General information only

The error and fault code descriptions on this site are general reference information compiled from common industry troubleshooting patterns. They are not sourced from, endorsed by, or guaranteed to match any specific manufacturer’s official service documentation for every model and production year.

Brand names

LG, Samsung, Daikin, Voltas, Blue Star, Hitachi, Panasonic, Godrej, Whirlpool, Carrier, Mitsubishi Electric, and any other manufacturer names mentioned on this site are trademarks of their respective owners. This site is an independent reference resource and is not affiliated with, endorsed by, or sponsored by any of these companies.

Not a substitute for professional service

Air conditioners involve pressurised refrigerant, high-voltage electrical components, and moving parts. Nothing on this site is instruction for opening a sealed refrigerant system, handling electrical wiring, or servicing a compressor. Faults related to gas pressure, compressor failure, PCB damage, or wiring should be diagnosed and repaired only by a qualified HVAC technician or electrician.

Short-circuit / electrical hazard warning: if an error code is accompanied by a burning smell, sparking, a tripped circuit breaker, or a scorched plug or wire, do not touch the unit or its switch. Turn off power at the main distribution board (not just the remote), keep the area clear, and call a licensed electrician or authorised service centre. This site’s code descriptions are not a substitute for an electrical safety inspection.

Gas leakage / refrigerant safety warning: codes describing low pressure, refrigerant shortage, or gas leakage (for example Daikin’s U0, Voltas’ F0, or similar) can indicate a refrigerant leak. Refrigerant gas should only be handled, tested, or topped up by a certified technician with the correct recovery and charging equipment. Do not attempt to open refrigerant lines yourself. If you smell a strong chemical odour or hear hissing from the unit, switch it off, ventilate the room, and contact a professional promptly.

Service-related error codes: a number of codes on this site — PCB/EEPROM faults, compressor overcurrent, sensor failures, high/low pressure trips — are flagged in the tables as needing a technician rather than a self-fix. Treat that flag as a hard boundary, not a suggestion: these faults sit behind sealed or high-voltage components, and DIY attempts can void warranty, damage the unit further, or cause injury.
