E9 error; unit may not start or may shut down shortly after starting.

Safety First: Turn off the circuit breaker before inspecting electrical connections. If you are not comfortable working with electricity, contact a qualified technician.

• Verify outlet: Confirm the ice maker is connected to a properly grounded outlet with the correct voltage as specified on the rating plate (typically 115V AC).
• Check breaker: Ensure the dedicated breaker is not weak or tripping intermittently. Reset if necessary.
• Inspect power cord: Examine the power cord for cuts, burns, or crushed sections. Replace if damaged.
• Internal connections: Remove the control compartment cover and check that all wire nuts and plug connectors to the main control board are tight and free of corrosion.
• Board replacement: If supply voltage is correct and connections are solid but E9 persists, the main control board may have a failed power supply circuit and should be replaced.
