-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 screw driver which is attached to irom plate, and wear rubber gloves when servicing
the high voltage side.
(3) Discharge the high voltage capacitor before touching any oven components or wiring.
1. Check the earthed.
Do not operate on a 2-wire extension cord. The
microwave oven is designed to be used with
earthed.
It is imperative, therefore, to makes sure it is
earthed properly before begining repair work.
2. Warning about the electric charge in the
high voltage capacitor.
For about 30 seconds after the operation
stopped, and 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 vol-tage
capacitor, by using a properly insulated screw
driver to discharge.
(4) When the 15Amp. fuse is blown out due to the operation of the monitor switch; replace primary,
secondary interlock switch and monitor switch.
Refer to next page for the necessary adjustment.
(5) After repair or replacement of parts, make sure that the screws are properly tightened, and all
electrical connections are tightened.
(6) Do not operate without cabinet.
SAFETY PRECAUTIONS FOR DISASSEMBLY AND REPAIR
CAUTION
: Service personnel should remove their watches whenever working close to or repairing
the magnetron.
CAUTION
: When servicing the appliance, need a care of touching or replacing high potential parts
because of electrical shock or exposing microwave. These parts are as follows-H.V.
Transformer, Magnetron, H.V. Capacitor, H.V. Diode.
