Display shows E8 and smoker shuts off when reaching higher temperatures.

Safety first: Unplug the smoker and allow it to cool completely.

• Check ventilation: Ensure the smoker is not placed against walls or under low overhangs. Maintain clear space around vents and the rear panel so heat can escape.
• Inspect high‑limit thermostat: Access the rear or bottom panel and locate the high‑limit thermostat (small round or rectangular device in series with the element wiring). Check for loose connectors or burned terminals.
• Reset (if manual reset type): Some high‑limit thermostats have a small reset button in the center. Once the smoker is cool, press firmly to reset.
• Test continuity: With power disconnected, remove one wire from the thermostat and test for continuity across its terminals. If it is open at room temperature and does not reset, it must be replaced.
• Replace thermostat: Install a Cuisinart‑compatible high‑limit thermostat with the same temperature rating and reconnect wires securely.
