RELAY

Check for continuity of relay with an

Normal: Approx.

 

ohm-meter.

 

ON: 0 ohm

 

(Remove lead wires from relay and

 

OFF:

ohms

 

operate the unit.)

 

Abnormal: Infinite or several

 

 

 

 

 

 

 

 

 

 

 

ohms.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Relay 2

FAN MOTOR

Measure the resistance.

 

Normal: Approx. 50 ~ 150 ohms

(Wire leads removed)

(Ohm-meter scale: R x 100)

 

 

Abnormal: Infinite or several

 

 

 

 

B(BK)

 

ohms.

 

A(RD)

 

 

 

C(WH)

 

 

 

 

 

 

TURNTABLE MOTOR

(Wire leads removed)

Measure the resistance. (Ohm-meter scale: R x 1000)

Normal: Approx. 2 ~ 4K ohms

Abnormal: Infinite or several ohms.

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.
