Ninja Keypad / Touch Interface Failure

Buttons on the control panel are unresponsive or respond intermittently.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Moisture under keypad, Worn membrane switches, Damaged ribbon cable, Faulty touch controller IC

Safety first: Unplug the unit before cleaning the control panel.

Clean surface: Wipe the control panel with a slightly damp cloth and then dry thoroughly. Do not spray cleaner directly onto the panel.
Dry out moisture: If the panel was exposed to spills, leave the unit unplugged for 24 hours.
Test pattern: Note which buttons fail; if an entire row or column is dead, the ribbon cable or controller is likely at fault.
Replace panel: Persistent unresponsiveness usually requires replacement of the control panel assembly.
