Error codeC-F0
ApplianceMicrowave
Quick answer
C-F0 on a Samsung microwave is a communication error. Try the manual's power reset and request service if it returns.
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
Communication error.
A Samsung microwave that shows C-F0 is reporting a communication error. The display may also read CF0.
It is listed for Samsung microwaves in the current series.
What to do first
Unplug the microwave, or switch off its circuit breaker.
If it is wet, give it time to dry. If it is not wet, wait 60 seconds.
Restore power and turn the microwave back on.
If C-F0 comes back after that, the next step is to request service.
If the code stays after the reset, call (310) 896-4231 for Samsung microwave service in Los Angeles, and see microwave repair for the service. Have the code, the model number and the reset you tried ready.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
