⚡ Microcontroller Error Codes
Toshiba Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| P01 | Outdoor inverter unit driver / compressor drive circuit trip | Check IPM power transistor module and DC 310V bus voltage. |
| P10 | High discharge temperature protection trip | Inspect refrigerant suction pressure, check EEV opening, test discharge thermistor. |
| H01 | Compressor overcurrent or rotor lock detected | Measure compressor 3-phase UVW winding resistance balance; replace compressor if seized. |
| H02 | Inverter compressor driver circuit error | Check outdoor IPM heatsink thermal paste, inspect gate drive optocouplers. |
| E01 | Indoor-outdoor serial communication transmission error | Check interconnecting signal wiring, test terminal 3 DC pulse voltage 0-55V. |
| E04 | Unit communication miswire or address conflict | Reset indoor unit address switch, inspect TCC-Link signal bus lines. |
