Try changing the batteries. You may be losing communication between the remote control and the air conditioner’s control system. All remote controls are fitted with batteries that must be changed every year. We recommend you change all three AAA 1.5 Volt Alkaline batteries (do not use rechargeable batteries). If this has not fixed your problem, your air conditioner may need to be serviced. To book a service click here or call 1300 650 644 to be directed to your closest authorised Seeley Service company.
