TROUBLESHOOTING

There may be several reasons why the oven light is not on.Have you:
• Set a cooking time?
• Touched START?
Make sure the microwave oven is plugged into a working outlet. Check for a
blown house fuse or tripped circuit breaker.
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
and then 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 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.
The fan will continue operating to cool the internal components of the pizza
oven.
