Quick answer
Electrolux microwave code E-12 indicates gas sensor circuit is shorted.
Model compatibility: Electrolux reuses codes across series and control generations, so E-12 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Code E-12 on an Electrolux microwave is associated with gas sensor circuit is shorted. Rule out simple external conditions first, then stop if the code comes back. Use the observed symptoms and the full model number to confirm the correct diagnostic path.
The practical value of this code is that it narrows the next check: gas sensor circuit is shorted. The same display can accompany sensor cooking may not work, so the next step is to rule out gas/humidity sensor problem before moving deeper into sensor wiring issue.
This code set is documented for Electrolux over-the-range microwave models E30MH65GPSA and E30MH65GSSA. Do not apply these meanings to another microwave platform without model confirmation.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Disconnect the microwave from power for several minutes.
Make sure the interior is clean and dry.
Use a manual timed-cook mode only if the appliance otherwise operates normally and no safety symptom is present.
Do not remove the cabinet to inspect the sensor.
Important safety warning. Stop if the code returns or the microwave behaves abnormally.

When to call a technician
The E-12 gas-sensor circuit is internal and should be diagnosed by a trained microwave technician.
A recurring E-12 is more useful to a technician when you also report whether sensor cooking may not work. The next diagnostic path can then verify gas/humidity sensor problem against the control-platform documentation.
Seeing this code on your Electrolux appliance?
If the code returns after the safe checks, book a repair visit and share the exact display plus your full model number.

It indicates gas sensor circuit is shorted. Confirm the full model number because Electrolux diagnostic meanings can vary between control platforms.
You can try the safe external checks on this page and one power reset when appropriate. If the code returns, repeated resets are not a substitute for diagnosis.
Avoid sensor modes if the code returns. Stop all use if there is overheating, electrical odor, or abnormal operation.
