    Hi, my house unit is also having this issue but it is not happening daily, currently 3 weeks. Why is this so? Do you help to do checks? We used to have this issue in 2021 and Daikin is unable to find out root cause till they changed the entire PCB outdoor. Before this, they changed the valve indoor. What is the impact of not fixing this F4 alarm?

    previously daikin collected data for 1 full week and cannot find a conclusion till they changed the PCB outdoor. Now this issue comes back again but not on a daily basis. However there is still aircon during the blinking light period. After we turn on and off, the light stopped blinking.
