Smoker shuts off mid-cook; display goes dark and then may come back on after cooling.

Safety first: Allow the smoker to cool and unplug it before inspection.

Steps to diagnose mid-cook shutdown:

• Check power cord and plug: Ensure the plug fits tightly in the outlet and is not hot to the touch after use. Replace if discolored or loose.
• Avoid extension cords: If you must use one, ensure it is heavy-gauge and short. Undersized cords can overheat and drop voltage.
• Inspect internal connections: Open the rear panel and check the terminal block and control board power connections for looseness or heat damage. Tighten and replace as needed.
• Check for blocked ventilation: Ensure the control housing vents are not blocked by grease or debris, which can overheat the board and cause shutdown.
• Test again: After corrections, run the smoker empty for an hour at a moderate temperature to confirm stable operation.
