Fujutsu mini-split 'discharge termperature abnormal' error code


This unit is what is called a Heat-Pump.It has a reversing valve in the condensing unit outside which switches you're system from cooling to heating via this valve.It has a ball bearing inside this that opens a port, and slides to close off another port to reverse the flow of freon from one season to the other.If your code indicates discharge supply air temp. abnormal, you are having a problem of some kind in your out door unit.Even though its new, I have seen these ductless split systems fail within a month. I'm am not saying that you have a lemon, just pointing out they do have problems with main board failures, Freon leaks at line connections because they are not brazed like systems with ducts. But, being this new, you should have this unit still under warranty!! For me to trouble shoot this online would be a long task, I would have to be on site. Call the Contractor now and get them out to make repairs right away. Compressor is normally a year warranty unless you get the 4 year Extention.Failures happen like this on all units, not just yours. It could be many small things that would cause a low discharge air temp. Get them back out!
Sincerely,
Shastalaker7
