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 per formance standard should be performed

on each oven prior to release to the owner.

In the area emitting the highest reading, switch the meter to SLOW RESPONSE, and take a reading for minimum of three (3) seconds. We recommended the pattern outline shown below when the door surface is surveyed.

NOTE : Periodically check to be sure that the probe tip is

not worn or dirty.

The following U.S. standard applies to microwave ovens : 21 CFR 1030.10, Performance Standard for Microwave Ovens.

It requires that the power density of the microwave radiation emitted by a microwave oven shall not exceed five (5) milliwatts per square centimeter at any point 5 centimeter (about 2 inches) or more from the external surface of the oven.

All microwave ovens exceeding the emission level of 4mW/cm microwave ovens and the manufacturer immediately and the owner should be told not to use the microwave oven until it has been repaired completely.

If a microwave oven is found to operate with the door open, report to Dept. of Service, the manufacturer and CDRH* immediately. Also tell the owner not to use the oven. *CDRH : Center for Device and Radiological Health.

The interlock monitor switch acts as the final safety switch protecting the customer from microwave radiation. If the interlock monitor switch operates to blow the fuse with interlocks failed, you must replace all interlock switches primary and secondary interlock switches and the monitor switch with new ones because the contacts of those interlock switches may be melted and welded together.

(1) Loosen 2 screws securing the lever stopper. (2) Adjust the lever stopper position so that it is pushed

forward and pull backward until there is about zero gap between the latch lever and the switch body on the primary interlock switch and at the same time there is about zero gap between the door latch and the switch body on the door sensing switch when

the door latch is securely locked. (3) Tighten the lever stopper screws securely. (4) Make sure the interlock monitor switch closes after

the primary interlock switch opens when the door

is opened very slowly, according to “CHECKOUT

PROCEDURE FOR SWITCHES” on page 6. (5) Make sure the interlock monitor switch opens before

the primary interlock switch closes when the door is

closed very slowly, according to “CHECKOUT

PROCEDURE FOR SWITCHES” on page 6. (6) Make sure the microwave energy leakage should be

no greater than 4mW/cm2 to allow for measurement

uncertainty when measured with a detector.

(All service adjustments must be made for

minimum microwave energy leakage readings.)

The power output specification, 1050W. on this model is measured with IEC measurement. The power output is measured with two (2) liters water is equivalent to 1050W. in measurement with IEC, when measured with the following power output.

(1) Fill two beakers (glass or plastic) with each one liter of

tap water (about 20°C) and measure the water temperature. (Use a thermometer with a 1/10 degree gauge).

(2) Place the beakers side by side in the centre of the glass tray.

(3) Close the door, set the “TIME” for two minutes. (“200” in

the display window). Touch the “START” key and heat the water exactly for two minutes.

(4) Take the beakers out, immediately stir the water and

measure the water temperature respectively.

(5) Calculate the temperature rise of water in each beaker.

Then calculate the average value of two temperature rises. Output power can be calculated by the equation : Power Output (W) = 70 x ∆t Where ∆t is an average temperature rise in degrees Centigrade.

(6) Power Output shall be in the following range :

Minimum 19.6°F (10.9°C) 763W Maximum 20.0°F (14.0°C) 980W

(7) Power Output is affected by the line voltage under load.

For correct Power Output measurement, the line voltage under load must be 120±1 volts.

(1) Disconnect all wire leads from primary interlock and

Interlock monitor switch.

(2) Pull the primary interlock switch or Interlock monitor

switch upward at the same time while pushing the switch stoppers to allow a space between the switch body and catches.

(3) Make necessary adjustments or replacement of

switch by the reversing step (2) and check microwave energy leakage according to “1. ADJUSTMENT PROCEDURES” on page 1, after it is replaced with new one, and check proper operation of it according to “CHECKOUT PROCEDURE FOR SWITCHES” on page 6.

(4) Remove 4 screws securing the magnetron to the

waveguide.

(5) Take out Magnetron VERY CAREFULLY.

1. When removing the magnetron from the cavity or wave guide, use a proper care so that the dome of the magnetron does not hit any adjacent parts of microwave oven.

2. Make sure that the contact face of the magnetron gasket is free from any damage or deformation.

3. Adjust the position of the magnetron properly, so that it correctly sits in place and the magnetron gasket is in contact with the mounting rim evenly.

4. While holding the magnetron under this condition, tighten mounting screws or nuts with your fingers temporarily.

5. Further tighten the screws or nuts with a box wrench, giving one or two turns to each of the screws (or nuts) alternatively so that the magnetron is mounted on to the bracket uniformly.

Remove the 20A fuse with a screwdriver.

-- When replacing the 20A fuse, be sure to use an exact repair part.

-- If the 20A fuse blows immediately, check the primary interlock switch, the relay 2 (on the control circuit board) and the interlock monitor switch according to,
