Good day, what does L3 error code in kolin inverter window type mean?.

The L3 error code in a Kolin inverter window air conditioner typically indicates that there is a problem with the unit's compressor. The compressor is an important component of the air conditioner that helps to cool the air in the room by compressing and circulating refrigerant. If the compressor is not functioning properly, it can cause the air conditioner to stop working or to produce cool air at a reduced rate. Some possible causes of an L3 error code in a Kolin inverter window air conditioner include a faulty compressor, a malfunctioning compressor relay, or a problem with the unit's power supply. To troubleshoot the issue, you may need to perform a diagnostic test on the compressor or contact a professional for assistance.
