If the wireless remote control for your C&H Air Conditioner isn't working, consider these possibilities: The unit might be experiencing interference due to abnormal or frequent function switchovers; in this case, unplug the unit and reinsert the plug. Ensure you are within the receiving range and that there are no obstructions. Check the voltage of the batteries in the remote or replace them. Determine if the remote control itself is damaged.
