GE Ice Maker Error Code ON/OFF LED flashing

The ON/OFF LED flashing indicates that the control board has detected an error in the ice level sensor circuit, specifically the bin thermistor. Because the unit cannot confirm the status of the ice bin, it shuts down ice production entirely to prevent an overflow condition. This fault will keep the ice maker from running until the underlying issue is diagnosed and corrected.

No, the ice maker will not operate when this error is active, so there is no ice being produced regardless. The unit has effectively locked itself out as a protective measure. There is no immediate safety hazard from the fault itself, but you should address the underlying sensor or wiring issue before expecting normal operation to resume.

If the issue is simply a loose connector, the repair costs nothing beyond your time. If the bin thermistor needs replacement, parts typically range from around $20 to $60 depending on the specific model. A control board replacement, if required, can cost considerably more, generally in the range of $80 to $200 or higher for parts alone, with additional labor costs if you use a professional technician.

Start by unplugging the ice maker and removing the cutter grid cover, then locate and firmly reseat the white wiring connector that runs up to the control housing on the right side of the unit. If the error returns after restoring power, the next step is to test the bin thermistor for proper resistance and check the wiring harness for continuity. Depending on what testing reveals, you may need to replace the thermistor, repair the wiring, or in less common cases replace the control board.

A reset may temporarily clear the error code, but if the bin thermistor circuit still has a fault, the flashing LED will return once the control board runs its diagnostic checks again. A reset is not a fix for the underlying problem. The wiring connection, thermistor, and harness need to be inspected and corrected to permanently resolve the fault.
