Samsung Range C-F1 — What It Means & How to Fix It
Also shown as CF1 on some models.
C-F1 is the EEPROM read/write fault: it only occurs while the oven is reading or writing its memory settings. Samsung's fix is a restart, then a 30-second power off.
What this code means
C-F1 is the EEPROM read/write fault. Samsung's official page defines it in one line: it only occurs during EEPROM read/write — the oven's stored settings memory being read or written. When a read or write glitches, the control shows C-F1 rather than trust a possibly corrupt setting. Samsung's fix is the standard two-step: turn the oven off and restart it, and if the code continues, switch the power off for 30 seconds or more and then reconnect.
Samsung's official information-code page lists C-F1 with the meaning 'only occurs during EEPROM read/write' and the restart-then-30-second-power-off resolution. The model number is on the frame behind the storage drawer.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| One-off memory read/write glitch | Common | Yes — restart and power off |
| Corrupted stored settings after a power event | Common | Yes — power off 30 seconds |
| Control board memory fault | Occasional | No — technician job |
| Loose control-board connection | Less common | No — technician job |
What you can try yourself
- Turn the oven off and restart it — Samsung's own first step for C-F1.
- If the code continues, switch the power off for 30 seconds or more, then reconnect it.
- Re-enter any custom settings (clock, temperature offset) once the oven is back on, since memory read/write was the part that faulted.
- A C-F1 that returns after the routine points at the control board's memory — a technician's diagnosis.
When to call a technician
- C-F1 returns every restart, or the oven forgets settings repeatedly.
- The display shows corrupted characters or freezes on boot.
- The code appears together with other control-family faults.
Typical professional repair cost: No cost if a reset clears it; a control-board repair or replacement typically runs $200–$450 including labor.
Frequently asked questions
What is EEPROM on my range?
It's the small non-volatile memory chip on the control board that holds your stored settings — clock, offset, user preferences. C-F1 names a problem while that memory is being read or written.
Will a C-F1 clear by itself?
Often yes after the official routine — restart, then 30 seconds of power off — especially when a power event corrupted a single settings write. Samsung's page gives that exact sequence.
Do I lose settings after clearing C-F1?
Possibly — the memory being rewritten may revert to defaults. Re-entering the clock and any small preferences is worth doing after the power-off step.
