Freezer shows E6 and may not cool; fans may run but compressor stays off.

Safety: Disconnect power before touching any control boards or wiring.

Basic reset:

• Unplug the freezer for at least 10–15 minutes to fully discharge the control board.
• Plug back in and observe if E6 reappears immediately or after a short delay.

Inspect wiring and connections:

• Access the main control board (often behind the rear panel or in a top control housing).
• Check all harness connectors for full insertion and locking tabs engaged.
• Look for burnt components, bulging capacitors, or scorch marks on the PCB.

Check supply voltage:

• With the unit plugged in (use extreme caution), verify that the board is receiving proper line voltage at its input terminals.
• If no power is present, check the power cord, outlet, and any inline fuses.

Replace the control board if defective:

• If E6 persists and no wiring issues are found, replace the main control board with an Igloo-compatible board for your exact model.
• Transfer any jumper settings or wiring positions exactly as on the original board. Take photos before removal to ensure correct reconnection.

Final test: Restore power and confirm that the display operates normally, the compressor cycles on, and the E6 code does not return.

Note: If you are not comfortable working around live voltage, have a professional technician perform these checks.
