    i resolved the problem code ch33 means in short term needs more charge.and yes i have a universal certification for over 10 years now, the code comes up on both units the lg installation manuals never mention any codes but if you go to their web site you can find a list of codes and what they mean these dual zone art cool are a little more sensative than other single split systems

Post a little more information and by the way are you certified to handle freon? $10,000 fine if you are not.

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.

Compressor shutting down


FC IS FREON CHARGE, WHAT YOU ARE GETTING IS A HIGH PRESURE CUT OFF  FAILURE. THE LABEL PRESURE IS TEST PRESURE. THE RUN PRESURE ON LOW SIDE IN AC MODE IS ABOUT 65 AT 75 T0 80 DEGREES INSIDE AND ABOUT 200-300 HIGH SIDE AT 75 -85 OUTSIDE TEMP. IN HEAT THE LARGE COPPER LINE BECOMES HIGH SIDE HOT WHEN YOU FEEL IT. IF YOUR FREON IS LOW WILL WILL ALSO GET SHUTDOWN. YOU WILL NEED SET OF FREON GAGES AND CONTACT ME BACK

Does not heat or cool


Hi, If the outdoor unit is running, make sure the fan is on also. If the system is new and has just been installed, it sounds like you may have a freon leak and have lost all its freon. Turn it on cool and let it run for a few minutes. Go outside and grab hold of the larger copper line coming out of the unit. It should be nice and cold and sweating. If not, and the fan and compressor are up and running, you have a leak and lost its charge. Check this and get back to me and let me know what you have found. We can go from there.

PS, When these installers put these units in, they sometimes get in a hurry and there welds are not very good and will leak over time, just to let you know.

I have a Toyo Aircon TA 12C(H)S air conditioner that shows E3 on the readout and nothing will come on. Any ideas what the error codes mean?


TOYO mini split air conditioner made in Japan is very very good quality and it can runs for 20 years without any problem. E3 means low pressure of refrigerant. You didn't hire a best ac technician to install your TOYO unit. The tubing connection between indoor unit and outdoor unit is not the right torque and refrigerant leak. Your TOYO unit runs out of refrigerant. You need fix the leak and fully charge the system. You will solve the problem. Good luck to you!

Senville Mini Split Error Code


thanks for your question, you will need a set of gauges on the unit to determine if the unit came precharged, if it didn't then you will need to vacuum down the unit, at least three times, after each time release a little 410a into the system them evacuate again, 410a is bad for drawing moisture, did you put an in-line filter dryer on as well ? after you find out about the freon level, then look at the name plate rating for amount of 410a needed, before adding the freon, use nitrogen to leak check the system, then weigh in the proper amount of 410a, unit should run really well after that, hope that helped, thanks again for your question, please feel free to come back if you have any more questions, thanks, mr.grzz
