I just replaced the water inlet valve on this fridge (i'm not 100% sure the last 4 letters on the model are the same - mine just has gsh25sg on it). The ice maker inlet tube is still freezing over, but when i cleared it and checked for drips it was not dripping so the inlet valve seems to be working correctly.
i noticed there is wiring and a plate surrounding the metal ice maker feed tube. is this plate supposed to heat up to melt the ice in the feed tube? if so, what part needs to be replaced to ensure that is working?
Answer We normally wouldn't recommend you just replace a part, without testing it first especially an expensive part WR23X10257 like this, it's basically most of the freezer compartment wiring harness. You're pretty much on target, the part you're describing is usually referred to as an ice maker fill tube heater, It cycles off and on with the defrost cycle to maintain a free and open fill tube. If you can access a multi meter and disconnect the wires and check across the two wires from the heater for a "closed" circuit, you could save a bit of money and move on to other possible issues. There could be an air leak around the doors, or the dispenser door flapper may not be seating and sealing properly or the freezer could be set too cold (you want an average temperature in the freezer of 3 to 5 dgrs to maintain an average of 0 dgrs, or even warmer depending on the usage.With a new fill valve we'd expect the issue to be remedied especially since there isn't any drips, but there could be "flash freezing" in the tube due to too low a temperature.
My icemaker makes ice cubes, but the in door water dispenser does not dispense water. I checked the water inlet valve at the back of the unit for power. It has power. It makes a humming noise when trying to dispense water.. This happened suddenly without warning.
You will want to remove the kickplate, make sure that you have a towel handy, and disconnect the water line at the bottom of the door. Once you disconnect, make sure that the dispenser is set for water, hold the tubing that is coming from under the unit and push the lever on the door for water. If water comes out of the tube then the dispenser water fill tube is frozen and the only way to correct this would be to replace the outer door.
