Check Point 3 : Replace Controller PCB
Check Point 2 :
Check Indoor unit electric components
YES
YES
NO
Indoor unit Controller PCB
1. External cause 2. Defective connection of electric components 3. Controller PCB failure
Check Point 1-1 : Reset Power Supply and operate
Does Error indication show again?
Check Point 1-2 :
Check external cause such as noise
Check if the ground connection is proper.
Check if there is any equipment that causes harmonic wave
near the power cable (Neon light bulb or any electronic
equipment which causes harmonic wave).
Note : EEPROM
EEPROM(Electronically Erasable and
Programmable Read Only Memory) is a non-
volatile memory which keeps memorized
information even if power is turned off. It can
change the contents electronically.
To change the contents, it uses higher
voltage than normal, and it can not change a
partial contents. (Rewriting shall be done
upon erasing the all contents.)
There is a limit in a number of rewriting.
Change Controller PCB.
Check all connectors.
(loose connector or incorrect wiring)
Check any shortage or corrosion on PCB.
When power is on and there is some below case.
1. When model information of EEPROM is incorrect.
2. When the access to EEPROM failed.
