ApplianceMicrowave
Quick answer
E-72 is Samsung's microwave code for steam sensor short error. Reset the power; request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so E-72 / E72 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-72 means steam sensor short error.
Your Samsung microwave has stopped on E-72, which Samsung’s microwave list describes as a steam sensor short error. It is one of the codes Samsung lists for current microwave models.
Power reset first
Begin at the plug or the breaker and turn the microwave off at one of them. A wet microwave needs time to dry out, while a dry one only needs 60 seconds of rest. Bring power back and look to see whether the code is gone. If the same code is back once power is restored, Samsung says to request service. Keep the cabinet closed and leave deeper checks to a technician.
