Read the Service Manual carefully and follow all instructions. Before Servicing 1. Disconnect the power supply cord remove cabinet. 2. Open the drawer and keep it open. 3. Discharge high voltage capacitor. , and then WARNING: RISK OF ELECTRIC SHOCK. DISCHARGE THE HIGH-VOLTAGE CAPACITOR BEFORE SERVICING. The high-voltage capacitor remains charged about 60 seconds after the oven has been switched off. Wait for 60 seconds and then short-circuit the connection of the high-voltage capacitor (that is the connecting lead of the high-voltage rectifier) against the chassis with the use of an insulated screwdriver. When the testing is completed, 1. Disconnect the power supply cord, and then remove covers. 2. Open the drawer and keep it open. 3. Discharge high voltage capacitor. 4. Reconnect the leads to the primary of the power transformer. 5. Reinstall the covers. 6. Reconnect the power supply cord. 7. Run the unit and check all functions. After repairing 1. Reconnect all leads removed from components during testing. 2. Reinstall the covers. 3. Reconnect the power supply cord. 4. Run the oven and check all functions. Whenever troubleshooting is performed the power supply must be disconnected. It may, in some cases, be necessary to connect the power supply after the outer case has been removed, in this event: 1. Disconnect the power supply cord, and then remove neccessary covers. 2. Open the drawer and keep it open. 3. Discharge high voltage capacitor. 4. Disconnect the leads to the primary of the power transformer. 5. Ensure that the leads remain isolated from other components and oven chassis by using insulation tape. 6. After that procedure, reconnect the power supply cord. Microwave ovens should not be operated empty. To test for the presence of microwave energy within a cavity, place a cup of cold water on the oven tray, close the drawer and set the power to HIGH and set the microwave timer for two (2) minutes. When the two minutes has elapsed (timer at zero) carefully check that the water is now hot. If the water remains cold carry out Before Servicing procedure and re-examine the connections to the component being tested. When all service work is completed and the oven is fully assembled, the microwave power output should be checked and a microwave leakage test should be carried out. KB-3401LS KB-3401LK KB-3401LW SAFE SERVICING PRACTICES To avoid personal injury and/or property damage, it is important that Safe Servicing Practices be observed. The following are some limited examples of safe practices: 1. DO NOT attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory manner. 2. Before servicing or moving an appliance: • Remove the power cord from the electrical outlet, trip the circuit breaker to the OFF position, or remove the fuse. 3. Never interfere with the proper operation of any safety device. 4. USE ONLY SHARP AUTHORIZED PARTS FOR THIS APPLIANCE. SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY STANDARDS SET FOR HOME APPLIANCES. 5. GROUNDING : The standard color coding for safety ground wires is GREEN , or GREEN with YELLOW STRIPES . Ground leads are not to be used as current carrying conductors. It is EXTREMELY important that the service technician reestablish all safety grounds prior to completion of service. Failure to do so will create a hazard. 6. Prior to returning the product to service, ensure that: • • • • • All electrical connections are correct and secure All electrical leads are properly dressed and secured away from sharp edges, high-temperature components, and moving parts All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal parts and panels All safety grounds (both internal and external) are correctly and securely connected All panels are properly and securely reassembled ATTENTION!!!

Sharp Electronics Corporation cannot be responsible, nor assume any liability, for injury or damage of any kind arising from the use of this manual. KB-3401LS KB-3401LK KB-3401LW MICROWAVE MEASUREMENT PROCEDURE A. Requirements: 1) Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven should not exceed 1mW/cm2 at any point 5cm or more from the external surface of the oven, measured prior to acquisition by a purchaser, and thereafter (through the useful life of the oven), 5 mW/cm2 at any point 5cm or more from the external surface of the oven. 2) Safety interlock switches: Primary interlock relay switch shall prevent microwave radiation emission in excess of the requirement as above mentioned. Secondary interlock relay and door sensing switch shall prevent microwave radiation emission in excess of 5 mW/cm2 at any point 5cm or more from the external surface of the oven. B. Preparation for testing: Before beginning the actual measurement of leakage, proceed as follows: 1) Make sure that the actual instrument is operating normally as specified in its instruction booklet. Important: Survey instruments that comply with the requirement for instrumentation as prescribed by the performance standard for microwave ovens, 21 CFR 1030.10(c)(3)(i), must be used for testing. 2) Place the load of 275±15 ml (9.8 oz) of tap water initially at 20±5O C (68OF) in the center of the oven cavity. The water container shall be a low form of 600 ml (20 oz) beaker with an inside diameter of approx. 8.5 cm (3-1/2 in.) and made of an electrically nonconductive material such as glass or plastic. The placing of this standard load in the oven is important not only to protect the oven, but also to insure that any leakage is measured accurately. 3) Set the cooking control on Full Power Cooking Mode. 4) Close the drawer and select a cook cycle of several minutes. If the water begins to boil before the survey is completed, replace it with 275 ml of cool water. C. Leakage test: Closed-drawer leakage test (microwave measurement): 1) Grasp the probe of the survey instrument and hold it perpendicular to the gap between the drawer and the body of the oven. 2) Move the probe slowly, not faster than 1 in./sec. (2.5 cm/sec.) along the gap, watching for the maximum indication on the meter. 3) Check for leakage at the drawer screen, sheet metal seams and other accessible positions where the continuity of the metal has been breached (eg., around the switches, indicator, and vents). While testing for leakage around the drawer, pull the drawer away from the front of the oven as far as is permitted by the closed latch assembly. 4) Measure carefully at the point of highest leakage and make sure that the highest leakage is no greater than 4mW/cm2, and that the primary interlock switch/secondary interlock relay does turn the oven OFF before any door movement.

Employing lead-free solder The "Main PWB" of this model employs lead-free solder. This is indicated by the "LF" symbol printed on the PWB and in the service manual. The suffix letter indicates the alloy type of the solder. Example: Indicates lead-free solder of tin, silver and copper. 2. Using lead-free wire solder When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may result in cold soldered joints and damage to printed patterns.) As the melting point of lead-free solder is approximately 40oC higher than tin/lead alloy solder, it is recommend that a dedicated bit is used, and that the iron temperature is adjusted accordingly. 3. Soldering As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wettability, (flow), to prevent damage to the land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time. Remove the bit as soon as a good flow is achieved. The high content of tin in lead free solder will cause premature corrosion of the bit. To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required. Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their characteristics, making good soldering more difficult. It will be necessary to clean and replace bits more often when 22 KB-3401LS KB-3401LK KB-3401LW OVEN / MICROWAVE DRAWER DISASSEMBLY WARNING: Follow all safety precautions beginning on Page 2 before proceeding!
