How to check air conditioner error codes

Air-conditioner error codes vary by brand, series and model. Check the exact model and its manual before interpreting a code.

Service process

• Note the displayed code, indicator lights and model number
• Use only the unit’s manual or technical documentation to verify the code
• Stop using the unit if there is burning smell, smoke, tripped breaker or water near electrical parts
• Share the code together with symptoms such as poor cooling, noise, leaking or odour
