Answer

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 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.
