What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
Slow before it stops Ice maker not making ice
No ice, or a bin that never fills. Production halves over weeks before it stops altogether, and almost every cause is cheaper to fix while the machine is still limping along.
- Half the ice it used to make
- Stopped completely after a filter change
- Ice tastes or smells wrong
On the same appliance
What else belongs to the refrigerators
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

What this one means
The ice maker or the controls for the ice and water system have a communication problem.
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- The ice maker module
- The communication between it and the controls
Worth doing before you call
- Cut power at the breaker for thirty seconds
- Check the water filter is the correct one for the model and fully seated
Then what
One of only three codes this manufacturer publishes for its entire US refrigeration line, which is why the refrigerator pages on this site lean on symptoms instead. If you have this one, it is unusually specific.
