Error codeC-F0
ApplianceRange
Quick answer
C-F0 means no communication between main PCB and sub PCB. Reset power; some induction models can update via SmartThings.
Model compatibility: Samsung reuses codes across series and model years, so C-F0 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
C-F0 is a communication error between electronic components, with no communication between main PCB and sub PCB.
C-F0 indicates a communication error between components in the electronics of the range. In Samsung’s table it means there is no communication between the main PCB and the sub PCB.
Induction models with a software update
On induction range models NSI6D*9100, NSI6D*9300 and NSI6D*9500, a software update resolves the error without service. Reset power to the unit first, which makes the code disappear for a while. Then connect the range to SmartThings.
If the range was never connected, open the settings menu on the range, press and hold the Light for more than 3 seconds, and go to Restart. Restarting after the connection prompts an update within the next 30 minutes. During the update the display reads Upgrading, with up to 30 minutes required, then Completed, and the range restarts itself. The SmartThings app shows the firmware version, which should be DE92-04769A_24052400 or later.
Other models
Turn the oven off and restart it. If the code continues, cut the power for 30 seconds or more and reconnect. If the update is not possible, or the error remains after it, request service.
