Electrolux ice maker shows E12; unit attempts to start but immediately shuts down.

Safety First: Turn off the breaker before inspecting wiring. Only test live voltage if you are trained and equipped.

• Verify dedicated circuit: Ensure the ice maker is on a dedicated circuit of the correct amperage per Electrolux installation instructions.
• Check outlet wiring: Inspect the receptacle for signs of heat damage or loose terminals. Tighten or replace as needed.
• Measure voltage: With a multimeter, confirm the outlet provides the correct voltage (e.g., 120 VAC). Large drops when the unit starts indicate a supply issue.
• Inspect internal connections: Remove the rear panel and check the terminal block, ground connection, and harness to the control board for looseness or discoloration.
• Replace control board: If supply voltage is stable but E12 persists, the internal power supply on the main control board may be defective. Replace the board with an OEM Electrolux part.
