, brown spot indicates overcooking. Shorten the
cooking or reheating time.
When baking, frying, or poaching eggs, the yolk may pop due to
steam build-up inside the yolk membrane. To prevent this, simply
pierce the yolk before cooking.
CAUTION: Never microwave eggs in the shell.
