Model compatibility: GE reuses codes across series and model years, so 0512 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Ice-box thermistor out of range.
Signs
Symptoms you may notice
A harvest cycle may run too long or fail to complete.
Other components may be disabled because the control cannot trust the sensor input.
Temperature-related performance can become inconsistent.
Operation may stop when the control sees an implausible reading.
Why it happens
Possible causes
Wiring damage between the sensor and the main control.
An icemaker thermistor, heater, motor, or position-feedback issue.
A water-supply problem that prevents a normal harvest/fill sequence.
A control problem in the icemaker circuit.
An open, shorted, corroded, or loose sensor connection.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Note whether the code appears immediately or only after heating/cooling begins; that timing is useful for diagnosis.
Remove only loose, accessible ice that the owner’s manual allows you to clear; do not pry the mechanism.
Confirm the household water supply is on if the icemaker fault involves fill.
Check that the ice bucket and user-removable parts are seated normally.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
