Error codeC-72 / C72
ApplianceMicrowave
A steam sensor error is what C-72 means when it appears on a Samsung microwave; the dash-free spelling is C72. C-71 and C-70 read the same way in the list.
Samsung files it among the current-generation microwaves.
Steps to try when C-72 shows
Power: Disconnect the supply, whether that means the plug or the breaker.
Moisture: If water or cooktop steam got in, hold off until everything is dry.
Wait: Dry unit? Pause for 60 seconds, then reconnect it.
Still there?: When C-72 returns after the restart, request service.
Need a hand with a Samsung microwave in San Francisco? Phone (415) 969-6153 or go to Samsung microwave repair. Bay Area callers should have the displayed code, the model number and their earlier attempts ready.
Model compatibility: Samsung reuses codes across series and model years, so C-72 / C72 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
