Whirlpool refrigerator water filter reset light won't turn off after EveryDrop install? Learn quick fixes to resolve the issue now!
Refer to your refrigerator's user manual or the Whirlpool website, using your model number to find the correct EveryDrop™ filter model. Using an incorrect filter can cause compatibility issues.
Disconnect the power to the refrigerator. Locate the wiring harness connected to the filter head. Using a multimeter set to ohms, test for continuity across the sensor terminals. A reading of open or shorted indicates a faulty sensor.
The MCU is typically located behind the refrigerator, often enclosed in a plastic housing. You may need to remove a rear access panel to locate it. Disconnect power before attempting to access the MCU.
The main control unit (MCU) monitors the water filter status through a sensor in the filter head. This sensor detects the presence and type of filter. When a new filter is installed and the reset button is pressed, the MCU resets a timer. The filter light is triggered by the MCU based on time elapsed, gallons used, or a combination. Voltage paths are typically 5V DC for signaling.
The water filter reset light on the Whirlpool refrigerator remains illuminated even after installing a new EveryDrop™ water filter, indicating that the filter change was not recognized. Water dispensing and ice making may be unaffected.
Disconnect power to the refrigerator at the breaker panel before performing any repairs. Be aware of high voltage circuits within the appliance. Follow Lock-Out/Tag-Out (LOTO) procedures.
Replace the water filter every 6 months or according to the refrigerator's recommendations. Use only genuine EveryDrop™ filters.
Some Whirlpool models have a diagnostic mode. Access it by pressing certain button combinations (refer to the service manual or search online for your specific model). This mode can sometimes force a filter reset.
