Whirlpool undercounter ice maker not making any ice at all (no error code displayed)

Safety: Always unplug the ice maker or switch off the breaker before removing panels.

• Verify power: Check that the outlet has 120 VAC using a multimeter or by plugging in another appliance. Reset any tripped breaker or GFCI.
• Check power cord and plug: Inspect for damage or burn marks. Replace the cord if compromised.
• Inspect on/off switch: Ensure the switch is in the ON position. Test continuity through the switch; replace if it does not close when turned on.
• Door switch (if equipped): Confirm the door switch is being fully depressed when the door closes. Test continuity and replace if faulty.
• Control board: If power is present at the board but no components run and indicator lights are off, the main control board may be defective and require replacement.
