Dacor Range Error Code F5

The F5 code on a Dacor range indicates that the ERC, or Electronic Range Control, has failed its own internal self-diagnostic check. This means the main control board has detected a fault within its own circuitry and is reporting itself as defective. The range will typically stop functioning normally when this code appears. Replacing the ERC is the recommended corrective action.

It is not recommended to continue using the range while an F5 code is active. The ERC controls critical functions including temperature regulation and element shutoff, and a failed control board can lead to unpredictable operation. Discontinue use of the range until the ERC has been replaced and the fault is cleared.

Resetting the range by cutting power at the breaker or unplugging the unit for several minutes is worth attempting, but it rarely clears a true F5 fault. Because F5 is generated by the ERC's own self-diagnostic routine detecting an internal board failure, the code will typically return immediately once power is restored. A persistent F5 code after a reset confirms that the ERC board needs to be replaced.

A homeowner with intermediate DIY skills can attempt to replace the ERC board, but the repair involves working with line voltage components and is best handled by a qualified technician. Before ordering a replacement board, try disconnecting power to the range for a few minutes to see if the error clears, though this rarely resolves an F5 fault. If the code returns immediately after restoring power, the ERC board will need to be replaced.

The cost to repair an F5 error on a Dacor range depends primarily on the price of the replacement ERC board and the cost of labor if a technician is hired. ERC boards for Dacor ranges typically range from $150 to $400 or more depending on the model, and professional labor can add $100 to $200 on top of that. Getting a repair estimate before proceeding is advisable, especially on older units where the repair cost may approach the value of the appliance.
