What Does Error Code dC Mean on a Samsung Oven?

Divider/partition check needed (Flex Duo / Dual Cook models).

The control board reads a partition/divider switch at the rear of the cavity to confirm whether the divider is installed. dC (or dE) fires when the selected mode's required divider state doesn't match what the switch senses — for example, a Dual Cook mode expects the divider seated but it is missing or not fully engaged. Unlike a true door fault, this is a configuration prompt: the oven halts to prevent running an upper/lower zone without the partition properly positioned.

Models affected: Samsung Flex Duo / Dual Cook ranges and wall ovens (for example the NX58R5601SS); other single-cavity models without a divider do not use this code
What owners report: Owners commonly see this right after removing the divider for a large item or after cleaning, when the panel is bumped or not clicked fully into its rack slots. The usual quick win is reseating the divider on both sides and power-cycling; if it lingers with the divider clearly in place, something is likely pressing on or fouling the rear partition switch.

What Causes Error Code dC?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Divider removed during Dual/Twin cook 45% of cases
  2. 2
    Divider not seated in the correct rack position 35% of cases
  3. 3

  4. 4
    Partition switch fault 5% of cases

🔧 Easy DIY Est. time: 10–20 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Reinstall the divider correctly

    Seat the partition fully — each side in the correct rack position for your model (electric/dual fuel vs gas).

    ⚠️ Let the oven cool before reaching inside.
  2. 2

    Check the partition switch

    If no divider is in use, make sure nothing presses on the partition switch at the back of the cavity.

  3. 3

    Power cycle the oven

    Turn off the power for 30 seconds or more and restart.

How to Reset Error Code dC

Reinstall the divider correctly (or clear the partition switch) and restart.

Frequently Asked Questions

Can I keep using my Samsung Oven when error dC appears? +
Usually yes — dC is a low-severity door notice that rarely stops the oven from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes dC on a Samsung Oven? +
Across reported Samsung oven repairs, the most frequent is divider removed during Dual/Twin cook (45% of cases), divider not seated in the correct rack position (35%), then partition switch obstructed at the back of the cavity (15%). Check them in that order before replacing any parts.
dC keeps coming back after a reset — what should I check next? +
A reset only clears the stored dC fault; if it returns, the door problem is still present. Move on to the physical checks — reinstall the divider correctly, then check the partition switch — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Samsung Oven error dC? +
A DIY repair typically runs $0–$0 in parts, versus $120–$250 for a professional service call, so handling it yourself saves around $120. Expect the work to take about 10–20 minutes.
Which Samsung Oven models show error dC? +
dC is documented on Samsung Flex Duo / Dual Cook ranges and wall ovens (for example the NX58R5601SS); other single-cavity models without a divider do not use this code. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
