E12 names the gas sensor or its wiring. The manufacturer's reset is a breaker off-and-on with a one-minute watch.
Model compatibility: KitchenAid reuses codes across series and model years, so E12 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
A problem exists with the gas sensor or the wiring that belongs to it.
E12 sits right after E11 in the KitchenAid over-the-range microwave list, and both involve the gas sensor. For E12 the wording is direct: a problem with the gas sensor or the associated wiring.
At a glance
| Code | E12 |
|---|---|
| What it means | A problem exists with the gas sensor or the wiring that belongs to it. |
| What you can check | Cut power at the breaker for a minute, then restore it and keep an eye on the display for another minute. Make sure the microwave still runs. |
| When to call a technician | If E12 stays or returns, schedule a service visit. The sensor and wiring are not for owners to reach, and the cover should stay on because of high-voltage parts. |
KitchenAid’s reset, step by step
| Step | What to do |
|---|---|
| 1 | Turn the breaker(s) off and keep them off for a minute |
| 2 | Turn the breaker(s) on |
| 3 | Keep watching for a minute to see whether E12 shows again |
| 4 | Make sure the microwave runs |
Where it differs from E11
The causes are the same for both codes. E11 uses “possible problem” and E12 drops the word “possible.” The manufacturer does not say either one is more serious, so no ranking is offered here.
If it stays or comes back
KitchenAid’s page ends with a direction to call or schedule service. The sensor and wiring are not meant to be reached by an owner, and a microwave keeps energy in high-voltage parts. Leave the cover on.
