Trouble shooting 9
INDOOR UNIT Error Method:
Indicate or Display:
Indicate or Display:
Refer to error code table.
Indoor EEPROM abnormal
(Model No.)
Indoor Unit Control PCB (AS,AR),
Main PCB (AU) circuit
1. External cause 2. Defective connection of electric components 3. Control PCB failure (AS,AR),
Main PCB (AU)
Check Point 1-1 : Reset Power Supply and operate
Does Error indication show again?
Check Point 1-2 :
Check external cause at Indoor and Outdoor
(Voltage drop or Noise)
Instant drop : Check if there is a large load electric apparatus
in the same circuit.
Momentary power failure : Check if there is a defective contact
or leak current in the power supply
circuit.
Noise : Check if there is any equipment causing harmonic
wave near electric line.(Neon bulb or electric
equipment that may cause harmonic wave)
Check the complete insulation of grounding.
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 Control PCB (AS,AR), Main PCB (AU).
Check all connectors.
(loose connector or incorrect wiring)
Check any shortage or corrosion on PCB.
When the model information being read from EEPROM has
an apparent error.
