Analysis Codes
E2 = room temperature sensor failure
E3 = coil sensor failure of evaporator
E4 = abnormality of the outdoor unit evaporator coil sensor
E5 = no power supply fan motor
E6 = protection signal for lack of energy.
E7 = miscommunication between units
E8 = overheating protection.
DF = freezing indication, cold-protection indication: image of a propeller fan stopped.
Some other models:
E1 = Error eeprom
E2 = communication failure
E3 = Fan uncontrolled evaporator
E5 = open room temperature sensor
E6 = open evaporator temperature sensor
EC = refrigerant gas leak. Note: To proceed in this case. First turn off the circuit breaker, wait a few minutes. Connect and turn on the device, note whether internal fan works. Change speed sometimes. After that go to the external drive and make sure it connects fan and compressor. If so, the high valve freezes. Or hold both and feel they are freezing. If you are not sure it is a gas leak in the system.
If the unit turns on and after 30 minutes presents the EC code can not be sensors but lack of gas!
