20A LINE FUSE
Refer to page 4-10 for the procedure for ac-
cessing the line fuse.
1. Unplug microwave oven or disconnect
power.
2. Set the ohmmeter to the R x 1 scale.
3. Touch the ohmmeter test leads to the
ends of the fuse. The meter should indi-
cate a closed circuit (0 Ω).
WARNING
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.
LINE FILTER CAPACITOR
Refer to page 4-10 for the procedure for ac-
cessing the line filter capacitor.
1. Unplug microwave oven or disconnect
power.
2. Discharge the line filter and high volt-
age capacitors using a 20,000 Ω resis-
tor from the terminals to chassis
ground.
3. Disconnect the wire connectors from the
line filter capacitor terminals.
4. Set the ohmmeter to the R x 1K scale.
5. Touch the ohmmeter test leads to the
capacitor terminals and ground. The meter
should indicate several ohms, and gradu-
ally return to infinity.
