The error code 'F5' means that either there's a fault with the outdoor fan motor or outdoor PCB.
To fix the problem and to see whether or not there's a problem with your outdoor fan motor or outdoor PCB you'll need to do the following:
- Isolate the unit from the power then spin the external fan blade by hand - the fan blade should spin freely with no resistance and no (concerning) noise. If the fan does not spin freely or a grinding noise is heard then the fan motor needs replacing.
- If the fan spins freely with no noise then there is a fault with the external PCB, the external PCB sends voltage to the fan motor. Check the fan motor is connected firmly to the PCB. If there's no fault with the connections then the external PCB needs to be replaced.
To get a new fan motor or PCB you'll need to contact us via email at info@airconditioningcentre.com or call us at 0370 3344 556.
