SOURCE: System will not start up.

This is a signal fault between the indoor and outdoor first make sure the dip switches are set start with the unit closest to the condensor set as unit 1 then next unit as 2 and so on the dip switches are inside the indoor unit on the pc board if you check the manual it will tell you which swithes to set, if this wasnt done when the units where installed they would have never worked i would also check the signal wiring between the wallmount and the splitter box / bc box and make sure there isnt a loose connection when you have ruled this out id say more than likely it is a faulty indoor board on the wallmounted unt

Hi.

Here error codes:ERROR CONTENTS

Here a complete service manual.

Here user manual.

Before doing anything else, power down the main circuit breaker, so to power down each unit and reset the electronics in the whole system. If all units have gone down at the same time, this will often solve the problem.

Regards.

Ginko.

MY FIJITSU inverter is not working correctly, the timer light is flashing continuously and the timer lights flashes 5 times can anyone help pleawe


fujitsu is a good brand.
try one of these two things:

Turn the unit off then on again. After that press test button on remote control (rear side) and look how many times now operation and timer LED flashes. Note that. Then press MANUAL/AUTO button on indoor unit until you hear 3 beeps from buzzer. That will erase error memory.
Switch off and than on unit and see if indication repeat or it is gone. If it is gone, keep using your unit.
If it is repeated post your notes here.

OR+++++++++++++++++++++FOR OTHER MODELS

5 x Operation flash and a constant Timer flash indicates an outdoor unit control error. With this code flashing on the indoor unit, you need to point the remote at the unit and push the test run button. The flash pattern will change to a continuously flashing Operation light and a number of flashes of the timer light which gives more detail on what the error is.

To get the unit to try to restart you need to push and hold the manual/auto button on the indoor unit for a few seconds then reset the mains power supply but leave it off for a minute or so for the unit to power down completely. If you are going to try this make sure you make a note of any error codes first if you have to get someone out to look at it, it will help them a lot.

Fujitsu inverter air cond. Just stopped working properly. Model outdoor AOT30PMAL indoor unit AST30PBA-W. Code oper. Red led flashes fast continously green led (timer) repeats 13 slow flashes. After power...


It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.
