Quick answer
C-A1 (CA1) is a functional error on a Samsung microwave. Unplug, let it dry or wait, then request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so C-A1 / CA1 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-A1 is a functional error on a Samsung microwave.
If your Samsung microwave is showing C-A1, the display is reporting a functional error. The entry is for current-generation Samsung microwaves.

Samsung’s list gives one description, a functional error, for C-A0 and C-A2 together.
Reset and check
Cut the power first: pull the plug or turn the breaker off.
After contact with a spill or cooktop steam, leave the microwave alone until it has dried.
Otherwise count out 60 seconds and restore power.
A code that returns means it is time to ask for service.
