This video will explain what an E3 and F5 Error code is on a Mini-Split Inverter unit, and how to clear the Indoor/Outdoor fan speed is operating outside of the normal range.
Thank you very much for these troubleshooting tips, although I can't say my F5 code was particularly hard to diagnose. My outdoor unit is subject to copious amounts of snow and moisture and there was a 1-inch layer of ice inside the unit, and it was holding the fan captive, after breaking all the ice away and bending the motor mount back down with my boots, I reinstalled the fan and voilà! It works again. Still, seeing how you checked the outside helped. The real fix now is building a small enclosure, so it doesn't happen again. :)
Hi please, I have a Koolking air conditioner, before it gave me error P4 I disconnected the power for about 5 minutes and it restarted without problems, now after a few weeks it gives me error F5 and does not want to know more than throwing cold air, the external fan does not turn more and ne the engine, what could be the damaged temperature probe? Waiting for your reply thanks and congratulations for the videos
