If your Haier portable AC unit displays a blinking red light, there’s a high chance that it experiences a full water tray. It won’t be able to operate until you drain all the water. To perform this task, pull the small black tube with a plug under the unit. Tip it down carefully and drain the water as much as possible. After you’ve drained the water tray, set back the plug-in and activate the unit again.
