Cautions - LG MC-807GLR Service Manual

Unlike other appliances, the microwave oven is
high-voltage and high-current appliance.
Though it is free from danger in ordinary use,
extreme care should be taken during repair.
• 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 stop, an electric
charge remains on the high voltage capacitor. When
replacing or checking, you must discharge the
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 damage the door seal or 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.

CAUTIONS

MICROWAVE RADIATION
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 connected.
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.
• 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.
• Be sure that the magnetron gasket is properly installed
around the dome of the tube whenever installing the
magnetron .
