FAQs
Can I use a rack in my upper oven to reheat or cook on two levels at once?
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.
Will the upper oven be damaged if it operates empty?
Yes. Never operate the oven empty or without the glass tray.
Does microwave energy pass through the viewing screen in the door?
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.
Why do I see light reflection around the outer case?
This light is from the upper oven light which is located between the oven cavity and the outer wall of the oven.
What are the various sounds I hear when the upper oven is operating?
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.
Can my upper oven be damaged if food is cooked for too long?
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.
Why is a standing time recommended after microwave cooking time is over?
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.
Why is additional time required for cooking food stored in the refrigerator?
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.
Can I use either metal or aluminum pans in my upper oven?
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.
Sometimes the door of my upper oven appears wavy. Is this normal?
This appearance is normal and does not affect the operation of your oven.
The glass tray does not move.
The glass tray is not correctly in place. It should be correct-side up and sitting firmly on the center hub. The support is not operating correctly. Remove the glass tray and restart the oven. Cooking without the glass tray can give you poor results.
Why does the dish become hot when I microwave food in it? I thought that this should not happen.
As the food becomes hot it will conduct the heat to the dish. Use hot pads to remove food after cooking.
What does standing time mean?
Standing time means that food should be taken out of the oven and covered for additional time after cooking. This process allows the cooking to finish, saves energy, and frees the oven for other purposes.

Can I pop popcorn in my upper oven? How do I get the best results?
Yes. Pop packaged microwave popcorn following manufacturer’s guidelines or use the preprogrammed Popcorn key. Do not use regular paper bags. Use the listening test by stopping the oven as soon as the popping slows to a pop every one or two seconds. Do not try to repop unpopped kernels. You can also use special microwave poppers. When using a popper, be sure to follow manufacturer’s directions. Do not pop popcorn in glass utensils.
Why does steam come out of the air exhaust vent?
Steam is normally produced during cooking. The upper oven has been designed to vent steam out of the top vent.
The Lower oven doesn’t cook like my old one. Is there something wrong with the temperature settings?
No, your oven has been factory tested and calibrated. For the first few uses, follow your recipe times and temperatures carefully. If you still think your new oven is too hot or too cold, you can adjust the oven temperature yourself to meet your specific cooking needs. Refer to the Oven Temperature Adjustment section in this manual for easy instructions on how to adjust your thermostat.
Can I use aluminum foil to catch drippings in the lower oven cavity?
Never use aluminum foil to line the bottom or sides of the oven. The foil will melt and stick to the bottom surface of the oven and will not be removable. Use a sheet pan placed on a lower oven rack to catch drippings instead. (If foil has already melted onto the bottom of the oven, it will not interfere with the oven's performance.)
Can I use aluminum foil on the racks?
Do not cover racks with aluminum foil. Covering entire racks with foil restricts air flow, leading to poor cooking results. Use a sheet pan lined with foil under fruit pies or other acidic or sugary foods to prevent spillovers from damaging the oven finish.
CAUTION
Foil may be used to wrap food in the lower oven, but do not allow the foil to come into contact with the exposed heating/broiling elements in the oven. The foil could melt or ignite, causing smoke, fire, or injury.
Can I leave my racks in the oven when running a Self Clean cycle?
No. Although it will not damage the racks, it will discolor them and may make them hard to slide in and out during use. Remove all items from the oven before starting a Self Clean cycle.
ENGLISH
Is it normal to hear a clicking noise coming from the back of the lower oven when I am using it?
Your new oven is designed to maintain a tighter control over your oven’s temperature. You may hear your oven’s heating elements click on and off more frequently on your new oven. This is NORMAL.
Why is the time flashing?
This means that the product has just been plugged in, or that it has experienced a power interruption. To clear the flashing time, touch any button and reset the clock if needed.
During convection cooking the fan stops when I open the door. Is that normal?
Yes, this is normal. When the door is opened, the convection fan will stop until the door is closed.
What should I do if my racks are sticky and have become hard to slide in and out?
Over time, the racks may become hard to slide in and out. Apply a small amount of olive oil to the ends of the racks. This will work as a lubricant for easier gliding.
Why aren't the function buttons working?
Make sure that the oven is not in Lockout mode. The

TROUBLESHOOTING
I tried scrubbing my oven after running EasyClean®, but some soils still remain. What can I do?
®
The EasyClean
feature works best when the soils are fully soaked and submerged in water before running the cycle and during hand-cleaning. If soils are not sufficiently soaked in water, it can negatively affect the cleaning performance. Repeat the
®
EasyClean
process using sufficient water. Sugar-based and certain greasy soils are especially hard to clean. If some stubborn soils remain, use the Self Clean feature to thoroughly clean your oven.
Soil on the oven walls is not coming off. How can I clean the oven walls?
Soils on the side and rear walls of your oven may be more difficult to fully soak with water. Try repeating
®
the EasyClean
process with more than the ¼ cup
(2 oz or 60 ml).
®
Will EasyClean
get all of the soils and stains out
completely?
It depends on the soil type. Sugar-based and certain grease stains are especially hard to clean. Also, if stains are not sufficiently soaked in water, this can negatively affect cleaning performance. If stubborn or built-up stains remain, use the Self Clean feature. Refer to the Self Clean section of your owner's manual.
I see smoke coming out of my oven's vents
®
during EasyClean
. Is this normal?
This is normal. This is not smoke. It is actually water vapor (steam) from the water in the oven cavity. As
®
the oven heats briefly during EasyClean
, the water in the cavity evaporates and escapes through the oven vents.
®
How often should I use EasyClean
®
EasyClean
can be performed as often as you wish.
?
EasyClean® works best when your oven is LIGHTLY soiled from such things as LIGHT grease splatter and small drops of cheese. Please refer to the EasyClean® section in your owner's manual for more information.
®
What is required for EasyClean
?
A plastic scraper, a non-scratch scrubbing pad and a towel. You should not use abrasive scrubbers such as heavy-duty scouring pads or steel wool. Except for a towel, all of the materials you need are included in a special cleaning kit with your new oven.
Are there any tricks to getting some of the stubborn soils out?
Scraping the soils with a plastic scraper before and during hand-cleaning is recommended. Fully saturating soils with water is also recommended. However, certain types of soils are harder to clean than others. For these stubborn soils, the Self Clean cycle is recommended. Consult the Self Clean section of your owner's manual for details.
Is it safe for my convection fan, broil burner or
®
heater element to get wet during EasyClean
?
Yes. The convection fan, broiler burner or heater element may get a little wet during cleaning. However, direct spray onto the broil burner and heater elements is not necessary because these are self-cleaning during regular use.
