Smart Diagnosis™ Using a Smart 
Phone
 • For appliances with the   or   logo
Use this function if you need an accurate 
diagnosis by an LG Electronics customer 
information centre when the appliance 
malfunctions or fails.
Smart Diagnosis™ can not be activated unless 
the appliance is connected to power. If the 
appliance is unable to turn on, then 
troubleshooting must be done without using 
Smart Diagnosis™.
NOTE
 • Be sure to keep ambient noise to a minimum 
or the phone may not correctly receive the 
buzzer beeps from the indoor unit.
