13.Surge Protector

a.) Measure voltage between blue and brown on 

the connecter J

7

Normal

 :AC 207~264V

If normal proceed to b.

Faulty: 

Check if voltage on the fuse 

terminal is AC207~264V

b.) Measure voltage between white and white on 

the J

8

.

Normal:

 AC207~264V.

Faulty:

 replace surge protecter unit.

14.Transformer

Check for the transformer

a.) Measure the voltage between red and red on 

the transmission connector (A

2

).

Normal:

 AC90~110V (12~21 

)

If normal proceed to b.

Faulty:

 Check if the voltage on fuse 

terminals is AC90~110V.

b.) Measure the voltage of the connector (A) on 

the PCB.

Normal: Between 

Brown and Grey AC 

30~50V
Between Yellow and Grey AC 180~220V
If normal, proceed to 

c

Faulty: 

Replace transformer. 

c.) 

Measure voltage between Green and Green 

of connector (D) on PCB.

Normal:

 AC 12~18V

If normal, proceed to 4.

Faulty:

 Replace transformer.

Note)

 The above transformer voltages are meas-

ured while the appliance is in standby mode - 
not while it is operating.
