GE Refrigerator Error Code F404

F404 indicates a Main Board Hardware Failure on a GE refrigerator. The main control board has detected an internal fault within its own hardware components. This is not a sensor or wiring issue. The main control board must be replaced to resolve this error.

No, a reset will not clear the F404 error permanently. Because the code indicates a hardware-level failure within the main board itself, the board will continue to detect and report the same fault after any reset. The only resolution is replacing the main control board.

The cost to resolve an F404 error depends on the main board part cost and whether you hire a technician. Main control boards for GE refrigerators typically range from $100 to $300 or more depending on the model. Adding professional labor, total repair costs generally fall in the range of $200 to $500. Getting a repair estimate before committing is advisable, especially on older units.

The fix for F404 is replacement of the main control board. A knowledgeable DIYer comfortable with disconnecting power, accessing the board location, and transferring wiring harness connectors can perform this replacement. However, if you are not comfortable working with appliance electronics, hiring a certified appliance technician is the safer option.

Continuing to run the refrigerator with an F404 error is not recommended. A compromised main control board may not reliably manage compressor cycles, fan motors, or defrost functions, which can lead to inconsistent temperatures and food spoilage. There is also a risk of secondary component damage from an improperly functioning control board.
