SMART DIAGNOSIS
ENGLISH
3
  Hold the mouthpiece of your phone in 
front of the speaker 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 button for three 
seconds while continuing to hold your 
phone to the speaker. 
5
  After you hear three beeps, release the 
Freezer 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. 
Should you experience any problems with your 
refrigerator, it has the capability of transmitting 
data via your telephone to the LG service 
center. This allows you to speak directly to our 
trained specialists. The specialist records the 
data transmitted from your machine and uses 
it to analyze 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 
transmission 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™. 
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.

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.)

SMART DIAGNOSIS
 NOTE
For best results, do not move the phone  
y
while the tones are being transmitted.
If the call center agent is not able to get  
y
an accurate recording of the data, you 
may be asked to try again.
 NOTE
Call quality differences by region may  
y
affect the function.
Use the home telephone for better  
y
communication performance, resulting 
in better service.
Bad call quality may result in poor data  
y
transmission from your phone to the 
machine, which could cause Smart 
Diagnosis™ to malfunction.
