Polaris Start Button / Keypad Failure

Display and buttons work, but the Start button does not respond; programs cannot be initiated.

Safety Warning

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

Worn Start button contact on membrane keypad, Cracked solder joints on control PCB, Contamination under mechanical button, Damaged ribbon cable to keypad

How to Fix / Troubleshooting

Safety first: Unplug the cooker before opening the control panel.

Test other buttons: If only the Start button fails, the issue is likely local to that key.
Inspect ribbon cable: Reseat the cable between keypad and main board.
Check for cracks: Examine the control PCB for cracks near the Start button area. Resolder or replace the board if necessary.
Replace keypad: If the membrane is worn, install a new Polaris keypad/control panel assembly.
