First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.

hi,
If the unit displays Error E4

1)Check whether the winding resistance and
operation current of the compressor are normal.
2)Check whether the high and low pressure is normal
when the unit is running.
3)Check (whether the coil pipe sensor is normal)
whether the contact of the inserted on the circuit
board is well, the coil pipe temperature sensor is
fixed, the evaporation of the indoor unit is well,
the key is to check the evaporator temperature
detected by the coil pipe temperature sensor has
reached the cooling or heating temperature.
4)Check whether the surface of the condenser is too
dirty, it should be cleaned when it is too dirty.
5)Check whether the capacitance of the outdoor motor
and the fan is damaged, it should be replaced when
it is damaged.
6)If the above items are normal, the electric control
board should be replaced.

Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thank you for using fixya have a nice day:-)

Ductless Split Air Conditioner Review


Ductless split air conditioning units are the very best thing for some situations. Of course they can be installed in the place of most any central air conditioning unit. They also are a very good alternative to window air conditioning units. I will explore the use of these units more closely and look at how they can be used effectively.
One of the many problems encountered by the professional is when they are asked to install central air conditioning in an older home that was never designed with air conditioning as even a possibility. The walls may be very thick stone. Often they have very little or no insulation. The floor structures may be rough cut lumber. The joists spacing may be random. Walls and ceilings are plaster and lathe. Basically everything is stacked against any type of ducted central air conditioning. Many log style homes also are not very easy to get any kind of ducted central air conditioning installed. The open ceilings and the bare log wall design does not allow for any kind of ducting. I'm sure there are other situations. These are the ones that I have come across most frequently.
If you have a home or building that falls into one of these categories you may want to investigate installing a ductless air conditioner. This type of air conditioner can be installed in almost any home or building. The small indoor unit can be attached to the wall with a few screws. Most of the units only require that a three inch hole be bored through the outside wall. In new installations the units can be placed on inside walls with some fore thought and planning. For installation in older homes or homes that are already built you will want to plan the units to be on the outside walls.
The outdoor condenser units can be placed up to one hundred feet away from the indoor units. One outdoor unit can be used for many indoor units. Up to four indoor units can be attached to the same outdoor condenser. Some very advanced electronics will control the operation of the condenser and compressor to supply the refrigerant to the indoor air handler units that are running at the time. With variable speed technology the compressor and the condenser fan will only run as fast as needed. This technology has become very efficient in the last few years. You do not have to give up any efficiency with these ductless split units.
Another advantage to these mini split air conditioners is that they can be controlled to run only in the rooms that you actually need air conditioning in. If you are not going to be in a room you can shut down the unit. The units also have timers that can be set to turn the air conditioning on or off at preset times. If you are not going to be home all day the air conditioning can be setback or turned off. The timer will turn on the air conditioning so that you return to a cool house. Central air conditioning is very hard to zone effectively. Also with large central air conditioning systems the outdoor compressor will be running at full capacity even though only a few rooms amy be calling for cooling. There are some central air conditioning systems that are do some staging and variable speed technology. These are not as efficient or as effective as the ductless split technology.
Ductless split heatpumps are another great idea to look at. For a few dollars more you can also very easily have heat from your air conditioning mini split. Then especially in the mild spring and fall weather you can have some very efficient heat with out starting up that big monster of a furnace or boiler in the basement. In southern climates the heatpump version of the ductless split system may provide enough heat year around.
Ductless split air conditioning is definitely something that can solve many problems for some homeowners. Add to that the many advantages of these units and you will find that they are worth every penny that you will invest into them. As with any project like this make sure that you screen your contractor. These units are not for do it yourself people. There are many things that need to be done correctly for these units to work properly and efficiently. A refrigeration license is also required to install these air conditioners.
By doing a little research and hiring the right person you will enjoy many years of trouble free service from your new ductless mini split system.

If it happens in heat it must happen in cooling. The indoor unit has nothing to do with if it's heating or cooling. You likely have 2 moving parts in the machine, the blower wheel and the swing fins. Turn swing option off, eliminate that. You get the rest...

Fujutsu mini-split 'discharge termperature abnormal' error code


This unit is what is called a Heat-Pump.It has a reversing valve in the condensing unit outside which switches you're system from cooling to heating via this valve.It has a ball bearing inside this that opens a port, and slides to close off another port to reverse the flow of freon from one season to the other.If your code indicates discharge supply air temp. abnormal, you are having a problem of some kind in your out door unit.Even though its new, I have seen these ductless split systems fail within a month. I'm am not saying that you have a lemon, just pointing out they do have problems with main board failures, Freon leaks at line connections because they are not brazed like systems with ducts. But, being this new, you should have this unit still under warranty!! For me to trouble shoot this online would be a long task, I would have to be on site. Call the Contractor now and get them out to make repairs right away. Compressor is normally a year warranty unless you get the 4 year Extention.Failures happen like this on all units, not just yours. It could be many small things that would cause a low discharge air temp. Get them back out!
Sincerely,

ductless mini split units are a very good choice!  they are obviously quieter, more efficient and easier to maintain than window units. the downside is the initial expense of buying the unit, but this is paid back in eletric savings and peace of mind. Good luck Peyton
