I would first check the condensate drain pipe. This can be done by blowing back into the drainpipe from outside. Not to worry it is not dirty or dangerous. Also make sure that your air filters are clean.

SOURCE: LG split (3 indoor) LMU360CE

The LED #2 is only flashing while in disconnection or short in Thermistor (3 sec off / 0.5 sec on). If you want to change it, note: this is not an easy job to do! You will need to remove the top panel, then remove the control paneland then the front panel to gain access to the thermistor. The part isnot available to the public and requires an authorized service techfrom LG to take care of this problem. You will need a special tool toremove the front door seal spring clamp.
But you can call customer service @ 800 243 000 and see if theycan transfer you over to parts. Just give them the model and serial #and see if they would be willing to sell you the thermistor part. Youwill also need the door seal spring clamp removal tool to make the jobeasier.

SOURCE: I have a problem with

3 blinks - return air sensor , the sensor that measures the temperature of the air going in the internal unit is reporting an excessive temperature or nothing at all.
8 blinks - fan failure
No, you can't repair it yourself, the control board, sensor and fan will have to be checked and most likely the fan motor replaced.

Initially fan in indoor unit was surging,cutting in and out,now has stopped completely and red/green flash twice followed by red flashing 4 times


The flashing indicates a fault code. Not knowing what make / model you have makes it impossible to determine the exact fault. If the indoor fan was running erratically, it may just be a fan capacitor on the indoor unit. Some units have a separate capacitor, some have the capacitor mounted on the main indoor control board. Check and see if the fan starts if you give it a flick to start it spinning when you turn the air con on. If it runs and the error flash does not appear, then you will know its a fan capacitor.

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.

I have a Fujitsu inverter split system,(ASTA18LCC) which the power was removed for a while. Now when you start it up on any mode the red operation light is on briefely, then the green timer light flashers...


To work out what the error code ispress the orange start/stop button on the remote controller so unit operationis stopped.
Then press and hold "energy save" and "zone control" buttonsimultaneously for at least five seconds, the error code will be along thelines of En:nn where the "En:" is the error code and the":nn" indicates the indoor unit address if there are multiple indoorunits connected to the one controller. If the upper vertical bar on the capitalE is missing so it looks maybe like a 2 or something don't worry for somereasons they just do that
Some common error codes are:
E0 Communication error between indoor unit and wired remote control, check ifthere is 12VDC between terminal 1 + 3 at remote control and 8-9VDC pulsatingbetween terminal 2 + 3. If DC volts out of Indoor pcb is below about 11.6VDC itwill cause this error, the problem is normally dry capacitors in the 12 VDCpower supply section. This model has two power supply sections on indoor pcb.
E1 Communication error between indoor unit and outdoor unit,
EF Discharge temperature abnormal
Is it helpful?

How do you retieve the error codes?


All Mitsubishi DLP Televisions have a built in Diagnostic Decoder to store the last fault in memory. This will help the Mitsubishi Technician determine what area or part defect could exsist due to your television not coming on or turning off by itself. In order to read the error code from the front panel lights, you need to know how to access this information if it is available.
Please remember not to unplug the tv from the power outlet because this will reset the error code. The television must be in the power off state or shut off state to retreive the code.
Error Code Operational Check
Note: The TV must be in “Shut Down” and not have been switched Off, to perform the Error Code Operational
Check.
Pressing the front panel “ACTIVITY” and “CHANNEL DOWN v” buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The “TIMER LED” flashes denoting a two digit Error Code, or indicating no
problem has occurred since the last usage.

Note: The front panel buttons must be used, NOT those on the Remote Control. • The number of flashes indicates the value of the MSD (tens digit) of the Error Code. • The flashing then pauses for approximately 1/2 second. • The LED then flashes indicating the value of the LSD (ones digit) of the Error Code. • The Error Code is repeated a total of 5 times.
Example: If the Error Code is “23”, the LED will flash two times, pause, and then flash three times, then this will repeat itself for four more times before the blinking stops. If you forget the code, you can start all over again after the LEDs have stopped blinking. Just remember you are looking for a two digit code, denoted by a pause in the middle.
Example: You are watching Television and after 20 seconds it shuts off with no picture or sound. By pressing on the front panel the INPUT and MENU at the same time starts the Diagnostic Procedure, and the TIMER LED will then blink six times, and then a small pause, then six more times. This is an error code of 66, and will indicate to the Technician a defect in the lamp ignition circuitry. This will help us to order parts for the repairs without guess work.
In addition to the above code retrieval procedure- most new Mitsubishi LCD & DLP televisions have a built in Error Code Log or menu system. To access this feature the television has to be on and have a picture or blue screen to read this fault menu . To read this Error Log in the television you have to use the Mitsubishi remote control and follow this procedure: Press & release the Menu button, followed by 3564 on the remote control. You will see Lamp time, Code & Status. If an error has happened, please read the numbers indicated under Code to our service person or office staff. We can determine by these codes how to handle service on your unit.

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
