What 0604 means on a GE refrigerator

GE error code 0604 is generated by the control board when the French door or freestanding refrigerator's ice maker (FF IM) bucket full sensor continues to report a full condition even after ice has been dispensed. The control board monitors this sensor throughout the dispense cycle and expects the reading to change once ice leaves the bucket. When the signal stays locked in the full state after a completed dispense event, the board flags 0604 and may suspend further ice production to prevent overflow damage.

For a homeowner, this means your refrigerator's ice maker has a sensor that checks whether the ice storage bucket is full. When you dispense ice, that sensor should detect the change in ice level. If it doesn't, the refrigerator thinks the bucket is still packed full and throws this error. In practice, this can mean you stop getting ice even if the bucket is actually empty or partially empty.

The root cause is usually physical ice bridging or jamming over the sensor, a failed bucket full sensor or its associated wiring, or a problem with the ice maker assembly itself. Clearing ice buildup is the first step before replacing any parts, since frost accumulation around the sensor is a frequent culprit in French door models.

Common causes of 0604

  1. 01

    Ice jam or bridging over the bucket full sensor

    Wiring / connection

    Ice can clump or bridge over the optical or mechanical sensor that detects bucket fill level, causing it to read full even after dispensing. This is the most common trigger for 0604 and often resolves with a manual defrost of the ice maker compartment.

  2. 02

    Failed or stuck bucket full sensor

    Part replacement

    The bucket full sensor itself can fail in the closed or triggered position, permanently signaling a full bucket to the control board regardless of actual ice levels. Replacing the sensor or the ice maker assembly is required.

  3. 03

    Damaged or corroded wiring harness to the ice maker sensor

    Part replacement

    The wiring harness connecting the bucket full sensor to the control board can develop a short, open, or corroded connector that holds the sensor signal in the full state. Inspecting and replacing the affected harness segment corrects this.

  4. 04

    Defective ice maker assembly

    Part replacement

    If the sensor and wiring check out correctly, the ice maker module itself may have an internal failure causing it to report erroneous bucket full signals. Replacing the full ice maker assembly is the typical resolution at this point.

Frequently asked questions about 0604

What does error code 0604 mean on a GE refrigerator?
Code 0604 means the ice maker's bucket full sensor is still reading full after ice has been dispensed. The control board expects that sensor signal to change during or after a dispense cycle. When it doesn't change, the board logs 0604 and may halt ice production. Start by checking for ice jams or frost buildup around the sensor before assuming a parts failure.
How do I fix error code 0604 on a GE refrigerator?
Begin by unplugging the refrigerator, removing the ice bucket, and inspecting the bucket full sensor area for clumped or bridged ice. If frost is present, allow the compartment to defrost fully, then restore power and test. If 0604 returns with no ice obstruction, test the sensor's wiring harness for continuity and inspect the connector for corrosion. A failed sensor or ice maker assembly will need to be replaced.
Can I still use my GE refrigerator with a 0604 error active?
The refrigerator's cooling functions will continue operating normally with a 0604 error active. The error is isolated to the ice maker system, so food storage is not compromised. However, ice production will likely be suspended or unreliable until the fault is resolved, so do not count on the ice maker until the underlying sensor or obstruction issue is corrected.
How much does it cost to fix a 0604 error on a GE refrigerator?
If the fix is simply clearing an ice jam or frost buildup, the cost is nothing beyond your time. A replacement bucket full sensor or ice maker wiring harness typically runs between $15 and $50 in parts. A full ice maker assembly replacement can cost $80 to $200 in parts depending on the model. Professional labor adds $100 to $200 on top of parts if you hire a technician.
Will resetting my GE refrigerator clear the 0604 error code?
A reset by unplugging the unit for 30 seconds may temporarily clear the code, but if the underlying cause is a failed sensor, ice jam, or wiring fault, 0604 will return once the ice maker runs through another cycle. A reset is useful for confirming whether the fault is intermittent or persistent, but it does not fix the sensor or obstruction responsible for the code.
