Quick answer
E-04 on a Samsung microwave is a cooking time setting over error (convection). Try the manual's power reset and request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so E-04 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
