Look at the boards side by side, on the original board you will find a plug that's not on the new board (normally it's a plug with a looped cable in it but there are other versions, just a plug with internal short, the cable replaced by a resistor are the ones that springs to mind).Then just move the plug across.I checked- nothing.Most probably the company installed has removed them from the unit if there is or the DAIKIN company miss to fit one in the box.Is that mean that i can just a normal cable to brige it or there is a special resistor in that plug?Maybe my? Are stupid but DAIKIN are not the one which i use to services them) i dont know nothing about them ).Thanks in advance.P.s.-if someone can tell me the step by step what i have to do.Friday is the last day.Its in the school with sick childrens. Re the U2 error question from AOECan someone please help me. Have installed dakin 8kw reverse cycle split sytem in australia. Code is U2 Power supply insufficient. Still registers 235 volts. I have a unit that I personally have not seen, Unit Model = FTXS25D2 with fault code = A6 Fan motor, Lock/Overload.
The blades for the fan run freely, no blokages or grating. Should I just replace the part or could it be fixed?
Also could anyone offer me the schematic diagram or tell me how easy it is to pull the fan motor out of the unit. The reason I ask is the cliant is not local so I need to prepare in advance and never changed the fan motor in this unit before.Thank you in advance if anyone can provide me with some info.Cheers. Hmm, the unit once switched on calls for the outdoor unit and starts to cool/heat with compressor running and the indoor coil cooling/heating but indoor fan motor dosn't start, 60secs later unit shuts down to protect unit.Dose this still sound like a PCB Fault and how can I make a check for sure?
How can I check the PCB?Koy,This is the service manual for that model, start at page 152 for your A6 fault code.are other manuals on the Daikin site if you want.http://www.daikinac.com/residential/docsServiceSkyAir.asp?sec=docs&page=39. Possible reasons:1) Faulty fan motor.2) Faulty indoor unit's P.C.B.3) Fan motor cable broken or not connected (S1 connector on the P.C.B).I have to say that in my opinion the most likely fault here is that of a failed indoor fan motor capacitor.
Value will be between 0.7 and 1.2 microfarad. It will be soldered to the PCB and should be obvious. It is not a difficult job to de-solder and change. You may even be able to attach miniature croc leads and connect a new one first before de-soldering.Good luckTrevor. We have a 9 year old FTXD50JVEA which has an H6 fault code. Developed identical problem / symptoms under warranty. Compressor wouldn't run, but turned out to be the board.
Took 7 visits before they worked it out.History repeats now, but all personalities and records have gone.Any thoughts / suggestions?The engineer is surprised he is getting no output current from the compressor, even if it is not running.What sort of Mean Time Between Failure (MTBF) are companies like Daikin working on for boards, compressors and fans. We use for heating only, 2 months of the year, and only in the evening, so running only 18 months out of nine years. Are we unlucky or is this normal?
