Whirlpool EveryDrop™ Water Filter Reset Light Stuck ON:... | appliancefaults.com

Technical Background:

The refrigerator's main control unit (MCU) monitors the water filter usage via a microswitch in the filter head. When the filter is replaced, the switch closes, signaling the MCU to reset the filter timer. The dispenser control board interprets these signals and controls the indicator lights. Voltage paths range from 5V DC to 12V DC.

Symptoms:

The water filter reset light on your Whirlpool refrigerator remains illuminated even after replacing the water filter. Pressing the reset button has no effect.

Possible Causes:

Faulty water filter microswitch.
Defective dispenser control board.
Wiring harness issue between the filter head and the control board.
Software glitch in the main control unit (MCU).
Incorrect filter system.
Clogged water filter head assembly.

Solution:

1

Disconnect power to the refrigerator at the breaker panel.
2

Verify correct filter system. Remove and re-install the water filter, ensuring it clicks into place.
3

Inspect the water filter head microswitch. Use a multimeter to check continuity when the filter is inserted and removed. Replace if faulty. A normal closed (NC) switch should open when the filter pushes the actuator.
4

Check the wiring harness from the filter head to the dispenser control board for damage or loose connections. Repair or replace as needed.
5

Examine the dispenser control board for visible signs of damage, such as burnt components. Replace the board if necessary.
6

Attempt a hard reset. Unplug the refrigerator for 5 minutes to clear the MCU's memory.
7

As a last resort, consider a main control board replacement. Back up all settings before replacement, if possible.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs. Follow Lock-Out/Tag-Out (LOTO) procedures. Some components may carry 120V AC.

Prevention:

Replace the water filter according to the manufacturer's recommended schedule (typically every 6 months). Periodically inspect the filter head area for leaks or damage.

Expert Tip:

Some Whirlpool refrigerators have a service mode. Consult the technical sheet for your specific model to access service mode and perform a forced filter reset.

Frequently Asked Questions

•Where is the water filter microswitch located?

The water filter microswitch is usually integrated into the water filter head assembly. It's activated when the water filter is correctly installed.

•How do I test the dispenser control board?

Testing the dispenser control board requires a multimeter and the refrigerator's wiring diagram. Check for proper voltage readings at the input and output terminals. Specific tests depend on the board's function.

•What is the part number for the dispenser control board?

The part number for the dispenser control board varies depending on the specific Whirlpool refrigerator model. Consult the refrigerator's parts diagram or the model number to find the correct replacement part.
