RESULTS

1)

Measure the resistance: Across the

filament terminals of the magnetron

Normal reading:

with an ohm-meter on Rx1 scale.

Less than 1 ohm.

2)

Measure the resistance: Between

Normal reading:

MAGNETRON

Infinite ohms.

(Wire leads are

with an ohm-mater on high test scale.

NOTE: Replace the magnetron, if the

magnetron checks and all of the

high voltage component tests are

good, but the unit still does not heat

a load.
