Smoker shuts off unexpectedly before the timer reaches zero, without showing an error code.

Safety first: Allow the smoker to cool before opening panels.

• Check cord and outlet: Ensure the plug is fully inserted and the cord is not being pulled or flexed during operation.
• Ventilation: Confirm that the smoker has adequate clearance around it and that vents are not blocked, to prevent control board overheating.
• Inspect high-limit thermostat: If it opens intermittently at normal temperatures, replace it.
• Board replacement: If power loss occurs without environmental cause and all connections are secure, the main control PCB may be failing and should be replaced.
