LG LB-H0850QC Air Conditioner
Frequently Asked Questions (10)
What should I do if the remote controller display shows 'CH'?
'CH' flashing in the remote controller display indicates that a problem has occurred with the air conditioner. You should contact your dealer for assistance when this self-diagnosis code appears.
How often should I clean the air filter on the LB-H0850QC?
The air filters should be checked and cleaned once every 2 weeks, or more often if necessary. Clogged air filters reduce airflow, lower cooling and dehumidifying effects, and can waste up to 6% of the electricity used to operate the air conditioner.
How do I properly clean the air filter?
Clean the filter with a vacuum or warm, soapy water. If very dirty, wash with a solution of detergent in lukewarm water, but do not use hot water of 50°C or more as it may deform the filter. After washing, dry the filter well in the shade before re-installing it.
Why does the air conditioner not start immediately when restarted?
The air conditioner will not operate for about 3 minutes when restarted — this is a built-in protector for the mechanism. Simply wait about three minutes and operation will begin.
How do I activate the Child Lock function on the remote controller?
Press the Timer button and Minute Set button simultaneously for three seconds to activate Child Lock mode. The display will show 'CL', and pressing any other button will not change the mode while Child Lock is active. To cancel Child Lock, press the same two buttons again for three seconds.

What should I do before leaving the air conditioner unused for a long period of time?
Before extended periods of non-use, operate the air conditioner in Air Circulation mode for 2 to 3 hours to dry out the internal parts. Then turn off the circuit breaker, as dirt may collect inside the unit and could cause a fire.
Is it safe to clean the air conditioner with water?
Do not clean the air conditioner with water, as water may enter the unit and degrade the insulation, which could cause electric shock. For the grille, case, and remote control, wipe with a soft, dry cloth only, and do not use bleach or abrasives.
Why is there a cracking sound coming from the air conditioner during operation?
A cracking sound is generated by the expansion and contraction of the inlet grille and other parts due to changes in temperature. This is a normal occurrence and does not indicate a malfunction.
What could cause the air conditioner to not cool effectively?
Possible causes include a dirty air filter, an incorrect temperature setting, or blocked air inlet or outlet vents on the indoor unit. The room may also have been very hot when the unit was first turned on, so allow time for it to cool down.
Can installation and repair of the LB-H0850QC be done by the customer?
No, installation, removal, and reinstallation must not be done by the customer, as improper installation can cause water leakage, electrical shock, or fire. Repair or relocation should also not be performed by the customer; an authorized service technician must be contacted for all such work.
