Whirlpool Refrigerator: Water Filter Reset Light Stays... | appliancefaults.com

Technical Background:

The refrigerator's main control unit (MCU) monitors the water filter's status. Typically, a reed switch inside the water filter housing senses the presence of the filter. When a new filter is installed, the MCU recognizes the change and resets the filter life timer. The filter reset light is triggered by a signal from the MCU. Voltage paths may include 5V DC signals from the control board to the filter head.

Symptoms:

The water filter reset light on your Whirlpool refrigerator stays on even after you have replaced the water filter with a new EveryDrop filter. Pressing the reset button does not turn the light off.

Possible Causes:

Faulty water filter
Incorrect filter system
Defective water filter head
Stuck or shorted reed switch in the filter housing
Control board malfunction
Software glitch

Solution:

1

Remove and Reinstall the Water Filter: Ensure the EveryDrop filter is the correct model and is properly seated and locked into the filter head. Make sure it clicks.
2

Cycle Power to the Refrigerator: Unplug the refrigerator from the outlet for 5 minutes to reset the control board. Plug it back in and check if the light turns off.
3

Check the Water Filter Head: Inspect the filter head for any visible damage or debris. Clean the filter head with a damp cloth.
4

Manually Reset the Filter Light: Press and hold the water filter reset button for 3-5 seconds. Refer to your owner's manual for the exact location of the reset button.
5

Test the Reed Switch (if accessible): Use a multimeter set to continuity to test the reed switch. The switch should be closed (continuity) when the filter is installed and open (no continuity) when the filter is removed. The switch is usually behind the filter housing; you might need to remove the housing to access it. If the switch fails, you likely need a new filter head assembly.
6

Inspect Wiring to the Filter Head: Check the wiring harness connecting to the filter head. Look for any loose connections, damaged wires, or corrosion. Repair or replace as needed.
7

Control Board Replacement (If all else fails): If none of the above steps resolve the issue, the control board might be defective. Replacing the control board is a more complex repair that may require licensed technician assistance. Be sure to disconnect power before replacing the board.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Lock-out/Tag-out (LOTO) procedures should be followed. Some components may carry 120V AC.

Prevention:

Replace the water filter every 6 months or as recommended by the manufacturer. Use only genuine EveryDrop filters. Avoid forcing the filter into the head.

Expert Tip:

Some Whirlpool refrigerators have a service mode that allows you to manually reset the filter timer through the control panel. Consult the service manual for the specific model for instructions.

Frequently Asked Questions

•How do I access the service mode on my Whirlpool refrigerator?

The service mode sequence varies depending on the model. You will typically need to press a specific combination of buttons on the control panel within a short time frame. Consult the service manual for your specific refrigerator model for the correct sequence.

•What voltage should I expect to see at the reed switch connector?

You should typically see around 5V DC at the reed switch connector when the refrigerator is powered on. This voltage is used to signal the control board when the filter is present.

•Where can I find a replacement water filter head for my Whirlpool refrigerator?

You can purchase a replacement water filter head from appliance parts retailers, online marketplaces like Amazon or eBay, or directly from Whirlpool's website. Be sure to have your refrigerator's model number handy to ensure you get the correct part.
