Cuisinart Intermittent Power Loss or Thermal Protection Trip

Smoker shuts off unexpectedly in the middle of a cook without any error code.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose power cord connection, Overheating control board, Failing high‑limit thermostat, Faulty on/off switch

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

Check cord and outlet: Ensure the plug fits snugly in the outlet and the cord is not being pulled or flexed.
Inspect switch: If your model has a mechanical power switch, verify it is not loose or arcing; replace if necessary.
Check ventilation: Make sure the control housing has adequate airflow and is not blocked.
Test high‑limit thermostat: If it opens intermittently at normal temperatures, replace it.
