LG VRF Error Codes – Multi V

  Error Codes; Indicate different types of unit failures, assist in self-diagnosis and to track the frequency of occurrence. Error codes are shown on the LED of indoor units, wired remote controller, the outdoor unit control board, and on the main screen of the LG Monitoring View (LGMV) Diagnostic Software. If two or more errors occur simultaneously, the lower error code number is displayed first. After error is resolved, the error code does not display. Error Display; The first, second, and third number on the LED indicates error number; the fourth number on LED indicates outdoor unit number. Examples: 211 = Error No. 21 on master unit, 213 = Error No. 21 on slave2 unit, Error No. 105 on master unit on compressor 1. Error Code Nomenclature Definitions; MICOM: Non-volatile memory chip where unit setup information is stored. EPROM: Non-volatile memory chip where device identification, size, and factory defined default component operating parameters are stored.   LG Multi V Erro...
