Using the Proper Cookware
The size and type of cookware will influence the settings needed for the best cooking results. Be sure to follow the recommendations for using proper cookware.
Cookware should have flat bottoms that make good contact with the entire surface heating element. Check for flatness by placing a ruler across the bottom of the cookware. The ruler should touch the cookware across the entire bottom, with no gaps.

Cookware Recommendations
Cookware should not

NOTE
Do not use pans less than 7 inches in diameter on the front elements.
Do not use foil or foil-type containers. Foil may melt onto the glass. Do not use the cooktop if metal has melted on it. Call an authorized LG Service Center.
Choosing Cookware
The cookware material determines how evenly and quickly heat is transferred from the surface element to the pan bottom. The most popular materials available are:
Home Canning Tips
Oven Vent
Areas near the vent may become hot during operation and may cause burns. Do not block the vent opening. Avoid placing plastics near the vent as heat may distort or melt the plastic.
It is normal for steam to be visible when cooking foods with high moisture content.

Using Oven Racks
The racks have a turned-up back edge that prevents them from being pulled out of the oven cavity.
Removing Racks
Replacing Racks
Bake
Bake is used to prepare foods such as pastries, breads and casseroles. The oven can be programmed to bake at any temperature from 170 °F (80 °C) to 550 °F (285 °C). The default temperature is 350 °F (175 °C).

Use ceramic cooktop cleaner on the glass cooktop.
Other creams may not be as effective or may scratch, damage or stain the cooktop surface.
To maintain and protect the surface of the glass cooktop, follow these steps:
Burned-On Residue
1 While the cooktop is still hot, remove any burnt on deposits or spilled food from the glass-ceramic cooking surface with a suitable metal razor scraper. (Similar to scraping paint off of a windowpane, it will not damage the decorated cooking surface.) Hold the scraper at an approximate 30° angle to the cooktop.

2 When the cooking surface has cooled down, apply a few dabs (about the size of a dime) of an approved cleaner in each burner area and work the cleaning cream over the cooktop surface with a damp paper towel.

3 Rinse with clean water and wipe the cooktop surface with a clean, dry paper towel.

LG’s EasyClean® enamel technology provides two cleaning options for the inside of the lower oven. The EasyClean® feature takes advantage of LG’s new enamel to help lift soils without harsh chemicals, and it runs using ONLY WATER for just 10 minutes in low temperatures to help loosen LIGHT soils before hand cleaning.
While EasyClean® is quick and effective for small and LIGHT soils, the Self Clean feature can be used to remove HEAVY, built up soils. The intensity and high heat of the Self Clean cycle may result in smoke which will require the opening up of windows to provide ventilation. Compared to the more intense Self Clean process, your LG oven gives you the option of cleaning with LESS HEAT, LESS TIME, and virtually NO SMOKE OR FUMES.
When needed, the oven still provides the Self Clean option for longer, more thorough oven cleaning for heavier, built up soils.
Benefits of EasyClean®

Cleaning Tips
Self Clean
The Self Clean cycle uses extremely hot temperatures to clean the oven cavity. While running the Self Clean cycle, you may notice smoking or an odor. This is normal; especially if the oven is heavily soiled.
During Self Clean, the kitchen should be well ventilated to minimize the odors from cleaning.
Setting Self Clean
The Self Clean function has cycle times of 3, 4, or 5 hours.
Self Clean Soil Guide
CAUTION
Do not force the oven door open when the lock icon is displayed. The oven door remains locked until the oven temperature has cooled. Forcing the door open will damage the door.
Setting Self Clean with a Delayed Start
During Self Clean
After the Self Clean Cycle
Changing the Oven Light
The oven light is a standard 40-watt appliance bulb. It turns on when the oven door is open. When the oven door is closed, press Light to turn it on or off.

Cleaning the Exterior
Painted and Decorative Trim
For general cleaning, use a cloth with hot soapy water. For more difficult soils and built-up grease, apply a liquid detergent directly onto the soil. Leave it on for 30 to 60 minutes. Rinse with a damp cloth and dry. Do not use abrasive cleaners.
Stainless Steel Surfaces
To avoid scratches, do not use steel wool pads.
Oven Door

Broiler Pan and Grid

Oven Racks
Remove the oven racks before operating the self clean cycle.
1 Food spilled into the tracks could cause the racks to become stuck. Clean racks with a mild, abrasive cleaner.
2 Rinse with clean water and dry
Removing and Replacing the Lift-Off Oven Doors and Drawer
Removing the Door
1 Open the door fully.
2 Pull the hinge locks down toward the door frame to the unlocked position.

3 Firmly grasp both sides of the door at the top.
4 Close door to the door removal position, which is approximately 5 degrees.

5 Lift door up and out until the hinge arm is clear of the slot.
Replacing the Door
1 Firmly grasp both sides of the door at the top.
2 With the door at the same angle as the removal position, seat the indentation of the hinge arm into the bottom edge of the hinge slot. The notch in the hinge arm must be fully seated into the bottom of the slot.

3 Open the door fully. If the door will not open fully, the indentation is not seated correctly in the bottom edge of the slot.
4 Push the hinge locks up against the front frame of the oven cavity to the locked position.

5 Close the oven door.
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.
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.
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.
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.
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 lock will show in the display if Lockout is activated. To deactivate Lockout, touch and hold Lower Clear/Off for three seconds. The unlock melody sounds and Loc appears in the display until the controls are unlocked.
My oven is still dirty after running the EasyClean® cycle. What else should I do?
The EasyClean® cycle only helps to loosen light soils in your oven to assist in hand-cleaning of your oven. It does not automatically remove all soils after the cycle. Some scrubbing of your oven is required after running the EasyClean® cycle.
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.
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.
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.
