FAN MOTOR

Measure the resistance.

Normal:

 

(Wire leads removed)

(Ohm-meter scale: R x 1)

A:Approx. 85

~ 100 ohm.

 

 

B:Approx. 10

~ 25 ohm.

 

 

Abnormal: Infinite or several

 

 

ohm.

TURNTABLE MOTOR

(Wire leads removed)

Measure the resistance. (Ohm-meter scale: R x 1)

Normal: Approx. 100 ~ 150 ohm

Abnormal: Infinite or several ohm.

NOTE : • A MICROWAVE LEAKAGE TEST MUST ALWAYS BE PERFORMED WHEN THE UNIT IS SERVICED FOR ANY REASON.

MAKE SURE THE WIRE LEADS ARE IN THE CORRECT POSITION.

WHEN REMOVING THE WIRE LEADS FROM THE PARTS, BE SURE TO GRASP THE CONNECTOR, NOT THE WIRES.
