Understanding CF Code: Filter Cleaning Reminder❓

The CF code stands for "Clean Filter" and is a reminder rather than a malfunction or fault. It typically appears on the display panel of your refrigerator after a preset number of hours or months of use, indicating that the air or water filter needs cleaning or replacement. The filter plays a key role in maintaining air quality and water purity, and ignoring this reminder can lead to poor cooling performance, odors, or reduced water flow.
