R-1872 PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY (a) Do not operate or allow the oven to be operated with the door open. (b) Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source, and make repairs as necessary: (1) interlock operation (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse. (c) Before turning on microwave power for any service test or inspection within the microwave generating compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections. (d) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner. (e) A microwave leakage check to verify compliance with the Federal Performance Standard should be performed on each oven prior to release to the owner. BEFORE SERVICING Before servicing an operative unit, perform a microwave emission check as per the Microwave Measurement Procedure outlined in this service manual. If microwave emissions level is in excess of the specified limit, contact SHARP ELECTRONICS CORPORATION immediately @1-800-237-4277. If the unit operates with the door open, service person should 1) tell the user not to operate the oven and 2) contact SHARP ELECTRONICS CORPORATION and Food and Drug Administration's Center for Devices and Radiological Health immediately. Service personnel should inform SHARP ELECTRONICS CORPORATION of any certified unit found with emissions in excess of 4mW/cm2. The owner of the unit should be instructed not to use the unit until the oven has been brought into compliance. R-1872 WARNING TO SERVICE PERSONNEL Microwave ovens contain circuitry capable of producing very high voltage and current, contact with following parts may result in a severe, possibly fatal, electrical shock. (Example) High Voltage Capacitor, High Voltage Power Transformer, Magnetron, High Voltage Rectifier Assembly, High Voltage Harness etc.. Read the Service Manual carefully and follow all instructions. Don't Touch ! Danger High Voltage When the testing is completed, 1. Disconnect the power supply cord, and then remove outer case. 2. Open the door and block it open. 3. Discharge high voltage capacitor. 4. Reconnect the leads to the primary of the power transformer. 5. Reinstall the outer case (cabinet). 6. Reconnect the power supply cord after the outer case is installed. 7. Run the oven and check all functions. Before Servicing 1. Disconnect the power supply cord remove outer case. 2. Open the door and block it open. 3. Discharge high voltage capacitor. , and then WARNING:RISK OF ELECTRIC SHOCK. DISCHARGE THE HIGH-VOLTAGE CAPACITOR BEFORE SERVICING. After repairing 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 highvoltage capacitor (that is the connecting lead of the highvoltage rectifier) against the chassis with the use of an insulated screwdriver. 1. Reconnect all leads removed from components during testing. 2. Reinstall the outer case (cabinet). 3. Reconnect the power supply cord after the outer case is installed. 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 outer case. 2. Open the door and block 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 run empty. To test for the presence of microwave energy within a cavity, place a cup of cold water on the oven turntable, close the door 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 reexamine 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. 1 R-1872 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 and door sensing switch shall prevent microwave radiation emission in excess of the requirement as above mentioned, secondary interlock 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 oven tray in the oven cavity. 3) Place the load of 275±15 ml (9.8 oz) of tap water initially at 20±5½C (68½F) 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. 4) Set the cooking control on Full Power Cooking Mode. 5) Close the door 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-door leakage test (microwave measurement) 1) Grasp the probe of the survey instrument and hold it perpendicular to the gap between the door 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 door 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 door pull the door 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 secondary interlock switch does turn the oven OFF before any door movement. NOTE: After servicing, record data on service invoice and microwave leakage report. 2 R-1872 PRODUCT DESCRIPTION SERVICE MANUAL GENERAL INFORMATION MICROWAVE OVEN R-1872 OPERATION FOREWORD This Manual has been prepared to provide Sharp Electronics Corp.

(1) When the door opens from a closed position, the secondary interlock relay, door sensing switch, primary and secondary switch open their contacts, and then the monitor switch contacts close. (2) When the door is closed from the open position, the monitor switch contacts first open, and then the contacts of the primary and secondary switch close. If the primary switch, secondary switch and secondary interlock relay fail with their contacts closed when the door is opened, the closing of the monitor switch contacts will form a short circuit through the monitor fuse, secondary switch switch, primary switch and secondary interlock relay, causing the monitor fuse to blow. The following is a description of component functions during oven operation. OFF CONDITION Closing the door activates the door sensing switch and secondary interlock switch. (In this condition, the monitor switch contacts are opened.) When oven is plugged in, 120 volts A.C. is supplied to the control unit. (Figure O-1). 1. The display will show SHARP, SIMPLY, THE, BEST, PRESS, CLEAR, and PRESS, CLOCK. To set any program or set the clock, you must first touch the STOP/CLEAR pad. The display will clear, and " : " will appear. COOKING CONDITION POWER LEVEL P-0 TO P-90 COOKING Program desired cooking time touching the NUMBER pads. When the START pad is touched, the following operations occur: When Variable Cooking Power is programmed, the 120 volts A.C. is supplied to the power transformer intermittently through the contacts of relay (RY2) which is operated by the control unit within an interval second time base. Microwave power operation is as follows: 1. The contacts of relays are closed and components connected to the relays are turned on as follows. (For details, refer to Figure O-2) RELAY RY1 RY2 RY4 RY5 VARI-MODE ON TIME Power 10(P-HI) 32 sec. (100% power) Power 9(P-90) 30 sec. (approx. 90% power) Power 8(P-80) 26 sec. (approx. 80% power) Power 7(P-70) 24 sec. (approx. 70% power) Power 6(P-60) 22 sec. (approx. 60% power) Power 5(P-50) 18 sec. (approx. 50% power) Power 4(P-40) 16 sec.

(0% power) CONNECTED COMPONENTS Oven lamp Power transformer/ Stirrer motor Turntable motor Fan motor 2. 120 volts A.C. is supplied to the primary winding of the power transformer and is converted to about 3.3 volts A.C. output on the filament winding, and approximately 2000 volts A.C. on the high voltage winding. 3. The filament winding voltage heats the magnetron filament and the H.V. winding voltage is sent to a voltage doubler circuit. 4. The microwave energy produced by the magnetron is channelled through the waveguide into the cavity feedbox, and then into the cavity where the food is placed to be cooked. 5. Upon completion of the cooking time, the power transformer, oven lamp, etc. are turned off, and the generation of microwave energy is stopped. The oven will revert to the OFF condition. 6. When the door is opened during a cook cycle, monitor switch, door sensing switch, primary switch and secondary switch and secondary interlock relay are activated with the following results. The circuits to the stirrer motor, the cooling fan motor, the turntable motor, and the high voltage components are de-energized, and the digital read-out displays the time still remaining in the cook cycle when the door was opened. 7. The monitor switch is electrically monitoring the operation OFF TIME 0 sec. 2 sec. 6 sec. 8 sec. 10 sec. 14 sec. 16 sec. 20 sec. 24 sec. 26 sec. 32 sec. Note: The ON/OFF time ratio does not correspond with the percentage of microwave power, because approx. 2 seconds are needed for heating of the magnetron filament. 6 R-1872 SCHEMATIC NOTE: CONDITION OF OVEN 1.
