GE Ice Maker Error Code 2 Blinks

Bin thermistor failure

GE codesGE ice maker codes

Bin thermistor failure — the bin thermistor is open or shorted, or disconnected from the control box.

First step from the service manual

Check that the bin thermistor is plugged in to the control box. Check that the bin thermistor is not open or shorted. Replace the thermistor if it is open or shorted.

What 2 Blinks means on a GE ice maker

The 2 Blinks error code on a GE ice maker indicates a bin thermistor failure. The bin thermistor is a temperature-sensing component that monitors the ice bin to detect when it is full of ice. The control box uses resistance readings from this thermistor to determine bin status and regulate the ice-making cycle. When the control detects that the thermistor circuit is open, shorted, or not electrically connected, it halts operation and signals the fault with 2 blinks.

An open thermistor means the internal resistive element has broken, resulting in no continuity through the sensor. A shorted thermistor means the resistance has collapsed to near zero, causing the control to read an invalid temperature signal. Either condition prevents the bin thermistor from sending accurate data to the control board. In both cases, the ice maker cannot reliably determine when the bin is full, which makes continued operation unreliable or unsafe.

The most straightforward cause to rule out first is a loose or disconnected wiring connection between the thermistor and the control box. Vibration during shipping or normal use can dislodge connectors. If the connector is secure, the thermistor itself should be tested for proper resistance. A thermistor reading that is infinite (open) or near zero (shorted) confirms the sensor has failed and requires replacement. The wiring harness between the thermistor and control box should also be inspected for pinching, chafing, or corrosion that could cause an intermittent or permanent fault.

Common causes of 2 Blinks

  1. 01

    Disconnected bin thermistor connector

    Wiring / connection

    The thermistor plug may have come loose from the control box due to vibration or handling. Inspect the connector at the control box and reseat it firmly.

  2. 02

    Failed bin thermistor (open circuit)

    Part replacement

    The resistive element inside the thermistor can break, resulting in infinite resistance when tested with a multimeter. A reading of infinite resistance confirms the thermistor is open and must be replaced.

  3. 03

    Shorted bin thermistor

    Part replacement

    Internal failure of the thermistor can cause it to short, dropping resistance to near zero. This produces an invalid signal that the control board cannot use, triggering the 2 Blinks fault.

  4. 04

    Damaged wiring harness

    Wiring / connection

    The wiring between the bin thermistor and the control box may be pinched, chafed, or corroded, causing an open or short in the circuit without the thermistor itself being defective. Visually inspect the harness along its entire length.

  5. 05

    Faulty control box

    Part replacement

    If the thermistor tests within normal resistance range and the wiring is intact, the control box input circuit may have failed. This is the least common cause and should only be considered after the thermistor and wiring are confirmed good.

Frequently asked questions about 2 Blinks

What does 2 Blinks mean on a GE ice_maker?
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.
How do I fix the 2 Blinks error on my GE ice maker?
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.
Is it safe to keep using my GE ice maker when it shows the 2 Blinks error?
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.
Will resetting my GE ice maker clear the 2 Blinks error code?
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.
How much does it cost to repair a GE ice maker showing the 2 Blinks error?
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.
