Refer to page 2-20 for the procedure for servic-
ing the magnetron.
1.
Disconnect the electrical power to the
microwave oven.
2.
Disconnect the wires from the filament
terminals.
3.
Set the ohmmeter to the R x 1 scale.
4.
Touch the ohmmeter leads to the filament
terminals. The meter should indicate ap-
proximately 0
Ω
.
5.
Set the ohmmeter to the R x 1K scale.
6.
Touch one ohmmeter lead to the filament
terminals, and the other lead to the chas-
sis. The meter should indicate infinity.
MAGNETRON
Filament Terminals
THE HIGH VOLTAGE TRANSFORMER & MAGNETRON
HIGH VOLTAGE TRANSFORMER
Refer to page 2-22 for the procedure for servic-
ing the high voltage transformer.
1.
Disconnect the electrical power to the
microwave oven.
2.
Disconnect the three high voltage trans-
former secondary wires from the high volt-
age capacitor and magnetron.
3.
Disconnect the two wires from the primary
terminals.
4.
Set the ohmmeter to the R x 1 scale.
5.
Touch the ohmmeter leads to the two
primary terminals. The meter should indi-
cate less than 1
Ω
.
6.
Touch the ohmmeter leads to the two
orange/red (filament) wires. The meter
should indicate less than 1
Ω
.
7.
Touch one ohmmeter lead to the light
yellow secondary wire, and the other lead
to the chassis. The meter should indicate
0
Ω
.
8.
Touch one ohmmeter lead to the primary
and filament terminals, and the other lead
to the chassis. The meter should indicate
infinity.
Electrical Shock Hazard
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so could result in death or
electrical shock.
WARNING
