TH sensor error
Cause of operation
IGBT built-in sensor error in A3-IPDU
Sub-code:
01: Compressor 1 side 02: Compressor 2 side
This error code means IGBT built-in temperature sensor error.
Check connection of connectors CN06 on IPDU P.C. board and CN600 on I/F P.C. board.
If sensor is normal, replace IPDU P.C. board.
