Samsung microwave C-F0: Internal communication warning
THE SHORT ANSWER
Internal communication warning.
C-F0/C-F1/C-F2 belongs to Samsung’s microwave communication group. The complete code helps distinguish control-to-control and touch-interface conditions.
Record the exact suffix before resetting; do not shorten the display to CF.
C-F0C-F1C-F2E-81E-82E-83TEDo not remove the cabinet or bypass door interlocks. Internal microwave components can remain hazardous after power is disconnected.

THE DETAILS MATTER
Scope & troubleshooting notes
How to interpret this result
Samsung’s more detailed tables associate C-F0 with controller communication and C-F2/TE with the touch interface on applicable models. None of these labels alone identifies the part to buy.
Distinct displays covered in this guide
C-F1: A control communication condition is reported; C-F2: A control communication condition, with touch-interface meanings on some models; E-81: The communication path is reported open; E-82: The communication path is reported shorted; E-83: An internal communication fault is reported; TE: The touch interface has a communication fault. These are distinct diagnostic labels grouped by the owner-level response, not interchangeable spellings.
