For the Samsung Oven & Range families covered by the source set, **C-F1** means **eeprom read/write error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **C-F1**. Search normalization stores it as **CF1** while preserving the characters a homeowner actually sees.

Quick answer
EEPROM read/write error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so CF1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
For the Samsung Oven & Range families covered by the source set, **C-F1** means **eeprom read/write error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. The exact stage when the code appears can be as important as the characters themselves.

Signs
Symptoms you may notice
When the C-F1 condition is present, the appliance can lose communication between control boards, display, inverter, or other electronic modules.
Depending on the exact model, controls can become unresponsive, a feature can stop, or the code may appear after power-up.
When the C-F1 condition is present, intermittent operation can occur if a connection or power condition is unstable.
Depending on the exact model, c-F1 appears on the range/oven and the related cooking, sensing, door, or control function may be limited.
Why it happens
Possible causes

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
A safe owner-level check is to power the appliance off once using the documented method, then restore power and see whether the code returns.
Before opening any service area, record whether the issue followed an outage, update, move, or service event.
A safe owner-level check is to do not reseat internal live connectors unless qualified to follow the exact service procedure.
Before opening any service area, record the exact code and model number.
The next non-invasive check is to check door/divider/pan placement, vent obstruction, settings, and household power only when relevant.
Before opening any service area, do not perform live high-voltage internal testing; request service if the code reappears.
Important safety warning. When working around an oven or range that shows C-F1, keep the checks external and non-invasive. Stop for arcing, repeated breaker trips, uncontrolled heating, damaged wiring, or gas odor. Internal live-voltage and gas-system diagnosis is not a homeowner check.

When to request repair service
A returning communication/electronic-control code can require harness, connector, board power-supply, firmware, or module testing. In a service visit for C-F1, model-specific testing should follow the eeprom read/write error circuit rather than treating the code as proof of one failed part.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **C-F1** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **C-F1** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **C-F1** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Oven & Range C-F1** separate from same-looking codes used by other Samsung appliance families.
