GE Ice Maker Error Code 2 Blinks

The 2 Blinks code on a GE ice maker indicates a bin thermistor failure. The bin thermistor is the sensor that monitors the ice bin to detect when it is full. The control box has detected that the thermistor circuit is open, shorted, or disconnected, and has stopped the ice-making cycle as a result.

The ice maker will generally not produce ice normally while the 2 Blinks fault is active, because the control box relies on the bin thermistor to determine when to stop a cycle. Continuing to operate it in this state is not recommended, as the machine cannot accurately monitor the bin fill level. It is best to address the fault before resuming regular use.

If the problem is simply a disconnected connector, there is no parts cost involved. If the bin thermistor itself has failed, replacement thermistors for GE ice makers typically range in cost depending on the model and supplier. Adding professional labor, a service call to diagnose and replace the thermistor can range from around 100 dollars to several hundred dollars in total, depending on your location and the technician's rates.

Start by checking that the bin thermistor connector is fully plugged into the control box, as a loose connection is the simplest cause. If the connection is secure, use a multimeter to test the thermistor for continuity and proper resistance. A reading of infinite resistance indicates an open thermistor, and a reading near zero indicates a short. In either case, the thermistor should be replaced. Also inspect the wiring harness for any visible damage.

A reset may temporarily clear the displayed fault, but the 2 Blinks code will return if the underlying problem with the bin thermistor or its wiring is not corrected. The control box will detect the open, shorted, or missing thermistor signal again as soon as it runs its diagnostics. A reset alone is not a fix for this error.
