If this is a ductless mini split e4 appears to be an air temp sensor on the indoor or outdoor unit that is sensing an abnormal reading. Check air filter and both I.d & o.d coil cleanliness. Its hard to troubleshoot without a model number. If its a 38g or 40g in the model number its a discharge temp sensor reading high temp situation (dirty o.d. coil, low freon, refrigerant restriction.

How to rectify E2 error in tcl split ac

I have the same problem..but i fixed that. if u have the same type with mine; TCL split type ac, TAC-42CF/A,380V 3N~. Then u can try this.
1. open indoor panel.
2. find 2 cable in socket pcb that is p11 And P12, u plug p12 on p11,and p11 on p12.
3. if not solved, try the same just like point 2 on power suply 3phase cable R.S.T try S to R, or else.
4. hopefully ur problem solved.

indicates dirty evaporator fins that are icing up
that will overload the compressor and trip it
the ni oise you hear is the ice breaking up and the splashing is excessive water in the blocked drain that cannot run outside
get in a technician to clean and service the ac

salaams check indoor coil temperature sensor , regards

Check for communication from indoor to out door.Check power in out door unit. If not, check the following.
Keep cool mode and temp setting minimum 3 degree less than room temp.
Check indoor unit return air sensor. Disconnect sensor from PCB and measure resistance. 8 kOhm at 30C and 13 kOhm at 20C if not replace air sensor

Check Indoor Pipe Sensor Disconnect from PCB and measure resistance. Pipe sensor = 5kOhm at 25C. If not replace pipe sensor.
Thanks and hope helpful?

I have the same problem with my TCL unit. I have had the Tech out to day and I am told it is an internal senor in the unit that fails. I am informed by the tech that this is a very common fault with the TCL unit. Also if you live in Australia like me prepare yourself for a fight with TCL due to them not liking to honour the 5 year warranty. I would not recommend this product to anyone
