Toshiba Super MMY-MAP0601HT8 - Outdoor Temp Sensor Miscabling; TH Sensor Error

166
Check code name
[F13] / [43]
(d07 / AI-NET)
Check code name
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.

YES
YES
YES
NO
NO
NO
Are installed positions of
TE1 sensor and TL sensor correct?
Are connection of TE1 sensor connector
and TL sensor connector normal?
Are resistance characteristics of
TL sensor and TE1 sensor normal?
Check outdoor I/F P.C. board.
