SAFETY PRECAUTIONS FOR DISASSEMBLY AND REPAIR
– Cautions to be observed when trouble shooting.
Unlike many other appliances, the microwave oven is a high-voltage, high-current equipment. It is completely
safety during normal operation. However, carelessness in servicing the oven can result in an electric shock or
possible danger from a short circuit.
You are asked to observe the following precautions carefully.
(1) Always remove the power plug from the outlet before servicing.
(2) Use an insulated screwdriver which is attached to iron plate, and wear rubber gloves when servicing the high
voltage side.
(3) Warning about the electric charge in the high voltage capacitor. When inspecting and repairing the high voltage
side, always short the capacitor terminals and make sure of discharge.
1. Check the grounding.
Do not operate on a 2-wire extension cord.
The microwave oven is designed to be used when
grounded.
It is imperative, therefore, to makes sure it is grounded
properly before before beginning repair work.
2. Warning about the electric charge in the high voltage
capacitor.
For about 30 seconds after the operation stops, electric
charge remains in the high voltage capacitor. When
replacing or checking parts, short between oven chassis
and the negative high terminal of the high voltage
capacitor, by using a properly insulated screw driver to
discharge.
(4) When the 15 Amp. fuse is blown out to operation of the
monitor switch; replace primary, and monitor switch.
Refer to 17~18 page for the necessary adjustment.
(5) After repair or replacement of parts, make sure that the screw are properly tightened, and all electrical
connections are tightened.
(6) Do not operate without cabinet.
CAUTION :
Service personnel should remove their watches whenever working close to or repairing the
magnetron.
WARNING :
When servicing the appliance, need a care of touching or replacing high potential parts
because of electrical shock of exposing microwave. These parts are as follows–H.V.
Transformer, Magnetron, H.V. Capacitor, H.V. Diode.
