How To Replace The Frigidaire PureSource3 WF3CB Water Filter:
1. Remove the old filter by pushing on the end/face of the filter.
2. Pull the used filter straight down. (The water shuts off automatically so you don’t have to worry about flooding your refrigerator).
3. Push the new filter straight in until it 'clicks'.
4. If your refrigerator has a 'Change Filter' light, reset it.
How To Reset The 'Change Filter' Light:
1. Press the reset button and hold it down until the green light begins to flash (up to 15 seconds).
For best performance and to ensure clean and safe drinking water it is highly recommended to change your filter every 6 months.
