It could be a faulty motor, a blockage preventing the fan from spinning, or a wiring issue. Check for obstructions and ensure the fan can spin freely. If not, you might need a new fan motor.
• E7: Communication error between indoor and outdoor units. This means the indoor and outdoor units aren't talking to each other. It could be a wiring problem, a faulty control board, or interference. Check the wiring connections between the units. If the problem persists, a technician will need to investigate.
• F3: Discharge temperature abnormality. This indicates that the temperature of the refrigerant being discharged from the compressor is too high. This can be caused by a number of issues, including a refrigerant shortage, a faulty compressor, or a blockage in the system. A technician is needed to diagnose the root cause and make repairs.
• H6: Indoor fan motor feedback error. There is a problem with the signal coming from the indoor fan motor. It may be a wiring problem, the fan motor has failed, or the control board is damaged. If the problem persists, a technician will need to investigate.

These are just a few of the many error codes you might encounter. Always refer to your Daikin AC's user manual for a complete list of codes and their meanings. If you can't find your manual, you can usually download a digital copy from the Daikin website. Remember, some repairs are best left to the professionals.
