Buttons beep but smoker does not start cooking when Start is pressed.

Safety first: Ensure the door is fully closed before attempting to start.

Steps:

• Open and firmly close the door; listen for the click of the door switch.
• Verify that a valid temperature and time have been set according to the manual.
• Check the door switch for proper operation with a multimeter and replace if it does not close when the door is shut.
• Perform a control reset by unplugging the smoker for 5 minutes, then reprogramming the cook cycle.
