Question about Fujitsu Heating & Cooling

HELP!!!! We just installed Fujitsu A/C system

HELP!!!! We just installed Fujitsu A/C system consisting of AOU24RML1 and AOU36RML1 outdoor units with five indoor units (ASU 12RMLQ and ASU9RMLQ).

The system has not worked consistently since the installation. Whether the cold air blows from the unit appears to be random and independent of the temperature of the room, the temp. setting on the wireless remote or the outside temperature. While the blowers appear to be working fine, the problem is that the air being blown is never consistently cool. Even the indoor units supplied by the same outdoor unit would work inconsistently, i.e., while one unit would continue to blow cold air, the other unit would blow only tepid. This would be the case even when the temperature of the rooms are about the same. For example, we've had 90+ Fahrenheit weather in the area and with the wireless remote temperature set to 68 to 70 degrees, the system would sporadically and barely cool the rooms down to maybe 78 to 80 degrees.

I've also noticed that copper tubing connected to the condensor unit outside would be covered with ice when the compressor is running.

Any ideas/suggestions would be greatly appreciated. So far, the installer is insisting that this is a design flaw of the Fujitsu system. And I've only received perfunctory response from the Tech Support at Fujitsu USA.

SOURCE: Non-cooling

- Calibrate your electronic thermostat if it is accurate. If not then replacement is needed.
- Check the location of your electronic thermostat, it may be installed in the room where its too cold.

SOURCE: York Mini-Split Not Cooling? : (

This can only be a gas problem.
the split units goes on on and off if a shortage of gas is involved, the chances that you would here it wont be that big for the fans would make too much noise.
get a repair man for a re gas and all is well.

Good luck.

SOURCE: The 10,000 BTU portable room a/c unit is not running cold enough

Make sure your vent is closed. check the filter to see if its clean. If you run the a/c you can check your evaporator to see if you have condensation or does it freeze up?
Make sure you have your unit on early in the morning. If you turn it on in the afternoon the humidity might be too much and it will take along time to cool down.
Try those things if that doesnt work then you need a service call.

I came across a brand new Fujitsu Split System out door unit (AOTR24JCC), so Im look for the indoor unit (ASTA24JCC) Where can I find one? Thanks


Model is over 5 years old so unlikely to get a new one. However, the outdoor units fail while the indoor is good so check eBay or your local installer.

The operation and timer lights on my Fujitsu split system are flashing on and off several times when the unit is switched off I noticed this after the system had stopped blowing air & I knew the room...


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.

Have just installed a Fujitsu Asta 24lC air con heat pump problem


Hi Shannon,
I would pursue your fight with Fujitsu, normally their units are reliable:(
It could be a really simple problem or a really complex one ranging from many componenets. A air conditioner has many more components that people may think. Keep fighting to get the unit repaired will it is still under warranty, after that Fujitsu wont want to know you. It could also be a wiring and refrigerant fault. Call Fujitsu out again.
I take the time to answer your question, so please rate me.
Thankyou Mat

Split unit, I get heat but no cold


I have run into this with the LG brand systems. try shutting power off to the outdoor unit to reset all units. If problem persists, it could have to do with a charge level of refrigerant (freon) or possibly a failed control board.

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
