Interior light does not turn on, but smoker otherwise works normally.

Safety first: Unplug the smoker and allow the interior to cool.

• Check bulb/module: Access the interior light cover and inspect the bulb or LED module. Replace if visibly burned or darkened.
• Inspect wiring: From the access panel, verify that the light wiring is intact and connected to the control board.
• Test switch: If there is a dedicated light button, ensure it clicks and is not stuck. If the light never comes on, the control output may have failed.
• Replace component: Install a new Cuisinart light module or, if no power is reaching it, replace or repair the control board light circuit.
