1E • Toshiba • RAV / Estia
Fault code 1E Toshiba: Excessive discharge temperature
Code 1E is a critical safety: the temperature measured at the compressor outlet (TD sensor) exceeds the limit (often > 110°C).
Proof status : Manufacturer reference needed for the exact range

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.
Symptoms
- Poor performance before the fault
- Pipes very hot to the touch
- Compressor shutdown
Diagnosis
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).
Repair and return to service — Toshiba fault 1E
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?
Contact an F-Gas registered engineer if the fault returns after basic checks, involves refrigerant charging, or requires PCB or compressor replacement on Toshiba RAV / Estia.
Field context
Code 1E most often appears during air conditioning operation, especially on RAV / Estia. Poor performance before the fault
