Owner's Guide Microwaves
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 120 V/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.
Warning
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.
NOTE
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.
Warning
When there is interference, it may be reduced or eliminated by taking the following measures:

OVENPROOF GLASS CHINA: PLASTIC: 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 times. Use these with care because the plastic may soften from the heat of the food. PAPER: Note: |
METAL CONTAINERS: METAL DECORATION: ALUMINUM FOIL: WOOD: TIGHTLY COVERED COOKWARE: BROWN PAPER: FLAWED OR CHIPPED COOKWARE: Any container that is cracked, flawed, or chipped may break in the oven. METAL TWIST TIES: |
Never use metal or metal-rimmed cookware in the microwave oven.
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 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.
CAUTION
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.
− Do not pop popcorn, except in a microwave-safe container or commercial packages designed for microwave ovens.
− Never try to pop popcorn in a paper bag that is not microwave-approved.
− Overcooking may result in smoke and fire.
− Do not repop unpopped kernels.
− Do not reuse popcorn bags.
− Listen while corn pops. Stop oven when popping slows to 2-3 seconds between pops.
− Do not leave microwave unattended while popping corn.
− Follow directions on bag.

Use the following table if necessary to convert food weights to decimals.

Interior
Food spatters or spilled liquids stick to oven walls and between the seal and door surfaces. Although the oven interior has an antibacterial 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/Clear 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.
NOTE
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/Enter/+30 sec. 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:
(1) microwave-popping devices designed specifically for microwave cooking
(2) prepackaged commercial microwave popcorn that specifies the cook time and power output needed.
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.
CAUTION
Never use a brown paper bag for popping corn or attempt to pop leftover kernels.
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.
