FFIM water tube keeps forming ice plug. I can break out the plug and ice maker resumes normal operation for about a week until it plugs again. Ran diagnostic mode on ice maker and everything seems to be normal.
The ice maker was replaced because the old ice maker thermistor broke off the bottom and shorted out the board. Replaced main board and ice maker and have had this problem ever since.

Hello
If it the the water inlet supply tube freezing up you have two possibilities.
1) The water inlet valve when not energized is leaking through due to a defective plunger assembly. When a small amount of water is leaking through the inlet valve it will form ice in the inlet tube.
2) Frozen Freezer IM Fill Tube on French Door Non-Dispenser/Dual-Ready Models
Solution: Replace freezer ice maker fill tube with kit 5303918600. This kit contains an improved fill tube.
When the new fill tube is installed, the connecting water line must be shortened by 2-2.5” to prevent kinking.
Foam pad needs to be placed on the tube only if it was present on the original tube in the unit.
Also, investigate sealing of the air duct to the liner. Air leak in this area can contribute to freezing of the fill tube.
Use kit 5303918479 if needed to improve seal.
