20 Most Recent Fujitsu 24C1 Air Conditioner Questions & Answers


It is possible to do this, although it is not easy. It requires reprogramming the HMI in the unit. I am in the process of doing this on my AVN6606HD and it would probably apply to other units to convert from japanese to english.

The reset button on the AR-DL10 is the 'ACL' button. On my unit it is just above the Start/Stop button. On some of them it is in the battery compartment.

I have same problem like yours to my newly installed Fujitsu multi-split system (the first time use since system installed 1 week ago). I rang the electrician who did the installation; he said it must be the units themselves nothing to do with electricity.

Okay, then I rang Fujitsu and their local service agent. They suggested me to switch off C/B for an hour to reset the units. I followed the instruction but the indoor units still did not respond to remote control...

It simply looks like no power supply to indoor units (they are hard-wired to the outdoor unit). So I used a multi-meter to test the power terminals of indoor units (Danger! If you have no idea about this, don't even try! ): it seemed no power supply even C/B is on. I turned to the isolator which next to the outdoor unit. The isolator was making arcing noise when I switched it on and off. The indoor units suddenly turned on for few minutes then died again.

So I figured out the problem is that crooked isolator. I called the unhappy electrician to replace the isolator. End story....

I hope my experience will help you a little bit.

Check your remote control by using a camera or cellphone camera as your eyes to confirm if the remote control is ok. Point the remote control transmitter to your camera and check if a light emits in your remote control transmitter. If no light then the remote control is defective, but if the light is present then the remote is ok and the unit receiver board itself is defective.

Check also if there is a reset or rst button on the remote control, press the button and test the remote.

If your a/c is working on Heating mode the indoor fan will turn on after the preheating ( 2-5 min depend from outdoor temperature.). if after a few seconds the operation led blinks you have problem with it.Try to move it with some screw but attention do not broke it. If it move easily check the 1,5 or 2 ?F capacitor on the PC board and the 12V fan contactor is working. If all that are OK the trouble is on the fan motor.

Had similar problem (ie. 2 green & red flashed followed by 5 red flashes - Fan blowing but not cooling ... I also noted that the outside unit fan wasn't going). Tried restarting several time after waiting only a minute or two after turning the mains power off but with no change. So turned the unit off at the mains power and then fired it up about 2hrs later and it was all working fine.

Most likely low on refrigerant. This will cause the evaporator to ice up which will then drip in side the room as the outer surface melts. It also causes less air flow through the heat exchanger which exacerbates the problem. You need to find the source of the leak which is probably at one of the flare joins. Unfortunately, I don't have a service manual for this model so cant tell you what the error code is. Consult a local tech.

When sliding the bottom part of the remote down, you have to lift it slightly (I did this with a letter opener - very carefully) to pry the door up from two stops that normally prevent the dorr from sliding down too far. If you look carefully, you can see what I mean.

First check power or (high voltage) to outside unit if good make sure you have thermostat voltage or (low voltage) to the outside unit.
