LG Oven Error Code CFA — Over Current Detected
What this means
Error CFA indicates the control board has detected an over-current condition, meaning more electrical current is flowing through the circuits than expected. This can be caused by a shorted heating element, a wiring short, or a control board issue. This is a safety shutdown to prevent electrical damage or fire.
Step-by-step fix
4 stepsTurn off the breaker
Disconnect power immediately to prevent further electrical issues.
Check heating elements
Test the bake and broil elements for continuity and resistance. A shorted element can cause over-current.
Also test each element to ground — no continuity should exist between the element terminals and the oven frame.
Inspect wiring
Look for burned, melted, or shorted wiring inside the oven.
Professional diagnosis
If elements and visible wiring check out, the control board may have an internal failure requiring professional diagnosis.
When to call a professional
Over-current conditions involve electrical safety. Professional diagnosis is strongly recommended.
