Error codeE-51 (E51)
ApplianceMicrowave
E-51 is the entry Samsung’s microwave table labels a sense failure. It belongs to the list for current-generation models, and some displays drop the hyphen and show E51.
A reset to try
Pull the plug, or switch the circuit breaker off.
A wet microwave has to dry out first; a dry one only needs a 60-second pause.
Restore power and watch the display.
If the code is back
A sense failure that reappears after the reset is Samsung’s cue to request service. The inside of the cabinet is technician territory.
Bay Area owners whose microwave still shows E-51 after the reset can phone (415) 969-6153. Start with Samsung microwave repair, and keep the model number, the code and your reset notes within reach.
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
Samsung's microwave table lists E-51 as a sense failure.
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.
