Refer to page 4-21 for the procedure for ac-
cessing the high-voltage capacitor.
1. Unplug microwave oven or disconnect
power.
2. Discharge the high-voltage capacitor by
touching the leads of a 20,000 Ω resistor
from each of the capacitor leads to chas-
sis ground.
3. Disconnect the wires from one of the
terminals.
4. Set the ohmmeter to the R x 1K scale.
5. Touch the ohmmeter test leads to the ca-
pacitor terminals. The meter should indi-
cate several ohms and gradually return
to infinity.
HIGH-VOLTAGE CAPACITOR
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
WARNING
MAGNETRON
Refer to page 4-21 for the procedure for ac-
cessing the magnetron.
1. Unplug microwave oven or disconnect
power.
2. Disconnect one of the wires from the
magnetron filament terminals.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to the
filament terminals. The meter should in-
dicate less than 1 Ω.
5. Touch one of the ohmmeter test leads to
each of the filament terminals and the other
lead to the chassis. The meter should indi-
cate infinite resistance for both terminals.
