Samsung Range and Oven Error Codes: What They Mean and How to Fix Them
What C-24, C-F0 and tESt mean on a Samsung electric range or wall oven, which ones you can clear yourself and which need a technician.
When a Samsung range or wall oven shows a code such as C-24, C-F0 or tESt, it is the control board telling you what it noticed. Many of these codes are information messages and clear with a simple power reset. Others point to a door switch, a sensor or a communication fault that needs a technician.
Codes differ between models and model years, so start by finding your model number. On a freestanding range it is usually on a label on the frame around the oven opening or inside the oven door edge; on a wall oven it is usually on the frame inside the door. This guide covers electric ranges and wall ovens, and a few codes are marked where they come from Samsung's UK documentation instead.
Never remove the back panel or pull the range out to look at wiring. Resetting the power at the Power button or the breaker is the only electrical step this guide suggests.
This guide is for electric ranges and wall ovens. If you smell gas, leave the area and call your gas supplier; gas appliances must be handled by a licensed gas technician.
Mode and information codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| tESt (tE5t) | Range is in demo mode | Turn demo mode off using your user manual | If demo mode will not switch off |
| C-10 | Sensor reading during a SmartThings self diagnosis | Ignore it if the oven heats normally | If it appears on its own during cooking |
| Pr E | Oven is preheating, which is normal | Keep the door closed until it disappears | Not a fault |
Samsung range tESt (tE5t) error
tESt (sometimes shown as tE5t) means the range is in demo mode, the display setting used on showroom floors. In this mode the oven and cooktop will not heat, so nothing is actually broken. The steps to turn demo mode off depend on the model, so follow the instructions in your user manual. If you cannot get out of demo mode, a technician can sort it out.
Model note: The exit steps for demo mode are model specific. Samsung points owners to the user manual for their model.
Samsung range C-10 error
C-10 can show up when you run a self diagnosis from the SmartThings app, especially if the oven starts the test very cold or very hot. In that situation it is a limit of the sensor and not a real fault, and you can ignore it if the oven heats normally. If it appears by itself during normal cooking, try a power reset. If it keeps coming back, book a technician.
Samsung range Pr E error
Pr E is not an error. It simply tells you the oven is still heating up to the temperature you set. It disappears by itself once the oven reaches that temperature, and keeping the door closed helps it get there sooner.
Model note: This entry comes from Samsung's UK oven guide. North American models may display preheating differently.
Code keeps coming back? Book an oven, stove & range repair and tell us the code and your model number.
Door and divider codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| door | Oven thinks the door is not closed | Make sure the door closes fully | If it shows with the door closed |
| dC (dE, -dE-, -dC-) | Divider is missing or not seated | Check the divider is installed correctly | If it persists with the divider correctly in place |
Samsung range door error
The door message means the range does not detect a fully closed door. First check that the door shuts all the way and that nothing is holding it open. If the code stays on with the door properly closed, the door switch may be at fault, and that is a job for a technician.
Samsung range dC (dE, -dE-, -dC-) error
dC and dE relate to the divider (partition) used by models with a dual cook or twin mode. The code appears when the divider is not installed properly, or when cooking was started before it was put in. Remove the divider and push it fully back into place, or take it out completely if you want to use the oven as a single cavity. If the code stays, book a technician.
Model note: Only applies to models that come with a divider. Samsung's UK guide describes the same codes as a divider check and says to turn the oven off and restart it.
Temperature and sensor codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| C-24 | Oven temperature rising faster than normal | Clear anything covering the vent at the back of the cooktop | If it returns with the vent clear |
| C-20 (C-21, C-22) | Sensor malfunction | Turn the oven off and restart it, then cycle the power | If the code returns after a power cycle |
| S-01 | Safety shutoff after running too long | Turn the oven off, remove the food and start again | If it appears without long cooking times |
Samsung range C-24 error
C-24 means the temperature sensor saw the oven heat up faster than it should. The usual cause is a blocked or partly blocked vent at the back of the cooktop, so move any pan or item that is covering it. Turning the oven off and leaving the door open for a minute lets it cool down. If the code keeps returning with the vent clear, book a technician.
Samsung range C-20 (C-21, C-22) error
C-20, C-21 and C-22 are sensor malfunction codes. Turn the oven off and start it again, and if the code remains, switch the power off at the breaker for at least 30 seconds before restoring it. If it comes back after that, a sensor or its wiring needs to be tested by a technician.
Model note: These codes come only from Samsung's UK oven guide. North American models may differ.
Samsung range S-01 error
S-01 is a safety shutoff. The oven switches itself off when it has held one temperature for a very long time. It is not a system failure, so turn the oven off, take the food out and start again as normal. If it appears when you have not been cooking for hours, book a technician.
Model note: The time limits come from Samsung's UK oven guide, and North American models may use different limits.
Control board, button and power codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| C-F0 | Communication error between range electronics | Reset the power, using the breaker if needed | If it returns after a power reset |
| C-d0 | A button is stuck or pressed too long | Clean the buttons with a damp cloth and keep them dry | If it returns with clean, dry buttons |
| C-d1 | Door lock malfunction | Turn the oven off and restart, then cycle the power | If it returns after a power cycle |
| bAd LinE | Power connection is not made correctly | Nothing to try yourself: book a technician | As soon as you see it |
Samsung range C-F0 error
C-F0 means components in the range's electronics have lost communication with each other. Turn the range off and on with the Power button first. If the code returns, switch the circuit breaker off, wait 30 seconds and switch it back on. If it still returns, book a technician.
Model note: Samsung says induction models NSI6D*9100, NSI6D*9300 and NSI6D*9500 can fix this with a software update delivered through SmartThings. Samsung's UK guide describes C-F0 as no communication between the main and sub control boards.
Samsung range C-d0 error
C-d0 appears when a button on the control panel has been pressed and held for a long time. Wipe the buttons with a damp cloth, make sure there is no water on or around them, then turn the oven off and try again. If the code keeps returning, the touch panel may need replacing.
Model note: This code comes only from Samsung's UK oven guide. North American models may differ.
Samsung range C-d1 error
C-d1 points to a problem with the door lock mechanism. Turn the oven off and restart it, and if the code stays, switch the power off at the breaker for at least 30 seconds and then restore it. If the code comes back, the lock needs to be inspected by a technician.
Model note: This code comes only from Samsung's UK oven guide. North American models may differ.
Samsung range bAd LinE error
bAd LinE means the range is not detecting a correct power connection. Samsung says the connection must be made properly according to the installation manual or by a professional installer. Do not pull the range out or work on the connection yourself. Book a technician so the supply connection can be checked safely.
How to reset your Samsung range
For codes that Samsung does not list individually, the documented reset is a simple power cycle. Turn the range off and on with its Power button first. If the code returns, use the circuit breaker, leave it off for 30 seconds, then switch it back on.
- Press the Power button to turn the range off, then press it again to turn it back on.
- If the code returns, switch the range's circuit breaker off.
- Wait 30 seconds, then switch the breaker back on.
- If the code returns again, book a technician.
