NOTE: When testing the magnetron, be sure to install the magnetron gasket

 

in the correct position and be sure that the gasket is in good condition.

HIGH VOLTAGE

Measure the resistance.

Normal: Momentarily indicates

(Ohm-meter scale: Rx1000)

several ohms, and

 

¥ Terminal to terminal.

then gradually returns

 

 

to infinite.

Measure the resistance.

Normal: Infinite.

(Ohm-meter scale: Rx1000)

 

¥ Terminal to case.

 

HIGH VOLTAGE

Measure the continuity (Forward).

Normal: Continuity.

DIODE

Abnormal: Infinite.

 

NOTE :

 

 

Some inexpensive meters

 

 

may indicate infinite

 

 

resistance in both direction.

Measure the continuity (Reverse).

Normal: Infinite.
