What F6 means on a Dacor range oven cooktop

The F6 error code on a Dacor range, oven, or cooktop indicates an EEPROM checksum error. The EEPROM (Electrically Erasable Programmable Read-Only Memory) is a small chip located on the Electronic Range Control (ERC) board that stores critical configuration data, calibration values, and programmed settings for the appliance. A checksum is a numerical value calculated from that stored data and used to verify its integrity. When the control reads the EEPROM and the calculated checksum does not match the expected programmed value, the F6 code is triggered, signaling that the stored data has become corrupted or unreadable.

When this fault is active, the appliance enters a severely limited operating mode. Only the time-of-day clock and the timer functions will continue to work. All cooking functions, bake, broil, convection, and any timed cooking modes, are disabled. This is a built-in protective response to prevent the oven from operating with potentially incorrect calibration or configuration data, which could result in unsafe or inaccurate temperature control.

The most common cause of an EEPROM checksum error is internal corruption of the ERC board itself, often resulting from a power surge, voltage spike, or a momentary power interruption that occurs while data is being written to the chip. Age-related degradation of the EEPROM memory cells can also cause this fault over time. Because the checksum error reflects a problem within the ERC's onboard memory, the recommended corrective action is direct replacement of the ERC unit rather than attempting any repair at the component level.

Common causes of F6

  1. 01

    Failed or Corrupted ERC Board

    Part replacement

    The EEPROM memory on the Electronic Range Control board has lost or corrupted its stored data, causing the checksum verification to fail. This is the primary cause of F6 and requires replacing the ERC.

  2. 02

    Power Surge or Voltage Spike

    Part replacement

    A sudden surge in household electrical supply can corrupt data written to the EEPROM chip on the control board. If the error appeared after a storm, power outage, or utility interruption, a surge event is likely the trigger.

  3. 03

    Power Interruption During Data Write

    Part replacement

    If power is cut to the appliance at the exact moment the control board is writing data to the EEPROM, the stored values can become corrupted and fail the checksum test on the next startup.

  4. 04

    Age-Related EEPROM Degradation

    Part replacement

    EEPROM memory cells have a finite number of read and write cycles. On older appliances, natural wear of the memory chip can cause data retention failures that produce a checksum mismatch.

Frequently asked questions about F6

What does F6 mean on a Dacor range, oven, cooktop?
The F6 code on a Dacor range, oven, or cooktop indicates an EEPROM checksum error on the Electronic Range Control board. It means the control detected that the data stored in its onboard memory chip does not match the expected programmed values. While this fault is active, only the clock and timer will function, and all cooking operations are disabled. Replacing the ERC is the corrective step for this fault.
Can I fix the F6 error on my Dacor appliance myself?
The F6 error requires replacing the Electronic Range Control board, as the fault originates from corrupted memory within that component. A knowledgeable DIYer comfortable working with appliance control boards can perform this replacement, but it does involve disconnecting electrical connectors and handling a live circuit board. If you are uncertain about working with appliance electronics, having a qualified technician perform the repair is the safer choice.
Is it safe to use my Dacor oven when the F6 code is displayed?
When the F6 error is active, the appliance automatically restricts itself to clock and timer operation only, so the heating elements cannot be activated. The oven will not heat in this state, which means there is no immediate safety hazard from the fault itself. However, the appliance should not be considered operational until the ERC is replaced and the error is resolved.
Will resetting the power clear the F6 error on a Dacor oven?
A power reset by cycling the circuit breaker or unplugging the appliance is unlikely to permanently clear the F6 error. Because the fault reflects corrupted data inside the EEPROM chip on the control board, the checksum mismatch will typically return as soon as the control restarts and reads the memory. Replacement of the ERC is the correct resolution.
How much does it cost to fix the F6 error on a Dacor oven?
Repair costs for an F6 error will vary based on the specific ERC part required for your Dacor model and local labor rates. Parts alone for a Dacor ERC board typically range from around 150 dollars to 400 dollars or more depending on the model. Adding professional installation labor, total repair costs commonly fall in the range of 250 dollars to 600 dollars or higher.
