Error codeC-F2 / CF2
ApplianceMicrowave
A Samsung microwave that flashes C-F2 (or CF2) is reporting a communication error. C-F1 and C-F0 are listed together with it under one label. You will find it in the table for newer, current-generation microwaves.
A short reset routine
Begin by disconnecting the microwave: pull the plug or turn the breaker off.
Any wetness, whether a spill or cooktop steam, has to dry before you go further.
With no moisture involved, count out a minute (60 seconds) before switching power back on.
Should C-F2 reappear, the next step is to request service.

Back-to-back C-F2 after a restart? San Francisco and Bay Area owners can contact us on (415) 969-6153, and Samsung microwave repair explains the service. Gather the model number, the code and a note on your reset first.
Model compatibility: Samsung reuses codes across series and model years, so C-F2 / CF2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
