TS06-INV: Refrigerant Leakage Detection diagnosis and solution
Description: Define the evaporator coil temperature T2 of the compressor just starts running as Tcool.
In the beginning 5 minutes after the compressor starts up, if T2 < Tcool-1°C(1.8°F) does not keep continuous 4 seconds
and compressor running frequency higher than 50Hz does not keep for 3 minutes, and this situation happens 3 times,
the LED displays the failure code and the AC turns off.
Recommended parts to prepare:
