GE Range Error Code F820

The F820 code on a GE range indicates a memory error on the main logic board, specifically within the EEPROM chip that stores the range's operating data and configuration settings. The control system has detected that this memory is corrupted or unreadable. This fault requires replacement of the main logic board to resolve.

It is not recommended to continue using the range while the F820 error is active. A corrupted main logic board memory can cause unpredictable control behavior, meaning the range may not respond correctly to input or may not regulate temperatures accurately. Discontinue use until the board has been replaced.

The cost to resolve an F820 error depends on the specific range model and labor rates in your area. Main logic board parts typically range from around $150 to $350 or more, and professional labor can add $100 to $200 on top of that. Getting a repair estimate before proceeding is a good idea, as total costs can sometimes approach the value of an older range.

The F820 error requires replacing the main logic board, which involves working with electrical components and disconnecting power safely. While a skilled DIYer comfortable with appliance repair may be able to complete the board swap, most homeowners will benefit from having a qualified technician handle the repair to avoid injury or further damage to the range.

A power reset, such as unplugging the range or cycling the circuit breaker, may temporarily clear the F820 code, but it will return because the underlying EEPROM fault on the main logic board is a hardware failure. A reset does not repair corrupted or failed memory, so board replacement is still required for a permanent fix.
