Daewoo KOR07R3ZEC - User Manual

This document provides comprehensive operating instructions and a cook book for the DAEWOO Microwave Oven, specifically models KOR07R3ZEC, KOR07R3ZEL, KOR07R3ZEM, and KOR07R3ZER. It emphasizes safety precautions, proper installation, and detailed usage guidelines to ensure efficient and safe operation.

The microwave oven is designed for heating, cooking, or drying food. It is not intended for industrial or laboratory use. Users are strongly advised to read the entire manual before operating the oven to prevent potential hazards and ensure optimal performance.

Function Description

The DAEWOO Microwave Oven utilizes microwave energy to cook and reheat food. Microwaves cause water molecules in food to vibrate, generating heat through friction, which then cooks the food from the outside inwards. The oven features a magnetron that converts electricity into microwaves, which then bounce off the metal walls and door screen of the oven cavity. These microwaves pass through cooking containers and are absorbed by the water molecules in the food.

The control panel includes a display for cooking time, power level, and indicators. It offers various cooking modes:

Microwave Cook: This feature allows users to cook food with microwave energy, with adjustable power levels ranging from 100% to 20%. The power level can be selected by pressing the "Power" button, and the cooking time can be set using the dial knob, up to 60 minutes. Lower power levels are recommended for delicate foods like cheese, milk, and for slow cooking meats.
+30 Sec: This function allows for quick reheating for 30 seconds at full power. Repeatedly pressing the "+30sec" button can extend reheating time up to 5 minutes in 30-second increments.
Auto Cook: This mode provides pre-programmed settings for cooking or reheating popular foods. Users can select from various menu programs (e.g., Beverage, Soup, Baked Potato, Fresh Vegetable, Frozen Vegetable) and adjust the desired quantity using the dial knob.
Weight Defrost: This feature simplifies defrosting by eliminating the need to guess defrosting times. Users input the weight of the food (minimum 0.2 lb, maximum 3.5 lb), and the oven automatically calculates the defrosting time. During the cycle, the oven beeps to prompt the user to turn or rearrange the food.
Time Defrost: This mode allows users to manually set the defrosting time, up to 60 minutes. The oven cycles between defrosting and stand times, with beeps indicating when to turn or rearrange the food.
Popcorn: Dedicated button for cooking popcorn. Users select the package size (1.75oz or 3.5oz), and the oven automatically sets the cooking time. It is crucial to use prepackaged, room-temperature microwave popcorn and to avoid reheating unpopped kernels or reusing bags. The manual advises against leaving the oven unattended during popcorn preparation.

The oven also incorporates an (ECO mode) STAND-BY feature to reduce stand-by power consumption. If left unused for 2 minutes after finishing a task, the oven automatically turns off. Opening the door will reactivate the display and prepare the oven for use.

Usage Features

The microwave oven is designed for user convenience and safety.

Door Latch and Seal: The door latches securely when closed, and the door seal prevents microwaves from escaping the oven cavity. If the door is opened during operation, the magnetron automatically shuts off.
Oven Lamp: The interior oven lamp automatically turns on when the oven is operating, allowing users to monitor their food.
Roller Guide and Glass Cooking Tray: These components must always be in place during cooking to ensure even heating. The glass tray is made of special heat-resistant glass and rotates to distribute heat uniformly. Food should not be cooked directly on the tray, except for popcorn in its designated bag.
Viewing Screen: The screen allows users to view food while cooking. It is designed to let light pass through but blocks microwaves.
Waveguide Cover: This protects the microwave outlet from splashes of cooking foods, ensuring consistent performance.
Safety Interlock System: This system prevents the oven from operating if the door is not properly closed, enhancing user safety.
Audible Feedback: Each button press is acknowledged with a "BEEP" sound. At the end of a cooking cycle, the oven emits three beeps.
Standing Time: After cooking, a standing time is recommended for many foods (e.g., meat, jacket potatoes, cakes) to allow residual heat to cook the center completely. This also applies to defrosted food.
Stirring and Turning: Liquids should be stirred before and during heating to prevent eruption. Meat and poultry should be turned halfway through cooking for even results.
Arranging Food: Individual food items, such as chicken portions, should be arranged on a dish with thicker parts towards the outside for uniform cooking.
Piercing: Foods with non-porous skins or membranes (e.g., eggs, potatoes, apples, sausages) must be pierced before cooking to prevent steam buildup and bursting.
Covering: Covering foods with microwave cling film or a lid helps retain moisture and speeds up cooking times. However, care should be taken when removing cling film due to hot steam.

Maintenance Features

Regular cleaning and proper maintenance are essential for the longevity and safe operation of the microwave oven.

General Cleaning: The oven should be cleaned regularly, and all food deposits removed. Failure to do so can lead to deterioration of surfaces and potentially hazardous situations.
Interior Cleaning: Oven walls should be wiped with a damp cloth after each use. Mild detergent can be used for stubborn stains. Abrasive powders or pads are not recommended.
Exterior Cleaning: The outside surface should be cleaned with soap and water, then rinsed and dried with a soft cloth. Water should not seep into the ventilation openings.
Control Panel: If the control panel gets wet, it should be cleaned with a soft, dry cloth. Harsh detergents or abrasives should not be used on the control panel.
Steam Accumulation: Steam accumulating inside or around the door is normal under high humidity conditions and does not indicate a malfunction. It should be wiped with a soft cloth.
Glass Tray and Roller Guide: These parts should be removed and washed regularly in warm, sudsy water or a dishwasher. The oven cavity floor beneath the roller guide should also be cleaned with mild detergent water or window cleaner and dried.
Waveguide Cover: The waveguide cover must be kept clean at all times to prevent grease or fat buildup, which could lead to overheating, smoke, or fire.
Troubleshooting: The manual includes a "BEFORE YOU CALL FOR SERVICE" checklist to help users identify and resolve common issues, such as the oven not working or sparking in the cavity, before contacting customer service. Users are explicitly warned not to attempt to service the oven themselves.

The manual also provides a "Utensil Guide" to help users select microwave-safe containers, emphasizing that metal or foil should not touch the oven walls to prevent arcing. It also advises against heating corrosive chemicals in the oven, as their vapors can damage safety interlock switches.
