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
