To request service information or replacement parts, the service center requires the complete model number of your microwave oven. The model number is on the oven back as shown in the illustration below.
The oven is designed to operate on a Standard 120V/60 Hz household outlet. Be sure the circuit is at least 15 A or 20 A and the microwave oven is the only appliance on the circuit. It is not designed for 50 Hz or any circuit other than a 120 V/60 Hz circuit. No other electrical appliances or lighting circuits should be on this line. If in doubt, consult a licensed electrician.
The voltage used at the wall receptacle must be the same as specified on the oven name plate located on the back or on the side of the control panel of the oven. Use of a higher voltage is dangerous and may result in a fire or other type of accident causing oven damage. Low voltage will cause slow cooking. If the microwave oven does not perform normally in spite of proper voltage, remove and reinsert the plug.
The microwave oven can be placed easily in your kitchen, family room, or anywhere else in your home. Place the oven on a flat surface such as a kitchen countertop or a specially designed microwave oven cart. Do not place oven above a gas or electric range. Free airflow around the oven is important. Allow at least 4 inches of space at the top, sides, and back of the oven for proper ventilation.
All air vents should be kept clear during cooking. If air vents are covered during oven operation the oven may overheat. If this happens, a sensitive thermal safety device automatically turns the oven off. The oven will be inoperable until it has cooled sufficiently.
This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.
Consult a qualified electrician or service person if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.
See the separate Installation Instructions for directions on placing the cord properly.
Keep the electrical power cord dry and do not pinch or crush it in any way.
Operating the microwave oven near equipment—such as a radio, TV, wireless LAN, Bluetooth devices, medical equipment, or wireless equipment—which uses the same frequency, may cause interference. This interference is not an indication of a defect in the product or its operation. The product is safe to use.
When there is interference, it may be reduced or eliminated by taking the following measures:
a. Clean the door and the sealing surfaces of the oven.
b. Reorient the receiving antenna of the radio, TV, Bluetooth, or other equipment.
c. Relocate the microwave oven in relation to the radio, TV, Bluetooth, or other equipment.
d. Move the microwave oven away from the receiver.
e. Plug the microwave oven into a different outlet so that microwave oven and receiver are on different branch circuits.

Use
OVENPROOF GLASS
(treated for high intensity heat):
utility dishes, loaf dishes, pie plates, cake plates, liquid measuring cups, casseroles and bowls without metallic trim.
CHINA:
bowls, cups, serving plates, and platters without metallic trim.
PLASTIC:
Plastic wrap (as a cover)- lay the plastic wrap loosely over the dish and press it to the sides.
Vent plastic wrap by turning back one edge slightly to allow excess steam to escape. The dish should be deep enough so that the plastic wrap will not touch the food. As the food heats it may melt the plastic wrap wherever the wrap touches the food.
Use plastic dishes, cups, semi-rigid freezer containers and plastic bags only for short cooking time. Use these with care because the plastic may soften from the heat of the food.
PAPER:
Paper towels, waxed paper, paper napkins, and paper plates with no metallic trim or design. Look for the manufacturer's label for use in the microwave oven.
Note:
Do not use recycled paper products in the microwave oven. They sometimes contain impurities that cause arcing and sparking.
Use Do Not Use
METAL CONTAINERS:
Metal shields the food from microwave energy and produces uneven cooking. Also avoid metal skewers, thermometers, or foil trays. Metal containers can cause arcing, which can damage the microwave oven.
METAL DECORATION:
Metal-trimmed or metal-banded dinnerware, casserole dishes, etc. The metal trim interferes with normal cooking and may damage the oven.
ALUMINUM FOIL:
Avoid large sheets of aluminum foil because they hinder cooking and may cause harmful arcing. Use small pieces of foil to shield poultry legs and wings. Keep ALL aluminum foil at least 1 inch from the side walls and door of the oven.
WOOD:
Wooden bowls and boards will dry out and may split or crack when you use them in the microwave oven. Baskets react in the same way.
TIGHTLY COVERED COOKWARE:
Be sure to leave openings for steam to escape from covered containers. Pierce plastic pouches of vegetables or other food items before cooking. Tightly closed pouches could explode.
BROWN PAPER:
Avoid using brown paper bags.
They absorb too much heat and could burn.
FLAWED OR CHIPPED UTENSILS:
Any container that is cracked, flawed, or chipped may break in the oven.
METAL TWIST TIES:
Remove metal twist ties from plastic or paper bags. They become hot and could cause a fire.
Never use metal or metal trimmed cookware when using microwave function
Microwaves cannot penetrate metal. They will bounce off any metal object in the oven and cause arcing, an alarming phenomenon that resembles lightning. Most heat resistant non-metallic cookware is safe for use in your oven. However, some may contain materials that render it unsuitable as microwave cookware. If you have any doubts about a particular container, there's a simple way to find out if it can be used in the microwave.
Testing Cookware before Use
Place the container in question next to a glass bowl filled with water inside the oven. Microwave at HIGH power for 1 minute. If the water heats up but the container remains cool to the touch, the container is microwave-safe.
However, if the water does not change temperature but the container becomes warm, microwaves are being absorbed by the container and it is not safe for use in the microwave oven. See the following list for tips on using common items when microwave cooking.
Tableware
Many dishes are microwave-safe. If in doubt consult the manufacturer's literature or perform the microwave test. Do not put plates with painted decoration in the oven, as the paint may contain metal and cause arcing.
Glassware
Glassware that is heat-resistant is microwave-safe. This includes all brands of oven tempered glass cookware.
Do not use delicate glassware, such as tumblers or wine glasses, as these might shatter as when heated.
Plastic Storage Containers
Use these only for quick reheating of food. Do not use them when cooking food for long periods or at high power levels, as the hot food will eventually warp or melt the plastic.
Paper
Paper plates and containers are convenient and safe to use in the microwave oven, provided that the cooking time is short and foods to be cooked are low in fat and moisture. Paper towels are also very useful for wrapping foods and for lining baking trays in which greasy foods such as bacon are cooked. In general, avoid colored paper products as the color may run. Some recycled paper products may contain impurities which could cause arcing or fires when used in the microwave.
Plastic Cooking Bags
Provided they are made specially for cooking, cooking bags are microwave safe. Remember to make a slit in the bag so that steam can escape. Never use ordinary plastic bags for cooking in the microwave oven, as they will melt and rupture.
Plastic Microwave Cookware
A variety of shapes and sizes of microwave cookware are available. You may be able to use items you already have on hand rather than investing in new kitchen equipment.
Pottery, Stoneware, and Ceramic
Many containers made of these materials are microwave-safe, but test them before use.
Keeping an Eye on Things
Always watch your food while it cooks. The light inside the microwave oven turns on automatically when the oven is cooking so you can monitor the cooking process. Directions given in recipes to elevate, stir, and the like should be thought of as the minimum steps recommended. If the food seems to be cooking unevenly, simply make the necessary adjustments you think appropriate to correct the problem.
Factors Affecting Microwave Cooking Times
Many factors affect cooking times. The temperature of ingredients used in a recipe makes a big difference in cooking times. For example, a cake made with ice-cold butter, milk, and eggs will take considerably longer to bake than one made with ingredients that are at room temperature. Some recipes, particularly those for bread, cake, and custards, recommend that food be removed from the oven when they are slightly undercooked.
This is not a mistake. When allowed to stand, usually covered, these foods will continue to cook outside of the oven as the heat trapped within the outer portions of the food gradually travels inward. If the food is left in the oven until it is cooked all the way through, the outer portions will become overcooked or even burnt.
Practice will improve your ability to estimate both cooking and standing times for various foods.
Density of Food
Light, porous food such as cakes and breads cook more quickly than heavy, dense foods such as roasts and casseroles. You must take care when microwaving porous food so that the outer edges do not become dry and brittle.
Height of Food
The upper portion of tall foods, particularly roasts, will cook more quickly than the lower portion.
Therefore, it is wise to turn tall food several times during cooking.
Moisture Content of Food
Because the heat generated from microwaves causes moisture to evaporate, relatively dry food such as roasts and some vegetables should either be sprinkled with water prior to cooking or covered to retain moisture.
Bone and Fat Content of Food
Bones conduct heat and fat cooks more quickly than meat. Care must be taken when cooking bony or fatty cuts of meat in order to prevent unevenly cooked or overcooked meat.
Quantity of Food
The number of microwaves in your oven remains constant regardless of how much food is being cooked. Therefore, the more food you place in the oven, the longer the required cooking time. Remember to decrease cooking times by at least one third when halving a recipe.
Shape of Food
Microwaves penetrate only about 3/4 of an inch (2 cm) into food. The interior portion of thick foods is cooked as the heat generated on the outside travels inward. Only the outer edge of food is cooked by microwave energy; the rest is cooked by conduction.
The worst possible shape for a food that is to be microwaved is a thick square. The corners will burn long before the center is even warm. Round thin foods and ring-shaped foods cook most successfully in the microwave.
Covering
A cover traps heat and steam which causes food to cook more quickly. Use a lid or microwave cling film with a corner folded back to prevent splitting.
Covering with Parchment Paper
Parchment paper (not waxed paper) is microwave safe. Because it makes a looser cover than a lid or clingfilm, greaseproof paper allows the food to dry out slightly.
Stirring
Stirring is one of the most important of all microwaving techniques. In conventional cooking, food is stirred for the purpose of blending. Microwaved food, however, is stirred in order to spread and redistribute heat. Always stir from the outside towards the centre as the outside of the food heats first.
Placing Thicker Portions Facing Outward
Place thicker cuts or portions of meat, poultry, and fish toward the outer edge of the baking dish so they absorb the most microwave energy and the food cooks more evenly.
Shielding
Strips of aluminium foil (which block microwaves) can be placed over the corners or edges of square and rectangular foods to prevent those portions from overcooking. Never use too much foil and make sure the foil is secured to the dish or it may cause arcing in the oven especially if the foil passes too closely to the walls of the oven during rotation.
Elevating
Thick or dense foods can be elevated so that microwaves can be absorbed by the underside and center of the foods.
Piercing
Foods enclosed in a shell, skin or membrane are likely to burst in the oven unless they are pierced prior to cooking. Such foods include yolks and whites of eggs, clams, oysters, potatoes, and other whole vegetables and fruits.
Testing if Cooked
Microwaves cook food quickly, so test food for doneness frequently. Some foods are left in the microwave until completely cooked, but most foods, including meats and poultry, should be removed from the oven while still slightly undercooked and allowed to finish cooking during standing time. The internal temperature of foods will rise between 5 °F (3 °C) and 15°F (8 °C) during standing time.
Standing Time
Foods are often allowed to stand for 3 to 10 minutes after being removed from the oven. Usually the foods are covered during standing time to retain heat unless they are supposed to be dry in texture. Standing allows foods to finish cooking and also helps flavors blend and develop.
This section introduces you to the basics you need to know to operate the microwave oven. Please read this information before using the oven.
Audible signals are available to guide you when setting and using the oven:

Interior
Food spatters or spilled liquids stick to oven walls and between the seal and door surfaces. Although the oven interior has an actibacterial coating, it is best to wipe up spillovers with a damp cloth right away.
Crumbs and spillovers will absorb microwave energy and lengthen cooking times and may even damage the oven. Use a damp cloth to wipe out crumbs that fall between the door and the frame. It is important to keep this area clean to assure a tight seal. Remove greasy spatters with a soapy cloth then rinse and dry.
Do not use harsh detergent or abrasive cleaners.
Anti-bacterial claim based on internal testing with e-coli and Staphylococcus bacteria, showing coating prevents 99.99 % of bacterial growth on the surface of the cavity of NeoChef.
Exterior
Disconnect the plug from the power outlet before cleaning the oven to eliminate the possibility of electric shock. Clean the outside of your oven with soap and water then with clean water and dry with a soft cloth or paper towel. To prevent damage to the operating parts inside the oven, the water should not be allowed to seep into the ventilation openings.
To clean control panel, open the door to prevent the oven from accidentally starting, and wipe with a damp cloth followed immediately by a dry cloth. Press STOP after cleaning.
If steam accumulates inside or around the outside of the oven door, wipe the panels with a soft cloth.
Steam or condensation buildup inside the door is normal if foods are heated for a long period on higher power levels. This is not a malfunction. The condensation will eventually evaporate. Try covering the food or varying the heating levels and time to reduce any condensation forming in the door. This may also occur when the oven is operated under high humidity conditions and in no way indicates a malfunction of the unit.
The door and door seals should be kept clean. Use only warm, soapy water, rinse then dry thoroughly. DO NOT USE ABRASIVE MATERIALS, SUCH AS CLEANING POWDERS OR STEEL AND PLASTIC PADS.
Metal parts will be easier to maintain if wiped frequently with a damp cloth.
To clean the glass tray and rotating ring, wash in mild, sudsy water.
For heavily soiled areas use a mild cleanser and scouring sponge.
The glass tray and rotating ring are dishwasher safe.
Operation
Why is the oven light not on during cooking?
Make sure the cooking time has been set and the START button has been pressed.
Why does steam come out of the air exhaust vent?
Steam is normally produced during cooking. The microwave oven has been designed to vent this steam.
Will the microwave 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 does a tone sound when a pad on the control panel is touched?
The tone tells you that the setting has been entered.
Can my microwave 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.
I've plugged the oven in and it does not work properly. What is wrong?
The microcomputer controlling your oven may temporarily become scrambled and fail to function as programmed when you plug the oven in for the first time or when power resumes after a power interruption. Unplug the oven from the 120 V household outlet and then plug it back in to reset the microcomputer.
Why do I see light reflection around the outer case?
This light is from the 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 microwave 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.
Food
Is it possible to pop popcorn in a microwave oven?
Yes, if using one of the two methods described below:
Follow exact directions given by each manufacturer for its popcorn popping product and do not leave the oven unattended while the corn is being popped. If corn fails to pop after the suggested time, discontinue cooking. Overcooking could result in an oven fire.
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.
You can often correct operating problems yourself. If your microwave oven fails to work properly, locate the operating problem in the list below and try the solutions listed for each problem.
If the microwave oven still does not work properly, contact the nearest LG Authorized Service Center. LG
