Display shows E10; smoker powers on but immediately beeps and will not start.

Safety first: Unplug the smoker before adjusting the door or switch.

• Inspect door closure: Close the door slowly and verify it aligns evenly with the cabinet. Look for gaps or twisted hinges.
• Check latch and strike: Examine the door latch and the cabinet strike plate or magnet. Tighten any loose screws and ensure the latch fully engages when the door is closed.
• Locate door switch: Find the door switch (mechanical plunger or magnetic reed) near the door frame. Press it manually (for plunger types) and listen for a click.
• Test continuity: With the smoker unplugged, disconnect the switch and test continuity while pressing and releasing it. Replace the switch if it does not open and close reliably.
• Adjust door alignment: If the door is sagging, slightly loosen the hinge screws, lift the door into proper alignment, and retighten.
