MAJOR COMPONENT TESTS

7.1

HV TRANSFORMER

1. Remove lead wire.
2. Measure the resistance of the winding using an ohm meter
3. Primary winding
4. Secondary winding
5. Filament winding
7.2

HV CAPACITOR

1. Remove lead wire
2. Measure the resistance using an ohm meter set to R*1000
3. Terminal to terminal should momentary indicates several ohms but gradually
increases to infinite.
4. Terminal to case should show infinite.
7.3

HV DIODE

1. Remove lead wire.
2. Measure forward resistance, normal diode show continuity.
3. Measure reverse resistance, normal diode show infinite resistance.
7.4

MAGNETRON

1. Remove lead wire.
2. Install the magnetron gasket in the correct position. Check that the gasket is in
good condition.
3. Measure the resistance of the filament terminals. Normal magnetron should
be less than 1 ohm.
4. Measure the resistance between the filament terminal to chassis. Normal
magnetron should be infinite.
7.5

INTERLOCK SWITCH SYSTEM

IMPORTANT: The installation of the interlock and monitor switches is
required by Federal regulations.
