Frequently Asked Questions
About the Upper Oven
Q:
Can I use a rack in my upper oven to reheat or cook on two levels at once?
A:
Only use the rack that is supplied with your upper oven. Use of any other rack can result in poor
cooking performance and/or arcing and may damage your oven.
Q:
Will the upper oven be damaged if it operates while empty?
A:
Yes. Never operate the oven while it is empty or without the glass tray.
Q:
Does microwave energy pass through the viewing screen in the door?
A:
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.
Q:
Why do I see a light reflection around the outer case?
A:
This light is from the upper oven light which is located between the oven cavity and the outer wall of
the oven.
Q:
What are the various sounds I hear when the upper oven is operating?
A:
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.
Q:
Can my upper oven be damaged if food is cooked for too long?
A:
Like any other cooking appliance, it is possible to overcook food to the point that the food creates
smoke and even possibly fire, and damages the inside of the oven. It is always best to be near the
oven while you are cooking.
Q:
Why is a standing time recommended after microwave cooking time is over?
A:
Standing time allows foods to continue cooking evenly for a few minutes after the actual microwave
oven cooking cycle. The amount of standing time depends upon the density of the foods.
Q:
Why is additional time required for cooking food stored in the refrigerator?
A:
As in conventional cooking, the initial temperature of food affects total cooking time. You need more
time to cook food taken out of a refrigerator than for food at room temperature.
Q:
Can I use either metal or aluminum pans in my upper oven?
A:
Usable metal includes aluminum foil for shielding (use small, flat pieces), and shallow foil trays (if tray
is ¾ inch deep and filled with food to absorb microwave energy). Never allow metal to touch walls or
door.
Q:
Sometimes the door of my upper oven appears wavy. Is this normal?
A:
This appearance is normal and does not affect the operation of your oven.
Q:
Why does the glass tray not move?
