GE Refrigerator Error Code 24

Error code 24 on a GE refrigerator indicates the ice tray sensor is reading a resistance greater than 45K ohms, which is outside the normal operating range. The control module flags this condition as the sensor being abnormally cold or as a potential open circuit. This fault can disrupt the ice maker's harvest cycle because the board cannot accurately determine ice tray temperature. Diagnosing it starts with checking the sensor's connector at the module and measuring the sensor's resistance directly.

A power reset may temporarily clear the error code display, but if the underlying fault is still present, the code will return once the control module re-evaluates the sensor circuit. Resetting is useful as a quick check after reseating a connector, but it does not substitute for actual diagnosis and repair of the sensor or wiring.

If the fix is simply reseating a loose connector, there is no parts cost involved. If the ice tray thermistor needs to be replaced, parts typically range from $15 to $50 depending on the model, and a professional technician's labor for this repair generally adds $75 to $150 to that total. Costs will be higher if the wiring harness or control module is also damaged.

A knowledgeable DIYer can start by unplugging the refrigerator, locating the ice tray sensor connector at the control module, and inspecting it for looseness or corrosion. Reseating a loose connector sometimes clears the fault without any parts. If the sensor itself measures above 45K ohms at room temperature, replacing the thermistor is a straightforward repair, though it does require identifying the correct replacement part for your specific model.

Error code 24 is primarily a functional issue affecting the ice maker rather than a safety hazard. The refrigerator's cooling system for food storage typically continues to operate normally. However, leaving the fault unaddressed means ice production will be unreliable or may stop entirely.
