Samsung Oven Error Codes
Samsung ranges and wall ovens flash a letter-number fault code the moment the control board sees something out of spec, from a shorted sensor to a stuck key or an overheat lockout. Below are the codes we actually see on the bench, what each one means, and the repair that clears it.
C-20 / C-21
Means: Temperature sensor fault. C-20 flags a shorted or open sensor circuit; C-21 means the oven sensed too high a temperature and locked out for safety.
Fix: Kill power at the breaker for 3 minutes and let the oven cool. If it returns, ohm the oven sensor (roughly 1080 ohms at room temp) and check its harness; replace the sensor if out of range.
C-22
Means: Meat/probe temperature sensor error, or a sensor reading that is short-circuited or out of range.
Fix: Unplug the meat probe and cycle power. If the code stays, inspect the probe jack and wiring, and replace the sensor or probe if the resistance is bad.
C-24
Means: Excessive temperature rise detected inside the oven cavity.
Fix: Clear any vent obstruction, then open and close the door several times or leave it open about a minute to let it cool. If it recurs, suspect the sensor or control board.
C-d0
Means: Stuck key on the membrane touch panel; the board sees a key held down.
Fix: Press each pad firmly to free the stuck key. If it won't clear, the touch/membrane panel or control board needs replacement.
SE / C-d1
Means: Control panel key short or shorted key/touch fault, essentially a failed membrane or touch board.
Fix: Power cycle at the breaker for 3 minutes. If it comes back, replace the touch panel (membrane) or the main control board.
E-08
Means: The oven called for heat and never reached temperature, so the board times out.
Fix: Visually inspect the bake and broil elements for breaks, then check the temperature sensor resistance. Replace the failed element or sensor.
E-0A
Means: Oven overheating: the cavity is running hotter than commanded.
Fix: Unplug and let it cool. Test the temperature sensor; if it reads correctly, the relay control board is sticking heat on and should be replaced.
E-0E / FL
Means: Door lock assembly error, most often after a self-clean cycle.
Fix: Reset power and let it cool fully so the lock releases. If the latch won't cycle, replace the door lock motor/assembly.
LE / E-54
Means: Low-voltage or communication fault between the boards or a voltage problem at the supply.
Fix: Verify the range is on a solid 240V circuit and connections are tight. Reset the breaker for 3 minutes; if it persists, check harnesses and the control boards.
C-F0
Means: Communication error between the control components.
Fix: Reset power at the breaker. On Wi-Fi models, connect to SmartThings and apply any firmware update; otherwise inspect the inter-board wiring.
FAQ
How do I clear a Samsung oven error code?
Cut power at the breaker (or unplug) for at least three full minutes, then restore it. This clears most soft faults; if the code returns immediately, it's a real hardware failure that needs diagnosis.
Which Samsung codes mean it's unsafe to keep using the oven?
Overheat and lockout codes like C-21, C-24 and E-0A indicate the cavity ran too hot. Stop using the oven, let it cool completely, and have the temperature sensor and control board checked before running it again.
