ApplianceMicrowave
Quick answer
C-A2 (CA2) 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-A2 / CA2 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-A2 is a functional error on a Samsung microwave.
Your Samsung microwave has put CA2 on the display: that is a functional error. Current-generation Samsung microwaves use this code.
Reading the C-A2 code
The same table line covers C-A0 and C-A1; each is read as a functional error.
First steps
Take the power away: unplug the unit or flip its circuit breaker off.
Had a spill, or steam from a cooktop, reached the controls lately? Allow time for everything to dry.
Otherwise count out 60 seconds and restore power.
Should C-A2 come back, the manual says to request service.
For a Samsung microwave in Los Angeles, call (310) 896-4231 and describe what the display shows. Keep the model number handy, note that the display says C-A2, and mention the restart you did. More on microwave repair.
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.
