This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

IGBT or power module failure in inverter board, Overheating of inverter heat sink, Loose DC bus connections, Internal inverter control error

Safety: Inverter circuits store high voltage even after power is removed. Do not touch inverter components unless you are a qualified technician.

User checks:

Ventilation: Ensure the area around the Fairland unit is clear for airflow. Do not block side panels or louvers.
Power cycle: Turn off power at the breaker for 5 minutes, then restore power and see if E14 clears.

Technician tasks:

Inspect and test the inverter power board, including DC bus capacitors and IGBT modules.
Replace the inverter PCB if internal faults are confirmed.
