These units are designed for precise cooling and humidity control. They are designed to run all the time. Although your cooling temp may be satisfied your compressor still runs maintaining that temp and dehumidifying as well. These inverters drop down to as low as 30% capacity and remain running which in fact is saving you electricity rather than stopping and starting.
Difficult for you to check this I'm afraid, if the fan on the cooling unit is working unless you have an experienced 'ear' you will not hear the compressor running or worse still occasionally clicking.
Possible faults are
1. Compressor not running (the fan will run even if the compressor does not) electrical fault
2. Compressor seized (consult your service guy) also true for the rest of these
3. Compressor not pumping
4. Refrigerant leak
Inverter compressor run current high. Check compressor windings all equal 1 to 4 OhmsCheck to earth 50 MOhm minimum, check run current. If high, winding is weak. Solution: Replace compressor.
I think, your compressor gets over heated due to condenser block-clean it. Less rpm fan speed. -Replace capacitor. 3.Check compressor running capacitor. If weak replace it. Helpful?
The turbo is in need of an overhaul/replacement. The problem is that people do not let turbo charged engines idle for at least 5 minutes before turning them off. The engine oil is coolant for a turbo much like antifreeze is to an engine. Exhaust temperatures reach up to 1700 degrees F and if the turbo is not cooled down, it will cook the seal that keeps oil from entering the engine. Have a shop that is experienced with replacing turbos do the job and it will cost quite a bit. Always cool down your trubo and it will last lots longer.
hi have you cleaned the matrix best done by blowing with air but a soft brush can work,make sure that all the cooling vanes are clear
hope this helps ian
