Indicator Indoor unit
Operation indicator 6 time flash
Timer indicator 2 time flash
Economy indicator Continuous flash
Error code E: 62
Detective actuator Outdoor unit main 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.
Forecast of cause
External cause
Defective connection of electrical components
Main PCB failure
Check point 1. Reset power supply and operate
Does error indication show again?
→ If no, go to "Check point 1-2".
↓
Check point 2. Check Indoor unit electrical components
• Check all connectors. (loose connector or incorrect wiring)
• Check any shortage or corrosion on PCB.
↓
Check point 3. Replace the main PCB
If Check Point 1,2 do not improve the symptom, replace the main PCB.
↓
End
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).
↓
End
NOTE:
EEPROM
EEPROM (Electronically Erasable and Programmable Read Only Memory) is a non-volatile
memory which keeps memorized information even if the power is turned off. It can change
the contents electronically. To change the contents, it uses higher voltage than normal, and
it cannot change a partial contents. (Rewriting shall be done upon erasing the all contents.)
There is a limit in a number of rewriting.
