Indoor unit receives power (lights on) but will not start cooling or heating when commanded.

Steps:

• Verify mode: Set the Gorenje remote to Cool or Heat (not Fan or Dry) and set temperature well below (cooling) or above (heating) room temperature.
• Cancel timers: Check for any timer icons on the display. Cancel all timers and schedules.
• Remote batteries: Replace batteries and ensure there is a clear line of sight to the indoor unit IR receiver.
• Manual start: Some models have an emergency operation button under the front panel. Press it to test basic operation.
• Power reset: Turn off power at the breaker for 5–10 minutes, then restore.
• If still no start: The indoor PCB or communication with the outdoor unit may be faulty and should be checked by a technician.
