Kolin if40 2c1m kolin 3tr inv floor mtd aicon. Sceen monitor display error. P6

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.

That error means that the controller boards in the inverter are bad. This is either a major overhaul of the boards by replacing them, or replacing the whole inverter.

Request the manual from Kolin.

My personal suggestion would be to go for these repair catalogs. I know this website reliable-store.com that i used to buy them from, and they have
online it was very good manual. Go ahead, I bet.
