When entering this function, the indoor air volume will be reduced or no wind will be blown out, and cold air will be blown out during operation. This function is invalid in PMV mode/timer/sleep mode, and the duration of "CL" displayed on the remote controller and panel may be different. Haier's unique patented self-cleaning technology can quickly collect water vapor in the air, quickly decompose and remove dirt, and the cleaning process is worry-free. Haier evaporator's unique antibacterial coating has a high antibacterial rate of 99.99% and high efficiency.
Self-cleaning technology refers to the technology that the indoor evaporator of air conditioner cleans the indoor heat exchanger of air conditioner by self-defrosting and re-dissolving under the instruction of a specific program. By automatically cleaning the indoor evaporator, dust can be removed in time to prevent bacteria from breeding inside the air conditioner and ensure the air supply safety of the air conditioner.
F3 troubleshooting method
F3 represents failure of outdoor unit power module. Open the outdoor unit and check whether the cable is loose. If so, it will be fine after the connection. Please contact the after-sales or maintenance master for maintenance. Haier air conditioner displays F3, indicating refrigeration overload protection, that is, the evaporator of the indoor unit freezes, the wiring between the outdoor unit circuit board and the module is abnormal, the power module is damaged, and the outdoor unit memory IC 1 1 or the outdoor unit processor IC9 is damaged. It is suggested that the power should be cut off for several hours, and then the evaporator of the internal machine should be wiped clean before being powered on.
Failure to maintain the outdoor unit of air conditioner for a long time will lead to f3 failure, and it can only be used normally after maintenance or decontamination. High ambient temperature will lead to system protection. In the case of high environment and poor ventilation of the outdoor unit, the heat of the air conditioner cannot be blown out because of the screen or wall in front of the outdoor unit. When the temperature is too high, the compressor will automatically start the protection, stop using it for 30 minutes to 1 hour, and restart it to solve the problem.
