Samsung Oven Error Codes: C-d0, C-F0 and -dC-

Quick answer: Samsung oven codes often start with C-: C-d0 is a button problem, C-d1 a door lock fault, C-20 to C-22 sensor faults, C-F0 a communication error and C-24 a blocked vent. Some codes, like -dC- for the partition, are fixed by adjusting the oven rather than repairing it.

Samsung ranges and wall ovens show codes in the oven display. Codes vary by model and by the country the oven was sold in, so the list below sticks to codes Samsung documents. For any code not listed, Samsung's advice is to turn the range off and back on with the Power button, then, if the code returns, switch off the circuit breaker for 30 seconds. If you ever smell gas, do not touch any switches or the oven controls. Leave the home right away and call your gas utility from outside.

Samsung Oven Error Codes list

C-d0

Button problem: a key was detected as pressed and held.

Common causes: Moisture, grease or a stuck key on the touch panel.

What you can try: Wipe the panel dry, turn the oven off and try again.

Call a technician if: The code returns. The touch panel may need service.

C-d1

Door lock malfunction.

Common causes: Lock motor, latch or switch fault.

What you can try: Turn off and restart. If it continues, switch off power for 30 seconds or more.

Call a technician if: The code returns or the door will not lock or unlock.

C-20 / C-21 / C-22

Temperature sensor malfunction.

Common causes: Failed sensor or wiring.

What you can try: Turn off and restart, then cut power for 30 seconds if needed.

Call a technician if: The code returns.

C-24

Oven temperature is rising faster than normal, usually from a blocked vent.

Common causes: A pan or object covering the vent on the back of the cooktop.

What you can try: Clear the vent. Open and close the door a few times, or turn the oven off and leave the door open for a minute to cool.

Call a technician if: The vent is clear and it keeps happening.

C-F0

Communication error between electronic boards.

Common causes: Loose connection, board fault or software.

What you can try: Power reset. On some induction models, Samsung offers a software update through SmartThings.

Call a technician if: The code persists after a reset or update.

C-10

Shown during a SmartThings self-check when the oven starts very hot or very cold.

Common causes: A sensor limit during testing, not a defect.

What you can try: Ignore it if the oven heats normally.

Call a technician if: It appears on its own during cooking.

-dE- / -dC-

The oven partition (divider) is not installed properly for Twin or Dual cooking.

Common causes: Divider missing, half-inserted or inserted mid-cook.

What you can try: Push the divider fully into the correct rack position (third from the top on electric and dual-fuel models, fourth on gas), or make sure nothing presses the switch at the back.

Call a technician if: The divider is seated and the code remains.

door

The door is not closed, or the sensor does not register it.

Common causes: Stuck door plunger or misaligned door.

What you can try: Check that the round black plunger at the door frame moves freely and the door closes fully.

Call a technician if: The code shows with the door shut.

CtoP

Self Clean was started while a burner or element was on.

Common causes: Cooktop in use.

What you can try: Turn off all burners and elements, then start Self Clean.

Call a technician if: Not needed.

tESt / tE5t

Demo mode is on and the oven will not heat.

Common causes: Demo mode activated.

What you can try: Turn off Demo mode using the steps in your manual. Note that gas burners still light in Demo mode.

Call a technician if: It cannot be turned off.

bAd LinE

The power connection is not wired properly.

Common causes: Installation wiring error.

What you can try: Do not use the range.

Call a technician if: An installer or electrician needs to correct the connection.

How to clear the code

Press Power to turn the range off, then back on.
If the code returns, switch off the circuit breaker for 30 seconds, then turn it back on.
If the code still returns, the oven needs service.

Gas and dual-fuel safety

On Samsung gas and dual-fuel ranges, an electronic fault can affect ignition. Do not light the oven manually or open the cooktop or valve area. If you smell gas, get everyone out of the home and call your gas utility from outside. Any repair involving gas connections or valves is a job for a qualified technician.

FAQs

What does C-d0 mean on a Samsung oven?

C-d0 means the control detected a button pressed and held. Wipe the touch panel clean and dry, turn the oven off and try again. If it keeps returning, the panel needs service.

What does -dC- mean on a Samsung range?

It means the oven partition is not seated correctly for Dual or Twin cooking. Remove it and push it fully into the correct rack position, or take it out if you are cooking in single mode.

How do I fix C-24 on my Samsung range?

C-24 usually means the vent on the back of the cooktop is covered, often by a pan. Clear the vent and let the oven cool by opening the door briefly.

Codes and meanings vary by model and model year. Check your owner's manual for your exact model.
