LG Microwave Error Code E10 — Internal Short Detected
What this means
The E10 error code indicates the microwave's control board has detected an internal short circuit. This can be caused by a power surge, moisture damage, or a component failure on the control board. The microwave may not respond to any button presses until the short is resolved.
Step-by-step fix
2 stepsUnplug and reset
Unplug the microwave for 1 minute, then plug it back in and test the control panel.
Check for moisture
If the microwave was exposed to steam or moisture (common for over-the-range models), wipe the control panel area dry and allow it to air out before retrying.
When to call a professional
If the error persists, the control board has likely sustained permanent damage and needs professional replacement. Note: microwave repair involves high-voltage capacitors that can be lethal even when unplugged. Do not attempt to open the cabinet.
