Display shows F2 and the smoker stops mid‑cycle; fan and heater shut off.

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

Steps:

• Check latch tension: Close the door and tug gently; it should not move easily. Tighten latch screws or adjust the strike plate to increase tension.
• Inspect magnet alignment: Ensure the door magnet lines up directly with the reed switch when closed. Adjust the magnet position if necessary.
• Test for vibration issues: Run the smoker while gently tapping the door. If F2 appears, the switch is likely intermittent. Replace the door switch.
• Control board input: If a new switch does not resolve the issue, the door input circuit on the control board may be faulty and require board replacement.
