Possible Causes

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing internal electronics.

Basic troubleshooting:

  • Unplug the smoker for 10 minutes to reset the control.
  • Plug into a different outlet on a separate circuit to rule out power noise or interference.

Inspect control board:

  • Remove the control panel and inspect the main control board for burned components or corrosion.
  • Ensure all connectors are firmly seated.

Repair: If F5 recurs frequently and basic resets do not help, replace the main control board. There is typically no field repair for internal timing circuits.
