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. 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. After repairing 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 these 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 microwave leakage test should be carried out. 1 R-1610 R-1611 R-1612 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±5˚C (68˚F) 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-1610 R-1611 R-1612 SERVICE MANUAL OVER THE RANGE MICROWAVE OVEN R-1610/ R-1611/1612 FOREWORD This Manual has been prepared to provide Sharp Electronics Corp.

It must be plugged into a wall receptacle that is properly installed and grounded in accordance with the National Electrical Code and local codes and ordinances. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. WARNING: Improper use of the grounding plug can result in a risk of electric shock. Electrical Requirements The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY CIRCUMSTANCES CUT OR REMOVE THE GROUNDING PIN FROM THE PLUG. The power supply cord and plug must be connected to a separate 120 Volt AC, 60 Hz, 15 Amp. or more dedicated line, using a grounded receptacle. The receptacle should be located inside the cabinet directly above the Microwave Oven/Hood system mounting location. 3-Pronged Plug Grounded Receptacle Box Grounding Pin 3-Pronged Receptacle CONTROL PANEL SENSOR DEFROST TURNTABLE OFF COOK HELP Sensor Cooking Popcorn Fresh vegetables Ground meat Sensor reheat Frozen entrees Baked potatoes Frozen snacks Rice Poultry Custom Help Frozen vegetables Fish/ seafood More from your Microwave Breakfast Bar Super Defrost 1 6 Lunch on the Run Compu Defrost 2 7 3 8 One Dish Dinners Beverage Center 4 9 5 0 Turntable Memory Power Minute On/Off Cook Level Plus Kitchen Timer Stop START Clock Clear Touch On Work Night Fan Auto Light Light Hi/Lo Fan 5 R-1610 R-1611 R-1612 OPERATION DESCRIPTION OF OPERATING SEQUENCE any vapor from the oven cavity and sensor. NOTE: During this first stage, do not open the door or touch STOP/CLEAR pad. 4. When the sensor detects the vapor emitted from the food, the display switches over to the remaining cooking time and the timer counts down to zero. At this time, the door may be opened to stir food, turn it or season, etc. 5. When the timer reaches zero, an audible signal sounds. The shut-off relay and cook relay are de-energized and the power transformer, oven lamp, etc. are turned off. 6. Opening the door or touching the STOP/CLEAR pad, the time of day will reappear on the display and the oven will revert to an OFF condition. SENSOR COOKING CONDITION Using the Sensor Cooking function, the foods are cooked or defrosted without figuring time, power level or quantity. When the oven senses enough steam from the food, it relays the information to its microprocessor which will calculate the remaining cooking time and power level needed for best results. When the food is cooked, water vapor is developed. The sensor “senses” the vapor and its resistance increases gradually. When the resistance reaches the value set according to the menu, supplementary cooking is started. The time of supplementary cooking is determined by experiment with each food category and inputted into the LSI. An example of how sensor works (Baked potato): 1. Potatoes at room temperature. Vapor is emitted very slowly. MIC RO WA VE 2. Heat potatoes. Moisture and humidity is emitted rapidly. You can smell the aroma as it cooks. AH SENSOR MIC RO WA VE 3. Sensor detects moisture and humidity and calculates cooking time and variable power. Cooking Sequence. 1. Touch one of the Sensor Cooking pads. And then touch START/TOUCH ON pad. NOTE: The oven should not be operated on Sensor Cooking immediately after plugging in the unit. Wait two minutes before cooking on Sensor Cooking. 2. The coil of shut-off relays (RY1 and RY3) are energized, the oven lamp, turntable motor and cooling fan motor are turned on, but the power transformer is not turned on. 3. After about 32 seconds, the cook relay (RY2) is energized. The power transformer is turned on, microwave energy is produced and first stage is started. The 32 seconds is the cooling time required to remove 6 R-1610 R-1611 R-1612 MAGNETRON TEMPERATURE FUSE CONTROL UNIT COM. N.O. F1 RY4 RY5 High B3 POWER TRANSFORMER F3 N.C.

One thermistor is housed in the closed vessel filled with dry air while another in the open vessel. Each sensor is provided with the protective cover made of metal mesh to be protected from the external airflow. balance the bridge circuit is deviated to increase the voltage available at AN1 terminal of the LSI. Then the LSI observes that voltage at AN1 terminal and compares it with its initial value, and when the comparison rate reaches the preset value (fixed for each menu to be cooked), the LSI causes the unit to stop sensor cooking; thereafter, the unit goes in the next operation automatically. When the LSI starts to detect the initial voltage at AN1 terminal 16 seconds after the unit has been put in the Sensor Cooking mode, if it is not possible to balance, of the bridge circuit due to disconnection of the absolute humidity sensor, ERROR will appear on the display and the cooking is stopped.

When the unit is set in the sensor cooking mode, 16 seconds clearing cycle occurs than the detector circuit starts to function and the LSI observes the initial voltage available at its AN1 terminal. With this voltage given, the switches SW1 to SW5 in the LSI are turned on in such a way as to change the resistance values in parallel with R98 ~ R102 of IC2. Changing the resistance values results in that there is the same potential at both F-3 terminal of the absolute humidity sensor and AN0 terminal of the LSI. The voltage of AN1 terminal will indicate about -2.5V. This initial balancing is set up about 16 seconds after the unit is put in the Sensor Cooking mode. As the sensor cooking proceeds, the food is heated to generate moisture by which the resistance 13 VA : -15V SW1 P33 P34 P35 P36 P37 0.01uF R95 47k D90 VC : -5V SW2 SW3 SW4 SW5 AN0 LSI (IC1) C92 0.01uF R93 360k R94 10k R90 F-2 R91 3.32k R92 1.8k + IC2 0.015uF F-1 C R96 F-3 3.57k 91 C93 47k Output voltage C 620k R98 C91 (2) Operational Principle of Absolute Humidity Sensor The figure below shows the basic structure of an absolute humidity sensor. A bridge circuit is formed by two thermistors and two resistors (R1 and R2). The output of the bridge circuit is to be amplified by the operational amplifier. Each thermistor is supplied with a current to keep it heated at about 150˚C (302˚F), the resultant heat is dissipated in the air and if the two thermistors are placed in different humidity conditions they show different degrees of heat conductivity leading to a potential difference between them causing an output voltage from the bridge circuit, the intensity of which is increased as the absolute humidity of the air increases. Since the output is very minute, it is amplified by the operational amplifier. 0.1 uF Sensing part (Open vessel) C90 ventilation opening for sensing 92 AN1 R-1610 R-1611 R-1612 COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE WARNING AGAINST HIGH VOLTAGE: Microwave ovens contain circuitry capable of producing very high voltage and current, contact with following parts may result in severe, possibly fatal, electric shock.
