In brief
Fault code 0d on Toshiba Seiya / Shorai means: Fault code 0d indicates a problem with the temperature sensor clipped onto the indoor unit heat exchanger (TC sensor). It is used for cooling and overheating management. Most common cause: TC sensor dislodged from its housing, cut, or incorrect resistance. First action: Disconnect the TC sensor (red or white connector depending on model).. Call a registered engineer if the fault returns after basic checks or involves refrigerant work (F-Gas registered engineer required).
According to the Toshiba Service Manual, the TC sensor standard resistance is 10 kΩ at 25°C.

What does fault code 0d on Toshiba mean?
Fault code 0d indicates a problem with the temperature sensor clipped onto the indoor unit heat exchanger (TC sensor). It is used for cooling and overheating management.
TC sensor dislodged from its housing, cut, or incorrect resistance.
Symptoms
- Possible icing of the indoor unit
- Irregular operation
- Shutdown on fault
Diagnosis
1. Sensor measurement
- Disconnect the TC sensor (red or white connector depending on model).
- Measure the resistance (Standard 10 kΩ at 25°C).
How to reset fault code 0d on Toshiba?
Reclip the sensor if it is hanging loose. Replace it if its resistance value is infinite or zero.
When should you call an F-Gas engineer?
Fault code 0d most often appears during air conditioning operation, particularly on Seiya / Shorai models. Possible icing of the indoor unit.
Field context
Fault code 0d most often appears during air conditioning operation, particularly on Seiya / Shorai models. Possible icing of the indoor unit.
