What to Check First
- The batteries in the remote control are discharged.
- The circuit breaker has tripped.
- The remote control being used is not the one that was provided with your air conditioner.
- The air conditioner IR receiver is covered, or a tri-phosphor fluorescent lamp or a device that emits infrared light is nearby.
- The remote control is malfunctioning and requires a professional inspection.
- ➔ First, try replacing the batteries.
- If the remote control display remains off when you press the Power button, replace the batteries. If the display still remains off or if the display turns on and off after replacing the batteries, the remote control is malfunctioning and should be replaced.
- You can use the camera app of your phone to check for a malfunctioning remote control. (Certain phone brands and models, such as iPhones, are not suitable for this test.) Turn on your smartphone camera, and point the end of the remote control toward the camera. Press and hold one of the remote control buttons while looking at the phone screen. If you see a light on the phone screen, the remote control is functioning normally and the air conditioner should be inspected for issues.
- ➔ Reset the circuit breaker.
- Locate the breaker switch marked as [Air Conditioner] or [A/C] and switch it on. If the breaker switch for the air conditioner is off (down), the air conditioner will not respond when you press the remote control.
