What does indoor unit heat exchanger sensor (TCJ) error mean on Toshiba Air Conditioner?
- RRicardo CampbellSep 14, 2025
If your Toshiba Air Conditioner displays an indoor unit heat exchanger sensor (TCJ) error, it means an open-circuit or short-circuit of the heat exchanger sensor (TCJ) was detected. This is related to the Heat exchanger sensor (TCJ) or the indoor P.C. board and you should perform an auto-reset.
