Indoor Unit PCB Not Working

About This Service

When the indoor unit PCB is not working, the air conditioner may fail to turn on, respond to the remote, control temperature, or operate the blower and sensors correctly. This problem is often caused by voltage fluctuations, moisture damage, short circuits, burned components, or internal electronic failure. Our skilled technicians inspect the indoor PCB, check power supply and connections, and identify whether repair or replacement is required. We use safe repair methods and genuine components to restore proper communication and smooth AC operation, ensuring reliable cooling and long-term performance.
