SERVICE MANUAL SUPPLEMENT  
for Model EM-S85M  
Microwave Oven  
CAUTION  
WARNING TO SERVICE TECHNICIANS  
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)(i) A microwave leakage check to verify compliance with the Federal performance standard should be  
performed on each oven prior to release to the owner. (For U.S.A)  
(e)(ii) A microwave leakage check to verify compliance with the Canadian Regulation, HEALTH AND WELFARE,  
SOR/79-920 should be performed on each oven prior to release to the owner. (For CANADA)

A. SINCE NEARLY 2,000 VOLTS EXISTS IN SOME  
CIRCUITS OF THIS MICROWAVE OVEN, REPAIRS SHOULD  
BE CARRIED OUT WITH GREAT CARE.  
B. TO AVOID POSSIBLE EXPOSURE TO MICROWAVE ENEGY  
LEAKAGE, THE FOLLOWING PRECAUTIONS MUST BE  
TAKEN BEFORE SERVICING.  
Thermal Protector open  
(1)  
(a)  
Before the power is applied :  
at 122oC for Magnetron  
Open and close door several times to make sure the prima-  
ry interlock switch, the interlock monitor switch and the door  
sensing switch operate properly. (Listen for the clicking  
sound from the switches.) Make sure the interlock monitor  
switch closes after the primary interlock switch is opens  
when the door is opened.

(2)  
(a)  
After the power is applied :  
Open and close the door to see if the interlock mechanism  
operates properly.  
(b)  
(3)  
Check microwave energy leakage with a leakage detector  
and confirm the energy leakage is below 5 mW/cm2.  
Do not operate the unit until it is completely repaired, if any  
of the following conditions exists:  
3. POWER OUTPUT MEASUREMENT  
(a)  
(b)  
(c)  
(d)  
NOTE  
Door does not close firmly against the cavity front.  
The hinge is broken.  
The power output specification, 850 W on this model is  
measured with IEC measurement. The power output is  
measured with two (2) liters water is equivalent  
to 850 W in measurement with IEC, when measured with  
the following power output.  
The choke dielectric or the door seal is damaged.  
The door is bent or warped, or there is any other visible dam-  
age to the oven that may cause microwave energy leakage.  
NOTE : Always keep the seal clean.  
(e)  
Make sure there are no defective parts in the microwave  
generating and transmission assembly. (especially wave-  
guide).  
(A) 1.Fill two beakers with one liter of tap water respectively  
2.Use accurate thermometer and measure each water  
temperature respectively.  
(4)  
(a)  
(b)  
(c)  
(d)  
(e)  
The following items should be checked after the unit is  
repaired :  
(B) Place beakers side by side in the centre of the glass tray.  
The interlock monitor switch is connected correctly and firm-  
ly.  
(C) 1.Set the timer at any position more than 2 minutes.  
2.Heat the water correctly for 2 minutes.  
The magnetron gasket on the magnetron is properly posi-  
tioned.  
(D)  
(E)  
Take the beakers out, immediately stir the water and mea-  
sure the water temperature respectively.  
Waveguide and oven cavity are intact (no leakage of  
microwave energy).  
1.Calculate the temperature rise of water in each beaker.  
2.Then calculate the average value of two temperature  
rises.  
The door can be properly closed and the safety switches  
work properly.  
3.Output power can be calculated by the equation;  
Power Output (W) = 70 x Dt  
Where Dt is an average temperature rise in degrees  
Centigrade.  
The oven must be stopped when the door is opened or the  
time is up.  
(F)  
Power Output shall be in the following range :  
AverageTemperature Rise Power Output  
The oven must not be operated with any of the  
above components removed or bypassed.  
Minimum  
Maximum  
9.9oC  
693W  
889W  
12.7oC  
(G)  
Power Output is affected by the line voltage under load.  
For correct Power Output measurement, the line voltage  
under load must be 120± 2volts.
