Gree Air Conditioners Error Codes
The fault code is deduced from the number of
times the green LED flashes, blocking unit operation.
C5:Malfunction of
connector jumper: Check if the connector jumper contacts properly. If the PCB
is to be replaced, please take off the old for the new PCB
F1:Malfunction of indoor ambient temperature sensor:Check
if indoor room temperature sensor is connected properly.F2:Malfunction of evaporator temperature sensor:Check if the evaporator temperature is connected properly.
H1:Defrosting:It is normal
H6:Indoor fan block:Check if terminal of the indoor motor is connected properly. Replace the fan motor or the indoor board if disabled.
