Daikin split on server room tripped on HP cleared coil still tripping. Unit will start and run fine for about 5 mins then the condenser fan stops before the compressor causing pressure to rise. Is it just a faulty circuit board or am I missing something simple:confused:

If its a faulty probe then why is it only stopping the fan and not the compressor please explain

If that unit has condensation control, than it could, after some time programed in controller, control condensation by switching ON-OFF condenser fan. If probe gives wrong information, than it could think that condensation is not high enough (like in cold winter days) and turn off condenser fan.
If you provide model # than we could check if that is the case here.

Faulty outdoor PCB. I have done three of them already with the exact same symptoms ..... changed the PCB and all ok. :)
