When the error code 'FF' appears you can do the following to fix the problem:
- Check if the compressor runs for 1 minute and the outdoor fan does not start, this means there is a fault with the outdoor fan motor
- Check if the compressor and fan run for 1 minute and then shuts down, this means there is fault with the 4 way valve. Check the solenoid is connected to the PCB properly. Does the unit operate in the other mode, if so then the valve is faulty.
- Check the outdoor PCB for damage, if there are any burn marks then the PCB needs replacing.
note: commonly this error signifies the system is low on refrigerant. An engineer is needed to check for leaks and recharge the system.
