Servicing Requirements
1.1
Health & Safety
Note: When servicing the oven, health and safety issues must be considered at all times. Specific safety issues are listed below with their appropriate icon. These are
illustrated throughout the service information to remind service people of the health and safety issues
1.1.1 Electrical Safet
y
WARNING! TO AVOID ELECTRIC SHOCK!
Do not attempt to service this oven without suitable training and qualifications.
Unlike other appliances, the microwave oven is high-voltage and high-current equipment.
Though it is free from danger in ordinary use, extreme care should be taken during repair.
BEFORE TOUCHING any parts of the oven, always remove the power plug from the outlet.
For about 60 seconds after the oven stops, an electric charge remains in the high voltage capacitor. When replacing or checking, you must wait to permit
the capacitor discarding.
Ensure the main power has been disconnected before servicing any part of the oven. If the power is required to be on for electrical fault finding, then
extreme care should be taken not to make contact with electrical components other than with testing probes.
Ensure the oven is turned off when removing any electrical component or connection.
1.1.
2
Good Working Practices
Ensure the work areas are kept tidy and free of hazards while servicing the oven. On completion of the servicing, ensure the oven and work areas are left
clean and tidy.
1.1.
3
Insulation Test
Megger test to check insulation.
1.1.
4
Sheet Metal Edges
When working around cut sheet metal edges use appropriate gloves or protection to eliminate the chance of receiving a laceration.
1.1.5 Microwave emissions
Precautions to be observed before and during servicing to avoid possible exposure to excessive microwave energy. On every service call. A check for
microwave energy emission must be made. 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 centimeters (about 2 inches) or more from the external surface of the oven.
21 CFR 1030.10, Performance Standard for Microwave Ovens.

Servicing Requirements
1.2
Measurement of energy emission
CAUTION
For microwave energy emission On every service call. A check for microwave energy emission must be made according to the following
manner.
1.2.1 Measurement of energy emission
Measurement must be made with the microwave oven operating at its maximum output and containing a load of 275±15 milliliters of tap water initially at
20°±5° Celsius (68±9°F) placed within the cavity at the center.
NOTE: The water container must be a 600 milliliter beaker and made of an electrically none conductive material such as glass or plastic. The cook tray
must be in place when measuring emission.
A properly operating door and seal assembly will normally register emission no greater than 5 mW/cm2 to allow for measurement uncertainty with the
cooking shelf or tray in place.
1.2.
2
All repairs must be performed in such a manner that microwave energy emission is minimal.
Follow the instructions supplied with the detector being used and perform an R.F. emission test around the door front,
and all edges and vent of the outer case. The cabinet (wrapper) must be in place and the oven fully assembled. When
performing an emission survey, with the meter on FAST RESPONSE, the movement of the detector probe shall not
exceed one (1) inch per second.
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 centimeters (about 2 inches) or more from the external surface of the
oven.
All microwave ovens exceeding the emission level of 4 mW/cm2 must be reported to Dept. of Service for microwave
ovens and the manufacturer immediately. 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 properly and the door
interlock switch fails, the fuse will blow. If this happens, all interlock switches must be replaced. The contacts of the
interlock switches ma
y
be welded to
g
ether.

Safety Thermostats
This appliance is built with three bi-metal mechanical thermostats. The thermostats are mounted in contact with the metal sheet .
The function of the safety thermostat is to protect the of the oven from overheating in the event of a malfunction of the cooling fan.
In the event that the temperature is rising over the limits, the thermostat will switch mechanically from off position to on position and all of the heating
elements will be cut off from the power. All of the electronics will be still powered.
The reset is automatic when the cooling fan was replaced or the cooling fan problem was solved and the temperature is in the right functioning parameters.
