Error codeE-51 / E51
ApplianceMicrowave
Quick answer
E-51 is Samsung's microwave code for sense failure. Reset the power; request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so E-51 / E51 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
E-51 means sense failure.
Samsung’s microwave list gives E-51 the label Sense failure, and the unit shows it when that fault is detected. Samsung files it with the codes for current microwave models.
Power reset first
Cut power first by unplugging the microwave or flipping its circuit breaker off. Give a damp unit time to dry, and otherwise count out 60 seconds. Bring power back and look to see whether the code is gone. Repeat appearances of the code mean it is time to request service. Anything beyond the reset belongs to a technician, not to the owner.
