What E-31 means

Here is a code that repeats a name you may have seen for E-11. E-31 is listed on Samsung US microwaves as an open gas sensor error, meaning the control found a broken path in the circuit of the vapor sensor used in sensor cooking. Because the same wording sits under two numbers, we confirm by model which sensor input each one covers. The visible result is a code and sensor programs that will not run.

Common causes of E-31

The sensor circuit reading as open to the control
A loose connector or wire between the sensor and the control
Condensation that settled near the sensor

✓ One safe check you can try

1. Pull the plug, or flip the breaker. 2. Give moisture time to dry with the door open. 3. Wait 60 seconds, and then power the oven on. 4. Run a short timed cook instead of a sensor program and see whether it heats. 5. If the E-31 display reappears, request service.

! Why to stop there

The wording matches E-11, so the model decides which sensor input the code points to, and we check that first.
An open reading can come from the sensor, a wire or the control input, and we test them in that order.
We give you the price in writing before we begin.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E-31E-31 questions

Is E-31 the same problem as E-11?

The wording is the same, an open gas sensor, but the numbers differ. We treat them as separate and confirm by your model which sensor input the code belongs to.

Does the oven still heat?

Timed cooking commonly still works, because it does not rely on the vapor sensor. Test with a cup of water for a minute and only use that mode if it behaves normally.

Can cooking steam cause it?

A lot of steam around the sensor can upset the reading, which is why drying the oven out comes first. If E-31 reappears on a dry oven, we look at the circuit.
