• DO NOT operate on a 2-wire extension cord during

repair and use.

• NEVER TOUCH any oven components or wiring during

operation.

• BEFORE TOUCHING any parts of the oven, always

remove the power plug from the outlet.

• For about 30 seconds after the oven stops, an electric

charge remains in the high voltage capacitor. When
replacing or checking, you must discharge the high
voltage capacitor by shorting across the two terminals
with an insulated screwdriver.

•

Remove your watches whenever working close to or

replacing the Magnetron.

• NEVER operate the oven with no load.
• NEVER injure the door seal and front plate of the oven

cavity.

• NEVER put iron tools on the magnetron.
• NEVER put anything into the latch hole and the

interlock switches area.

• Proper operation of the microwave oven requires that

the magnetron be assembled to the waveguide and
cavity. Never operate the magnetron unless it is
properly installed.

2-1

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.

Personnel should not be exposed to the
microwave energy which may radiate from the
magnetron or other microwave generating
device if it is improperly used or connection.
All input and output microwave connections,
waveguide, flange and gasket must be secure
never operate the device without a microwave
energy absorbing load attached.
Never look into an open waveguide or antenna
while the device is energized.
