I have just installed mitsubishi heavy below cieling split system.
the unit is on a hard wired controller.
problem is the indoor fan motor runs for a couple of seconds the cuts out then starts straight back up again and repeats this process.
this happens in all modes
the unit sometimes stays on with no problem.
you can hear the relay on the pcb clicking as fan stops and starts.
there is no fault code on the controller
or irregular led lights on indoor or outdoor units.

strange one
can anyone help
