Quick answer
E-12 on a Samsung microwave is a short gas sensor error. Try the manual's power reset and request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so E-12 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
