Lg Electronics LFX25974ST Manual De Usuario

Should you experience any problems with your refrigerator, 
it has the capability of transmitting data via your telephone to 
the LG service center. This gives you the capability of speak-
ing directly to our trained specialists. The specialist records 
the data transmitted from your machine and uses it to ana-
lyze the issue, providing a fast and effective diagnosis.

If you experience problems with your refrigerator, call 
1-800-243-0000. Only use the Smart Diagnosis feature when 
instructed to do so by the LG call center agent. The transmis-
sion sounds that you will hear are normal and sound similar 
to a fax machine.

Smart Diagnosis cannot be activated unless your refrigerator 
is connected to power. If your refrigerator is unable to turn 
on, then troubleshooting must be done without using Smart 
Diagnosis. 

First, call 1-800-243-0000. Only use the Smart Diagnosis 
feature when instructed to do so by the LG call center agent.

1

  Lock the display. To lock the display, press and hold the 

Lock button for three seconds. (If the display has been 
locked for over five minutes, you must deactivate the lock 
and then reactivate it.)

2

  Open the right refrigerator door.

3

  Hold the mouthpiece of your phone in front of the speak-

er that is located on the right hinge of the refrigerator 
door, when instructed to do so by the call center.

4

  Press and hold the Freezer Temperature button for three 

seconds while continuing to hold your phone to the 
speaker.

5

  After you hear three beeps, release the Freezer Tempera-

ture button.

6

  Keep the phone in place until the tone transmission has 

finished. This takes about 15 seconds, and the display will 
count down the time. Once the countdown is over and 
the tones have stopped, resume your conversation with 
the specialist, who will then be able to assist you in using 
the information transmitted for analysis. 

For best results, do not move the phone while the 

 

y

tones are being transmitted.
If the call center agent is not able to get an accurate 

 

y

recording of the data, you may be asked to try again.
