The filter indicator is not trigged via the filter itself. Usually the filter indicator turns on after an amount of water has been dispensed, or after an amount of time. Therefore, changing the filter alone will not reset the filter indicator. To reset the indicator, refer to the manual for your fridge, or contact the manufacturer with the model number of your fridge. Below are the common filter indicator reset instructions. Whirlpool and KitchenAid Press the light switch 5 times within 10 seconds. If the fridge has a filter button, press and hold it for 5-10 seconds. LG Press and hold the reset button for 3 seconds. Maytag Press and hold the lock and light buttons at the same time until the filter indicator flashes (about 4 seconds). On newer models, press and hold the lock and water buttons at the same time until the filter indicator flashes (about 4 seconds). Samsung Press and hold the ICE TYPE and CHILD LOCK buttons for 3 seconds. The water filter indicator should turn green. NOTE: Only hold these buttons for 3 seconds. Holding these buttons for 5 seconds cancels the reset. If you cancel the reset, repeat the procedure.
