Cautions - LG LTRM1240SW Service Manual

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.
• 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.
• DO NOT touch any parts of the control panel circuit. A
resulting static electric discharge may damage this P.C.B.
• 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.

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 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.
• 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.
