⚡ Microcontroller Error Codes
Lloyd (Havells) Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| E1 | Indoor room temperature thermistor open or short circuit | Measure thermistor resistance 10k ohm at 25°C. Replace sensor probe. |
| E2 | Indoor copper evaporator coil sensor open/short | Check coil thermistor harness connection, replace coil sensor. |
| E4 | Indoor cross-flow fan motor malfunction or locked rotor | Check fan wheel cleanliness, inspect fan motor Hall sensor feedback. |
| E5 | Indoor-outdoor communication lost | Check 4-core cable connectivity, verify 24V DC communication bus signal. |
| F1 | Outdoor IPM power transistor module protection trip | Inspect outdoor PCB heatsink mounting, check IPM UVW output. |
| P1 | High discharge line temperature safety cut-off | Check for refrigerant leak, vacuum, and recharge virgin R32 by digital scale. |
