Unlike many other appliances, the microwave oven is a high
voltage, high current apparatus.
Although it is safe to operate, extreme care should be taken
during repair.
CAUTION
Servicemen should remove their watches and rings whenever working
close to or replacing the magnetron.
7.1. Check the earthing/grounding
Do not operate on a 2 wire extension cord. The microwave
oven is designed to be used in a completely earthed/grounded
condition. It is imperative, therefore, to make sure it is properly
earthed/grounded before beginning repair work.
7.2. Warning about the electric
charge in the high voltage
capacitor.
For about 30 seconds after the oven is turned off, an electric
charge remains in the high voltage capacitor. When replacing
or checking parts, remove the power plug from the outlet and
short the terminal of the high voltage capacitor (terminal of lead
wire from diode) to chassis ground with and insulated handle
screwdriver or insulated jumper lead wire to discharge.
WARNING
There is high-voltage present, with high-current capabilities in the
circuits of the high voltage winding and filament winding of the high
voltage transformer. It is extremely dangerous to work on or near these
circuits with the oven energized.
DO NOT measure the voltage in the high voltage circuit including
filament voltage of magnetron.
WARNING
Never touch any circuit wiring with your hand nor with an insulated tool
during operation.
7.3. If the door lock, the door
switch, the door seal or the
door develops a malfunction,
be sure not to operate the
oven until complete repairs
are made.
If the oven is operated with any of these parts in imperfect
condition, hazardous microwave leakage might occur.
WARNING
Never operate the oven until the following are confirmed:
(A) The door is tightly closed.
(B) There is no broken hinge or door arm.
(C) The door seal is not damagd.
(D) The door is not bent or warped.
(E) There is no other visible damage.
