arrived on site to diagnose mini split that is currently showing a alarm u8. The alarm code means â€œcommunication failure with outdoor fansâ€. After trouble shooting I found f5 fuse was blown I checked Mitsubishi tech support forms and it states â€œ replace control board and both condenser fansâ€. I was not able to get in contact with parts distributor to check availability of components. I will need to call and check In the morning.
