SOURCE: My Fujitsu (AST9LSACW ) timer

Yes two flashes is indication of temp control setting problem.But still check this too:--- This are other reasons of poor cooling:-- ? Is the Air Filter dirty? ? Air the air conditioner's intake grille or outlet port blocked? ? Did you adjust the room temperature settings (thermostat) correctly? ? Is there a window or door open? ? In the case of Cooling operation, is a window allowing bright sunlight to enter? (Close the curtains.) ? In the case of Cooling operation, are there heating apparatus and computers inside the room, or are there too many people in the room? ---------------
? The air conditioner power has been interrupted by a power failure. The air conditioner will then restart automatically in its previous mode when the power is restored. ? Operated by setting before the power failure. ? If a power failure occurs during TIMER operation, the timer will be reset and the unit will begin (or stop) operation at the new time setting. In the event that this (kind of timer fault occurs the TIMER Indicator Lamp will flash . ? Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily disconnect the Power Supply Plug, reconnect it, and then use the Remote Control Unit to resume operation. ----------------- Also if your require user manual for your Fujitsu unit.Please click on the link below:-- http://www.fujitsugeneral.co.nz/scripts/get-manual.pl?manual_id=40 ------------ This should help.Thanks.Helpmech.

SOURCE: My Fujistu AST9LSACW split system

There are two things you can check outside before calling a service technician. The first is the breaker to the outside unit. There is a breaker or disconnect near the unit. If there is nothing wrong with the electrical supply, check the refrigerant level. If the level is low, the pressure switch will cut off power to the compressor to protect it from damage. DO NOT try to recharge the compressor yourself.

SOURCE: Fujitsu General ASHA09LAC Multi Inverter

Your split system is an inverter model. In it the compressor is powered not simply from the mains thru a relay but from a special and very complex set of converters: a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter to produce AC current of a desired frequency to power the compressor.
In your case the unit that provided the final AC current to the compressor has failed. The fact this happened a few days after you have started using it is a clear indication of manufacturing defect - some of the electronic components used in that inverter were of a low quality and they haven't been able to cope with the stresses so they failed.
This is something that only the dealer (and its repair crew) can solve and it's covered by the warranty - time to call them. And in the mean time disconnect the unit from the mains.

Fujitsu ASTA12LCC WILL NOT HEAT OR COOL. GREEN TIMER LIGHT FLASHES TWICE AT INTERVALS. FAN WORKING. IS IT REPAIRABLE?


Serial signal reverse error. Basically the outdoor unit is not talking to the indoor unit. This is normally due to damage to the outdoor controller PCB and it needs to be replaced.

Fujitsu asta18lcc has a constantly fast flashing green light and the red light flashes slower 5 times with a small gap between each 5 flashes. Unit wont work at all apart from lights.


The red light (operation) flashing 5 times can be one of four things depending on the green light (timer) but the green light should flash at the same rate as the red light, not faster - either 2,3,5 or 6 times. Anything other than these is abnormal and you will need a tech to diagnose.
Could be a faulty controller board or compressor.

My Fujitsu air con keep flashing operation,timer and economy .off the plug took out and on back still the same.took out the batery from remote and put back still the same..plss help me


It's asking you what mode you want to run your unit in. Do you want to run it in heating or cooling (operation), do you want to run it with economizer mode (economy), or do you want to run it with a timer setting (timer). Do cooling, no economizer, and no timer. This will make your unit run off off the setpoint you want. I.e. 72 degrees

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 Indoor Inverter ASTA09LCC/ASTA12LCC airconditioning - not cooling


If the operation button is flashing 8 times, the timer light should also flash 4 times in each sequence. This indicates a failure of the PFC circuit in the outdoor unit which basically means a faulty outdoor board and will have to be replaced.
If the operation light is flashing 8 times by itself, the indoor controller board may have a fault. You can normally test this by putting the mode on the remote to 'Fan' and checking that the controls otherwise work normally - louvers work as directed and fan speed changes correctly when selected on the remote.
Most likely the fault lies in the outdoor board but you should contact a tech to diagnose correctly.

Fault with 241C Aircon


This happen when you use the inverter for a long time and start getting old and over heat...try to power down the units and keep it for about an hour and then starft them again and try to install a small fan to keep them cool.
