1. High Voltage Warning
Do not attempt to measureany of the high
voltages--this includes the filament voltage of
the magnetron. High voltage is present during
any cook cycle.
Before touching any components or wiring,
always unplug the oven and discharge the
high voltage capacitor (See Figure here)
2. The high-voltage capacitor remains charged
about 30 seconds after disconnection. Short
the negative terminal of the high-voltage
capacitor to the oven chassis. (Use a
screwdriver.)
3. High voltage is maintained within specified
limits by close-tolerance, safety-related
components and adjustments. If the high
voltage exceeds the specified limits, check
each of the special components.
Precaution
1-2 Special High Voltage Precautions
Note :Touch chassis side first then short to
the high voltage capacitor terminal by
using a screwdriver.
PRECAUTION
There exists HIGH VOLTAGE ELECTRICITY
with high current capabilities in the circuits of
the HIGH VOLTAGE TRANSFORMER
secondary and filament terminals. It is
extremely dangerous to work on or near these
circuits with the oven energized.
DO NOT measure the voltage in the high
voltage circuit including filament voltage of
magnetron.
PRECAUTION
Never touch any circuit wiring with your hand
nor with an insulated tool during operation.
PRECAUTION
Servicemen should remove their watches
whenever working close to or replacing the
magnetron.
