Gree Cassette AC Error Codes

  Gree Cassette AC Error Codes:
In case of malfunction (such as bad smell), turn off the power immediately and contact the  service center. Do not repair the air conditioner by yourself. Incorrect repairs may cause fire. Please contact the service center. The appliance should not be used by children without supervision.
Once a failure occurs with the indoor unit in operation, the green unit LED flashes at intervals of 0.5 seconds.
The fault code is deduced from the number of times the green LED flashes, blocking unit operation. Between one flash cycle and the next one, a pause of 5 seconds elapses.

 Error CodesSolution
E1High Pressure Protection. If outdoor unit detects the high pressure switch iscut off for 3-sec successively, high pressure protection will occur.All the loads (except the 4-way valve in heating mode) will be switched off. In thiscase, all the buttons and remote control signals except ON/OFF button will be disabled and system won't be recovered automatically. Switch off the unit or re-energize the unit after cutting off power to eliminate this protection.
E2Indoor Coil Freeze Protection. If indoor unit detects the evaporator temperature is lower than protective temperate value after the unit has been running for a period of time undercooling or dry mode, the unit will report this fault, in which case the compressor and outdoor fan motor will be stopped. The unit will not run until evaporator temperature is higher than the protective temp. value and the compressor is stopped for 3-min.
E4Compressor High Discharge Temperature Protection. f outdoor unit detects the discharge temperature is higher than protective temperature value, the unit will report high discharge temperature protection. If the protection occurs over 6 times, the unitcannot be recovered automatically. Switch off the unit or re-energize the unit aftercutting off power to reset this protection.
E6Communication Malfunction. If the outdoor unit does not receive data from indoor unit, communication malfunction will be reported. If there is communication abnormality between display board and indoor unit,communication malfunction will be reported.
E8Low Indoor Airflow. If the indoor unit does not receive signal from indoor fan motor for 30-secsuccessively when the fan motor is operating, indoor fan motor malfunction will be reported. In thiscase, the unitcan automatically resume operation after stopping. If the malfunction occurs 6 times within one hour, the unitcannot be recovered automatically. Switch off the unit or re-energize the unit after cutting off power to eliminate this malfunction.
E9Condensate Overflow Protection. If indoor unit detects the condensate overflow switch warning for 8-secsuccessively, the system will entercondensate overflow protection.The unit will shut off and will not recover automatically. Switch unit off and then switch it on to eliminate this malfunction.
F0Indoor Ambient Temperature Sensor at ReturnAir Inlet Malfunction. If indoor unit detects the indoor ambient temperature sensor is open circuit or shortcircuit for 5-secsuccessively, indoor ambient temp. sensor malfunction will be reported.The unitcan automatically resume operation after the malfunction disappears. If indoor ambient temperature sensor malfunction occurs in fan mode, only the error code is displayed and the indoor unit will operate normally.
F1Indoor Evaporator Coil Temperature Sensor Malfunction. If indoor unit detects the evaporator temperature sensor is open circuit or shortcircuit for 5-secsuccessively, evaporator temperature sensor malfunction will be reported.The unitcan automatically resume operation after the malfunction disappears. If evaporator temperature sensor malfunction occurs in fan mode, only the error code is displayed and the indoor unit will operate normally.
F2Indoor Condenser Coil Temperature Sensor Malfunction. If outdoor unit detects the condensercoil temperature sensor open circuit or shortcircuit for 5-secsuccessively,condensercoil temperature sensor malfunction will be reported.The unitcan automatically resume operation after the malfunction disappears. Ifcondenser temperature sensor malfunction occurs in fan mode, only the error code is displayed and the indoor unit will operate normally.
F3Outdoor Ambient Temperature Sensor Malfunction. If outdoor unit detects the outdoor ambient temperature sensor open circuit or shortcircuit for 5-secsuccessively, outdoor ambient temperature sensor malfunction will be reported.The unitcan automatically resume operation after the malfunction disappears. If outdoor ambient temperature sensor malfunction occurs in fan mode, only the errorcode is displayed and the indoor unit will operate normally.
F4Compressor Discharge Temperature Sensor Malfunction. If outdoor unit detects the compressor discharge temperature sensor is open circuit or shortcircuit for 5-secsuccessively after the compressor has been operating for 3-min, outdoor discharge temperature sensor malfunction will be reported.The unitcan automatically resume operation after the malfunction disappears.
F5Wired Controller Temp. Sensor Malfunction. If the wired Tether Controller detects open circuit or shortcircuit of its temperature sensor for 5-secsuccessively,wired controller temperature sensor malfunction will be reported.
H1Defrost Mode. System is defrosting outdoorcoil.
H3Compressor Overload Protection. If outdoor unit detects the compressor overload switch open within 3-sec successively, the unit will reportcompressor overload protection. If the fault occurs successively 3 times, the unit will not recover automatically. Switch off the unit or re-energize the unit to eliminate this protection.
H4Overload Protection. If indoor unit detects the evaporatorcoil temperature is higher than protective temp. value, the unit will report overload protection. The unit will restart operation after evaporator temperature is lower than the protective temp. value and the compressor is stopped for 3-minutes. If the protection occurs over 6 times, the unit will not recover automatically. Switch off the unit or re-energize the unit to eliminate this protection.
H6Outdoor Fan Motor Malfunction. If outdoor unit does not receive feedback signal from outdoor fan motor for 30-secsuccessively when the fan motor is operating, an outdoor fan motor malfunction will be reported. In thiscase, the unit can automatically resume operation after stopping. If the malfunction occurs 6 times within one hour, the unit will not recover automatically. Switch off the unit or re-energize the unit to eliminate this malfunction.
U7Reversing or 4-wayValve Malfunction. After the compressor starts operation in heating mode, if the outdoor unit detects the difference between evaporator temperature and indoor ambient temperature is lower than the protective value for 10-min successively, ReversingValve Malfunction will be reported and the outdoor unit will stop operation. If the malfunction occurs 3 times, the unit will not recover automatically. Switch off the unit or re-energize the unit to eliminate this malfunction.

LG AC Error Codes and Troubleshooting Split Type, Mutli System, Floor Standing, Cassette Type, PTAC Type, Portable AC, Troubleshooting and Manuals. If there is a fault on any  LG Universal Unit , a two digit number will appear on the remote controllers led display. If the unit does not have a remote controller the fault will be displayed using the LED’s on the front of the indoor unit. The “Units” digit of the fault code is shown by the power led which has the following symbol by it. This is usually Red, but on a few models it is Green. LG AC Error Codes and Troubleshooting The “Tens” digit will be displayed by one other led, usually the “Sleep” or “Filter” lamp Error Indicator: The function provides self-diagnosis and displays an error code if there is any trouble. Error codes are displayed on the Indoor unit’s Wired Remote as CH**, and/or Fascia Display. In addition, the code is indicated via LED’s on the outdoor unit control board. If more than two troubles
