Quick answer
C-71 (C71) is an error with the steam sensor on a Samsung microwave. Unplug, let it dry or wait, then request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so C-71 / C71 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
C-71 is an error with the steam sensor on a Samsung microwave.
Your Samsung microwave has put C71 on the display: that is an error with the steam sensor. The entry is for current-generation Samsung microwaves.
What C-71 means
C-70 and C-72 are listed together with it under a single heading: an error with the steam sensor.
First steps
Turn the microwave off at the breaker or unplug it from the wall.
Moisture is the first thing to rule out: after a spill or cooktop steam, let the microwave dry out.
If nothing got wet, give it 60 seconds and power it up again.
