Display is on and buttons respond, but the ice maker will not start a cycle when Start is pressed.

Safety: Unplug the unit before inspecting sensors.

Steps:

• Empty the bin: Remove all ice and ensure nothing is blocking the bin full sensor or mechanical arm.
• Check water level: Fill the reservoir to the indicated max line with clean water. Some models will not start if the level is too low.
• Door/lid switch: If your Northair model has a lid switch, ensure the lid closes fully and the switch actuator is not broken.
• Reset control: Unplug the unit for 5 minutes, then plug back in and attempt to start a cycle.
• Sensor replacement: If the bin full sensor or lid switch tests faulty with a multimeter, replace the defective component.

Note: Refer to the user manual for any child lock or control lock features that may need to be disabled.
