A non-cooling mini-split needed focused diagnosis
The customer reported that the ductless mini-split was not cooling. Because a no-cooling symptom can come from electrical, refrigerant, airflow, sensor, motor, or control problems, the technician evaluated the equipment before recommending a repair.
Diagnosis identified a faulty electronic control board in the outdoor unit. The board coordinates system operation and communicates with connected components, so a failure can prevent the mini-split from running or cooling as intended.
The faulty component was identified and replaced, restoring cooling without the expense and disposal of a complete equipment replacement.
Control board replacement restored cooling
The licensed HVAC technician replaced the failed board rather than condemning the complete mini-split. The individual project photos document the circuit board, wiring connections, and the Daikin outdoor unit with its service panels open.
After the targeted component repair, cooling was restored. Repairing the identified failure can preserve useful equipment life and reduce cost and disruption when the remaining system is still a suitable candidate for service.
