Display shows E1 and the smoker does not heat; heating element never turns on.

Safety first: Unplug the Klarstein electric smoker and allow it to cool completely before opening any panels.

Step-by-step checks:

• Inspect the heating element: Remove the rear or bottom access panel (depending on model). Locate the stainless or black tubular heating element at the bottom of the cooking chamber. Check for visible breaks, burn marks, or deformation.
• Check wiring connections: Verify that the spade connectors on both ends of the element are firmly attached and not corroded or burned. Reseat any loose connectors.
• Test continuity: With a multimeter set to ohms, disconnect at least one wire from the element and measure resistance across the terminals. A good element typically reads between 10–40 Ω. If it reads OL (open), the element is defective.
• Check the thermal fuse / high‑limit thermostat: Many Klarstein smokers have a thermal cutoff mounted near the element or on the back wall. Test it for continuity; if open, it must be replaced and the cause of overheating investigated (blocked vents, grease buildup).
• Control board relay: If the element and thermal fuse test good but E1 persists, the heating relay on the main control board may be faulty. Inspect the board for burned spots or cracked solder joints. Replacement of the board is usually required.

When to stop: If you are not comfortable testing live circuits or replacing the control board, contact a qualified appliance technician.
