WARNING TO SERVICE PERSONNEL

Microwave ovens contain circuitry capable of producing very high voltage and current. Con- tact 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

Before Servicing

1, Disconnect the power supply cord and then remove outer case cabinet.

2. Open the door and block it open. 3. Discharge the high voltage capacitor.

WAl?NING:RISK OF ELECTRICAL SHOCK. DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE SERVICING. The high-voltage capacitor remains charged about 60 se- conds after the oven has been switched off. Wait for 60 se- conds and then short-circuit the connection of the high volt- age capacitor (that is the connecting lead of the high voltage rectifier) against the chassis with the use of an insulated screwdriver.

Whenever troubleshooting is performed, the powersup- ply must be disconnected. In some cases it may be nec- essary to connect the power supply after the outer case has been removed, in this event:

6.

Disconnect the power supply cord and then remove outer case cabinet. Open the door and block it open. Discharge the high voltage capacitor. Disconnect the leads to the primary of the power transformer. Ensure that the leads remain isolated from other components and oven chassis by using insulation tape. After the above procedure, reconnect the power sup- ply cord.

Reconnect all Lads removed from components dur- ing testing. Re-install the outer case (cabinet). Reconnect the power supply cord after the outer case is installed. Reconnect the power supply cord after the outer case is installed. Run the oven and check all functions.

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 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 to see if the wa- ter is hot. If the water remains cold, carry out Before Servicing procedure and re-examine the connection 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 the microwave leakage test should be car- ried out.

MICROWAVE MEASUREMENT

R-l 85OA

;:;gs PROCEDURE

After adjustment of the door, interlock and monitor switches are completed individually or collectively, a IN- TERLOCK SWITCH TEST and MICROWAVE LEAK- AGE TEST must be performed to assure compliance with DHHS (CDRH) Performance Standards for Micro- wave Ovens.

Interlock Switch Test

Make sure that the door sensing switch, secondary in- terlock switch and monitor switch are operating properly by checking with an ohmmeter. Refer to the “Test Procedure” of the door sensing switch, secondary interlock switch and monitor switch.

Microwave Leakage Test

Requirements

1. Microwave leakage limit (Power density limit). The power density of microwave radiation emitted by a microwave oven shall not exceed 1 mW/cm* at any point 5cm or more from the external surface of the oven, measured prior to acquisition-by the purchaser, and thereafter (through the useful life of the oven) 5mW/cm* at any point 5cm or more from the external surface of the oven.

2. Safety interlock switches. Primary interlock relay and door sensing switch will prevent microwave radiation emissions in excess of the requirement as above mentioned, secondary interlock switch shall prevent microwave radiation emission in excess of 5 mW/cm* at any point 5cm or more from the external surface of the oven.

Preparation For Testing

Before beginning the actual measurement of leakage, proceed as follows:

1. Make sure that the actual instrument is operating nor- mally as specified in its instruction booklet.

Note: Survey instruments that comply with the require- ment for instrumentatoin 21 CFR1030.1 O(c)(3)(i), as prescribed by the performance standard for microwave ovens must be used for testing.

2. Place the oven tray in the oven cavity.

3. Place the load of 275 & 15ml(9.8 oz.) of tap water ini-

tially at 20 z!z 5OC (68OF) in the center of the oven cav- ity. The water container shall be a low form of 600 ml (20 oz.) beaker with an inside diameter of approximately 8.5 cm (3 % in.) and made of an electrically noncon- ductive material such as glass or plastic. The placing of this standard load in the oven is impor- tant 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 put the oven into a cook cycle for several minutes. If the water begins to boil before the survey is completed, replace it with 275ml of cool wa- ter.

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 lin./sec (2.5cm/sec.) along the gap, watching for the maxi- mum indication of the meter.

3. Check for leakage at the door screen, sheet metal seams and other accessible positions where the con- tinuity of the metal has been breached (eg., around 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 per- mitted by the closed latch assembly.

4. Measure carefully at the point of the highest leakage and make sure that the highest leakage is no greater than 4 mW/cm* to allow for measurement uncertainty, 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.
