- 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 carafully.
(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 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 each terminal of the
high voltage capacitor, by using a properly insulated
screw driver to discharge.
(4) When the 15 Amp. fuse is blown out due to operation of the monitor switch; replace primary, and monitor switch.
Refer to 24 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.
