Remote control does not operate the indoor unit; no beep or response.

Steps:

• Replace batteries: Install new, high-quality batteries in the Gorenje remote, observing correct polarity.
• Check IR path: Ensure there is a clear line of sight between remote and indoor unit; clean the IR window on the unit.
• Test remote: Point the remote at a smartphone camera; pressing buttons should show a flashing light on the camera screen. If not, the remote is faulty and should be replaced.
• IR receiver: If the remote works but the unit does not respond, the IR receiver board or indoor PCB may be defective and require replacement.
