Can't identify "water filter indicator light"

It could be a couple of resons, I have the same problem. With my refrigator its the water tube that fills the tray freeze up. So I have to shut off the unit, leave the freezer door open for about 30 minutes or so. Then restart the unit.

Is the ice maker working ? If so , the filter is not the problem . At the bottom of the freezer door ( remove the kick plate ) , there will be a water line . Follow this line , about 6 " to a connector . Push in on the white ring and pull out the line , at the same time . Activate the water dispensor pad and see if water flows from the line under the refrig . If it does , then the line in the door is frozen . Either raise the freezer temp for several days , so the line in the door will thaw , or , I have heard using an air tank will blow the ice out of the line in the door . If no water comes from the line under the refrig , while activating the pad , then replace the water valve , behind the refrig , the piece the wall water line connects to on the refrig .

There is also a dispensor heater , you may want to install , pt # WR49X10173 . This should keep the water line from freezing again , if it turns out to be that problem .

Replace the water valve behind refrig , where the wall water line connects to on refrig .

ck condensor fan motor that cools compressor under unit. yoder loop runs through center divider and causes gaskets to get hot

1) remove the tubing connector behind refrig kickplate . Press for water . If no water comes from tube under refrig , then possibly frozen tank but probably not . Probably bad water inlet valve . ( tank is in the lower potrion of the refrig section behind the crispers ) .
2) if water does shoot out , then your freezer door is frozen which requires leaving door open and tapeing light switch closed and tape plastic around freezer section opening so fridge will continue to operate normally . Thawing freezer door could take a day or 2 . 3) You can plug the hoses back togather and walk by occasionally pressing water untill comes out . Lower your freezer temperature setting also ( could be set for too cold)

If this is the Kenmore french door model with bottom freezer and ice and water in the door made by LG it could be that the mother board has failed.  Call for service and hope that warranty is still in effect.

This is an error code for the icemaker fan motor.
If the control does not see a signal coming back from the fan motor you will get this error code.
Please see the image below from the service manual that explains the ER IF error code.

The ER IF code indicates a failure of the icing fan.

You may notice slower ice production but the other fans should be okay.

You can select the ultra ice option and see if the fan toggles on.

The fan or the control is bad.

1) Electric Water valve check up.
2) Water/Ice dispenser control check up
3) frozen plastic pipe inside door or/and chilled water container frozen
4) old water filter (clogged)

This sounds like the Maytag bottom mount that has a High Voltage Control Board problem. Does this have the freezer/fridge temp. display/controls on the left hand fridge door? Whats the model number and on the manufacture tag does it something on it like Code:0304 maybe? Let me know I may have an answer I do work on these for a living.
