Error codeE-31
ApplianceMicrowave
Both E-31 and E31 lead to a single line in Samsung’s published microwave codes: open gas sensor error. This entry is for the current series of Samsung microwaves.
Similar messages
E-06 covers a swing heater error; E-13 is listed as a T1 max time gas sensor error; C-22 points to a temperature sensor error.
Steps from the manual
Make the microwave dead by unplugging it or flipping its breaker.
Wet unit: let it dry. Dry unit: leave it 60 seconds.
Then switch the power back on and look at the display.
A repeat of E-31 after the reset means it is time to request service.
