Error codeE-46 / E46
ApplianceMicrowave
Quick answer
E-46 is Samsung's microwave code for primary open error. Reset the power; request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so E-46 / E46 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-46 means primary open error.
Your Samsung microwave has stopped on E-46, which Samsung’s microwave list describes as a primary open error. The entry belongs to the current Samsung microwave line.
What to do first
Disconnect the microwave from power, either at the plug or at the breaker. If the unit is wet, let it dry; if it is not, wait 60 seconds. Then plug it in or turn the breaker on and test it. Repeat appearances of the code mean it is time to request service. Keep the cabinet closed and leave deeper checks to a technician.
Related codes
If the display actually reads something else, compare it with E-42 (short easy/PH sensor error), E-45 (cooling error), E-47 (door open error) and E-41 (open easy/PH sensor error).
