MAJOR COMPONENT TESTS
HV TRANSFORMER
Remove lead wire.
Measure the resistance of the winding using an ohmmeter
Primary winding
3 ohm (approx.)
Secondary winding
100 ohm (approx.)
Filament winding
0 ohm (approx.)
HV CAPACITOR
Remove lead wire
Measure the resistance using an ohmmeter set to R*1000
Terminal to terminal should momentary indicates several ohms but gradually increases to
infinity.
Terminal to case should show infinity.
HV DIODE
Remove lead wire.
Measure forward resistance, normal diode show continuity.
Measure reverse resistance, normal diode show infinite resistance.
MAGNETRON
Remove lead wire.
Install the magnetron gasket in the correct position. Check that the gasket is in good condition.
Measure the resistance of the filament terminals. Normal magnetron should be less than 1
ohm.
Measure the resistance between the filament terminal to chassis. Normal magnetron should be
infinity.
