I may not be of much help but I may be able to guide you into some diagnosos. If there is a communication problem between the inside and outside unit, both on the inside and outside units a colored LED will bling 5 times then pause for 3 seconds. The 33 and 44 codes are confusing to me because I have never seen this. Try resetting the outside unit with no call for heat or cool from the inside unit. After about 20 seconds, restore power to the outside unit. Go in and turn on the remote and make sure you lower the cool setting more than degrees cooler than the room temp. After 3 minutes the outside unit should turn on. If you get an error code of either 1, 2 or 5 blinks document it for the technician. If you continue to get your 33 and 44, you have a bad control board. If all else fails, press and hold the button located on the lower left side of the art unit and hold for about 5 seconds. If it still no longer works, now you will need the help of someone who knows these units.

One thing you need to check is Polarity. the 2 wires red and white, need to be on the same terminals inside as they do outside. this is very important.

Hi!!
That means that the unit needs servicing, try cleaning the outside coils and cleaning the filter on the inside unit.

My carrier split ac trip after some time and green light blinking contsly


If this is a ductless split call a tech! The ductless split systems can be a troublesome unit to diagnose. A few things to try. Clean air filters and ensure coil behind is clean. And build up or debris on blower wheel (indoor fan blades) will cause unit to fault. Turn off power at breaker or disconnect and clean (with water hose and medium pressure) the outdoor coil. Be sure you will not damage outdoor coils fins with too much water pressure. Turn power on. If this simple service don't do it again, call a tech! Be sure to ask if they have someone who is experienced with mini split systems and be patient. Even the best technician will need to call carrier for tech support.

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
