What E12 Means
E12 is documented by Whirlpool as a problem with the gas sensor or the associated wiring - the companion code to E11 in the sensor-cooking system.
Common Causes of E12
- Gas sensor failure
- Wiring or connector fault
- Control board fault
🔧 One Safe Check You Can Try
Cut power at the breaker or unplug for five minutes and restore. Use manual cooking modes meanwhile. If the code returns, arrange service; the sensor sits inside the cabinet of a heavy overhead appliance. A microwave capacitor can hold a lethal charge long after the oven is unplugged - this is the one appliance where "unplug it and have a look" is genuinely dangerous advice.
⚠ Why You Shouldn't Go Further Than That

- Overhead mounting makes this an awkward and heavy appliance to open.
