No beep or 'beep beep' sound — Remote controller signal not received

What does No remote control signal beep mean?

When you operate the air conditioner using the remote controller, the indoor unit should emit a 'beep' or 'beep beep' sound to confirm that the signal has been received. If no sound is heard, the signal might not be reaching the unit.

• Remote controller is out of effective signal range from the indoor unit.
• Obstructions are blocking the path between the remote controller and the indoor unit.
• Remote controller batteries are low or completely depleted.
• Interference from inverter-type fluorescent lamps in the room.
