Samsung Oven Error Code C-F1 — EEPROM Read/Write Error
What this means
The C-F1 error code indicates the EEPROM (electrically erasable programmable read-only memory) on the oven's electronic control board has failed to read or write data properly. The EEPROM stores cycle settings, calibration data, and operating parameters. This is typically a control board failure, though it can sometimes be resolved by a power cycle if the data was corrupted by a power surge.
Alternate codes: CF1
Step-by-step fix
3 stepsPower cycle the oven
Turn off the circuit breaker for 10 minutes, then turn it back on. If the EEPROM was temporarily corrupted by a power surge, a full reset may clear the error.
This fix is most likely to work if the error appeared after a power outage or storm.
Check wire connections to the control board
Unplug the oven and access the electronic control board (usually behind the control panel or rear cover). Check that all wire harness connectors are firmly seated.
A loose connector can sometimes cause read/write errors.
Replace the electronic control board
If the error persists, the control board needs replacement. Photograph all connections, disconnect the wire harnesses, remove the old board, install the new board, and reconnect everything.
Some replacement boards may need oven temperature calibration after installation.
When to call a professional
Control board replacement and calibration is best handled by a qualified technician, especially if the oven requires temperature calibration after board replacement.
