Most likely causes

  1. Ice jam or stuck cubes locking the ejector
  2. Failed ice maker motor or gear assembly
  3. Wiring or connector fault at the ice maker
  4. Control board not reading the ice maker feedback
Before you start — unplug the refrigerator before working on it. Mind sharp metal edges, and never open the sealed refrigerant system — compressor, sealed-system and refrigerant work must be left to a qualified technician.

Step-by-step fix

1Reset powerUnplug the refrigerator or switch off its breaker for about 5 minutes, then restore power.
2Clear jamsWith the unit off, remove any stuck or clumped ice from the ice maker and bin.
3Run the ice maker testUse the ice maker's reset or test button if equipped and watch whether it completes a cycle.
4Call for serviceIf Er IT persists, the ice maker assembly usually needs a technician to install a replacement kit.

Still showing Er IT?

If you’ve worked through every step and Er IT keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
