Controller buttons unresponsive or require very hard presses.

Safety first: Unplug the smoker before removing the controller.

Steps:

• 1. Clean surface: Wipe the keypad surface with a slightly damp cloth and mild detergent. Do not soak or allow liquid to run behind the overlay.
• 2. Check for physical damage: Look for cracks, bubbles, or peeling of the keypad overlay. If damaged, the controller or overlay should be replaced.
• 3. Test all buttons: After cleaning, plug in and test each button. If some remain unresponsive, the keypad contacts are likely worn.
• 4. Replace controller: Most Cookshack IQ controllers are replaced as a complete assembly when the keypad fails.
