Split System AC Error Codes:
When an error occurred in the air conditioner, an error code and indoor UNIT No. appear on the display part of the remote controller. The error code is only displayed during the operation. If the display disappears, operate the air conditioner according to the following “Confirmation of error log” for confirmation.
|Error Code||Cause of fault|
|E01||No communication between a remote controller and an indoor unit.|
|E02||Local controller failure - unable to transmit|
|E03||The master indoor unit receives no data to A-B|
|E04||Indoor unit (except twin slave) receives no communications from the outdoor unit; can also include klaxon on discharge pipe of an outdoor unit|
|E08||Duplicated indoor unit address|
|E09||2 local controllers connected on a group - both configured as masters|
|E10||Indoor unit PSB failure|
|E18||Communications failure between master indoor unit and slave indoor unit or units
|F01||Indoor unit TCJ (Liquid) sensor error (Open or Closed-circuit - resistance is measured in kΩ|
|F02||Indoor unit TC2 (Vapour) sensor error (Open or Closed-circuit - resistance is measured in kΩ|
|F04||Outdoor unit TD (Discharge) sensor error (Open or Closed-circuit - resistance is measured in kΩ|
|F06||Outdoor unit TE (Coil) sensor error (Open or Closed-circuit - resistance is measured in kΩ|
|F08||Outdoor unit too (Ambient) sensor error (Open or Closed-circuit - resistance is measured in kΩ|
|F10||Indoor unit TA (Return Air) sensor error )Open or Closed-circuit - resistance is measure in kΩ|
|F29||Indoor unit PCB failure|
|H01||Outdoor unit inverter compressor overcurrent detected|
|H02||Master outdoor unit over current detected shortly after startup|
|H03||Current detected on Master outdoor unit whilst idle|
|H06||Outdoor unit Low pressure detected by Ps sensor (0.2 bar -n 2.9 psig)|
|L03||Indoor unit Duplicated master indoor units in a group|
|L07||Indoor unit in a group of units previously addressed as a single unit - check to address|
|L08||Indoor units address not set - check to address|
|L09||Indoor units capacity not set (check DN Code 11)|
|L29||Outdoor unit IPDU error (Number of detected IPDU units is reduced)|
|L30||Input on indoor PCB CN80 circuit for 1 minute|
Toshiba Portable AC Error Codes:
Shows the set temperature in °C (Degrees Celsius) or °F (Degrees Fahrenheit) and the Auto-timer settings. While on DRY and FAN modes, it shows the room temperature.
Shows Error codes and protection code:
- E1 – Room temperature sensor error.
- E2 – Evaporator temperature sensor error.
- E3 – Condenser temperature sensor error (select models).
- E4 – Display panel communication error.
- P1 – Bottom tray is full – Connect the drain hose and drain the collected water away.If protection code repeats, call for service
