Smoker does not heat at all; display powers on and appears normal but cabinet stays cold.

Safety first: Unplug the smoker and allow it to cool. Heating circuits can retain heat for some time.

Diagnostic steps:

• Visual inspection of element: Remove the racks and drip tray. Inspect the heating element at the back or bottom of the cabinet for cracks, breaks, or heavy scaling. A visible break usually means the element is bad.
• Check wiring: Access the rear panel and verify that the element’s spade connectors are firmly attached and not burnt. Tighten or replace connectors as needed.
• Test element resistance: Disconnect at least one wire from the element and measure resistance with a multimeter. An open circuit (infinite resistance) indicates a failed element that must be replaced.
• Check high‑limit / thermal fuse: Locate the high‑limit thermostat or thermal fuse in series with the element and test for continuity. Replace if open.
• Control board output: If the element and safety devices test good, the control board may not be sending power to the element. In that case, replace the digital control box.

Always replace damaged wiring with high‑temperature rated wire of the same gauge.
