I have 4 header split type air conditioner. Time & again it stops and operation and timer light flash altenately and I have to to turn off the power at the switchboard and turn on again to reset. Sometimes this happens 2 or 3 times a day and other times it operates correctly for days. I have cleaned the filters and checked the electrical connections. 2 years ago I had a tech from Fujitsu who came and checked everything and could not find any faults. I am getting a bit concerned as this is occuring more often now Can you help?

Hi,
On the days it happens alot is there a temperature corolation??? Are these days warmer or colder then the days it runs all of the time???
Have you checked the charge on the unit???
Would there be any power surges or fluctuations???
It would seem also that this may be caused by a faulty sensor... but you will have many sensors between the five pieces of equipment that it could be and it may take it failing completely for you to be able to pin down exactly which it is...
You may be able to narrow it down by shutting off one head at a time and seeing if it still locks out... but that would take many days to make sure that you have found the fault...
Unfortunately there are probably no good answers to be had any time soon here and not without a ton of detective work...
