When was the last time you cleaned the washable filter located behind the front flipup door of the unit? All mini-split systems are notorius for having dust build up on the blower vanes and as it runs it pulls humidity out of the air causing that dust to become like a past e

and changes the angle of attack on the blower cage. Check your filter and take some compressed air and blow it out real good and see if that helps.

    It may be that you have a leak. If the compresser ices up along with your indoor coil you could be low on refrigerant. Mini-splits are known to leak at the compression fittings at the back of the indoor unit and outside where the refrigerant lines hook up. Would suggest having someone take a look at it before you do any damage to the unit. What part of the country do you live in that your using the AC in the winter?

    Your liquid line, smaller one, should be warmer. There is other things that could be wrong and without seeing it I cant really give you a on the spot answer.You may also have an expansion valve that isnt working properly. I still would steer towards the blower motor though. If bearings are starting to go it could be going out on internal overload until it cools down and then starts back up.

Can a Fujitsu compressor unit be connected to multiple inside evaporator units that have different tonnage ratings. 18,000 BTU compressor and 9,000 & 12,000 BTU evaporator units inside.


call fujitsu engineering division direct and ask them about what is connected and if it works ok
logically as each evaporator has it's own tx valve as long as the compressor is large enough to run all together it should work but get the right information from the fujitsu experts

split air cons come in both configurations and are mostly in the last few years with inverter systems
you can get cooling only or cooling and heating systems
some brands only have the cooling only on the smaller units ( 8000 btu units)

How much more efficent is this than my 40 yr old janitrol 125000 btu beast


not knowing what you are replacing it with, it is hard to give a reasonable answer ( old sealed units against split system converter ac units )
However if you work along these lines, you will come to a logical decision
First off the old machines had the compressor operation tied to the thermostat setting so the compressor ran full blast until the room cooled to the set temperature. Then it stopped and remain stopped until the room heated up. At this point the compressor restarted and that is the point the the most power is consumed
again it runs full blast until the room again cools and switches off
So you can see that you have a varying room temperature and high energy consumption on start up
Now compare that to inverter units
The compressor is running all the time ( no high energy start ups every 10 minutes or so) but the compressor becomes less efficient as the room cools down
Still running at full rpms but the controls reduce the compressing action--less power to run the compressor--so there is a reduction in power used
The temperature variation is reduced because as the room warms a bit the compressor pumps a bit more gas and doesn't start at full load as per the old unit
Next , the latest units have better temperature / humidity recognition controls so they can be set at night so a room maintains an ambient temperature /humidity so that as the night gets cooler and the air drier you don't wake up freezing
It will even get to the point where you wonder if the unit is working
Lastly you can run the unit at a much higher setting ( 27 Degrees c instead of 24 or less and have the same comfort level as at 24-25 degrees c)
lastly warranty is for 2 years at best and parts will be available for the next 10 years against parts for your old unit

3 split units run from one compressor one is not cooling


If there is 3 indoor units from one condensing unit
(6 pipes at outdoor unit) this is classed as a multi unit

All units will run correctly as long as they all require same mode, cooling or heating, if one unit decides to heat it will shut down until master unit decides to heat then it will start, for each unit to individually heat and cool there would have to be 3 pipes to each indoor,

My new LG mini split 24,000 BTU unit is Freezing up on the small tube side. Not cooling properly. I thought freezing up (low on freon) but wouldnt it be on the larger tube. Is it running the fluid...


The larger tube is the return tube for the hot freon gas from the evaporator. The small tube is the cold freon after is has gone through the condenser where gas is condensed to a liquid when the heat is removed. So I would say your system is low on freon.
