In brief
Fault code 1E on Toshiba RAV / Estia means: Code 1E is a critical safety: the temperature measured at the compressor outlet (TD sensor) exceeds the limit (often > 110°C). Most common cause: Lack of refrigerant (leak), electronic expansion valve stuck closed, or discharge sensor (TD) offset/defective. First action: Attach gauges to check the gas charge (low pressure too low = leak).. 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 Handbook, the TD sensor typically reads 50 kΩ at 25°C.

What does fault code 1E on Toshiba mean?
Code 1E is a critical safety: the temperature measured at the compressor outlet (TD sensor) exceeds the limit (often > 110°C).
Lack of refrigerant (leak), electronic expansion valve stuck closed, or discharge sensor (TD) offset/defective.
Symptômes
- Poor performance before the fault
- Pipes very hot to the touch
- Compressor shutdown
Diagnostic
1. Pressure check
- Attach gauges to check the gas charge (low pressure too low = leak).
2. TD sensor check
- Measure the TD sensor on top of the compressor (typically 50 kΩ at 25°C for Toshiba, note varies by model).
How to reset fault code 1E on Toshiba?
Find and repair the gas leak, then recharge. If the charge is correct, replace the TD sensor or expansion valve.
When should you call an F-Gas engineer?
Code 1E most often appears during air conditioning operation, especially on RAV / Estia. Poor performance before the fault
Field context
Code 1E most often appears during air conditioning operation, especially on RAV / Estia. Poor performance before the fault
