SMART DIAGNOSIS™
ENGLISH
SMART DIAGNOSIS
Should you experience any problems with your oven, 
it has the capability of transmitting data to your smart 
phone using the LG Smart ThinQ Application or via your 
telephone to the LG call center.
Smart Diagnosis™ cannot be activated unless your oven 
is turned on by pressing the Power button. If your oven 
is unable to turn on, then troubleshooting must be done 
without using Smart Diagnosis™.

SMART DIAGNOSIS™ USING YOUR 
SMART PHONE
1.  Download the LG Smart ThinQ application on your 
smart phone.
2.  Open the LG Smart ThinQ application on your smart 
phone. Press Smart Diagnosis™ button to advance to 
the next screen.
3.  Follow directions of the application. Using ‘Tag on’ 
is recommended but, if it does not work well, the 
application will show how to use Audible Diagnosis.

 ] in the LG Smart ThinQ app for a more

Call quality differences by region may affect the 
function.

Use the home telephone for better communication 
performance, resulting in better service.
y
Bad call quality may result in poor data transmission 
from your phone to the machine, which could cause 
Smart Diagnosis™ to malfunction.
NOTE
y
For best results, do not move the phone while the 
tones are being transmitted.

If the call center agent is not able to get an accurate 
recording of the data, you may be asked to try again.
SMART DIAGNOSIS™ THROUGH THE 
CALL CENTER
1.  Call the LG call center at: (LG U.S.) 1-800-243-0000 
(LG Canada) 1-888-542-2623.
2.  When instructed to do so by the call center agent, 
hold the mouthpiece of your phone over the Smart 
Diagnosis™ logo on the machine. Hold the phone 
no more than one inch from (but not touching) the 
machine.
3.  Touch and hold the Start button for three seconds.
4.  Keep the phone in place until the tone transmission 
has nished. This takes about 6 seconds and the 
display will count down the time.
5.  Once the countdown is over and the tones have 
stopped, resume your conversation with the call 
center agent, who will then be able to assist you in 
using the information transmitted for analysis.
Do not touch any other buttons or icons on the dis-
play screen.
