17. When checking the continuity of the witches
or transformer, always make sure that thepower is OFF, and one of the lead wires isdisconnected.
18. Components that are critical for safety are
indicated in the circuit diagram byshading,
or .
19. Use replacement components that have the
same ratings, especially for flame resistanceand dielectric strength specifications. Areplacement part that does not have thesame safety characteristics as the originalmight create shock, fire or other hazards.
1. High Voltage Warning
Do not attempt to measure any of the highvoltages--this includes the filament voltageof the magnetron. High voltage is presentduring any cook cycle.
Before touching any components or wiring,always unplug the oven and discharge thehigh voltage capacitor (See Figure 1-1)
2. The high-voltage capacitor remains charged
about 30 seconds after disconnection. Shortthe negative terminal of the high-voltagecapacitor to the oven chassis. (Use ascrewdriver.)
3. High voltage is maintained within specified
limits by close-tolerance, safety-relatedcomponents and adjustments. If the highvoltage exceeds the specified limits, checkeach of the special components.

1-2 Special Servicing Precautions (Continued)
1-3 Special High Voltage Precautions
Servicemen should remove their watches wheneverworking close to or replacing the magnetron.
There exists HIGH VOLTAGE ELECTRICITY with highcurrent capabilities in the circuits of the HIGH VOLTAGETRANSFORMER secondary and filament terminals. It isextremely dangerous to work on or near these circuitswith the oven energized.DO NOT measure the voltage in the high voltage circuitincluding filament voltage of magnetron.
Never touch any circuit wiring with your hand nor withuninsulated tool during operation.

Touch chassis ground first then short to the highvoltage capacitor terminal by using screwdriver orjumper wire.
