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.

We have 2.0 HP inverter wall mounted LG aircon, when we turn on the ac, the indoor unit only is running and shut down after 3 mins. What is the solution?


Hi Marie, does the green indicator light on the front panel flash after it shuts down? If it does...count how many times it flashes this will refer to a fault code diagnostic.

Air con indoor unit is flashing 6 times out door is off


Please specify the make and model of your unit.
If this is a LG inverter model.
The six flashes of the indoor unit light indicates a CH 06 alarm.
This alarm state indicates that the indoor unit pipe temperature sensor has measured a temperature out of range or the unit is protecting itself from this low temp state. Indoor unit coil temperature to low. Should it have reached a temperature of -5°C for longer that 30sec it will switch the machine off.

It could indicate that the unit refrigerant charge is too low or the sensor has gone out of calibration.

It should measure 5kΩ @ 25°C

LG LS-Q09BUL INVERTER AIR CONDITIONER


This is possibly either a complete outdoor pc board error or an E-Prom error on the indoor pc board. You can try shutting down supply power completely for a minute and then switch on. These units also have a delay timer system which does not like to be switched on, off repeatedly in a short period. Please also check for reset button on the outdoor pc board. Hope this helps.
