Reading C-F0 on the display
Samsung lists CF0, shown with a dash as C-F0, under a communication error for its microwaves. C-F1 and C-F2 read the same way in the list. Samsung files it among the current-generation microwaves.
Before asking for service
Step
Action
1
Take electricity away from the microwave, either by unplugging it or by shutting its breaker.
2
Let the microwave dry if it met a spill or steam from the cooktop.
3
Otherwise, give it 60 seconds and turn the power on again.
4
If the display shows CF0 once more, ask for service.
Service for a Samsung microwave around the Bay Area
A code that survives the reset is a reason to book a visit in San Francisco or across the Bay Area. Open Samsung microwave repair or dial (415) 969-6153, and have C-F0, the model number and the steps you tried at hand.
Model compatibility: Samsung reuses codes across series and model years, so C-F0 / CF0 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
