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 measureany 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.
2. The high-voltage capacitor remains charged
about 30 seconds after disconnection. Shortthe negative terminal of the high-voltagecapacitor to 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.
