What to do if my Kamado Joe PELLET JOE Grill overheats and shows Err 3?
- YymarksAug 20, 2025
If your Kamado Joe Grill displays 'Err 3', it means the grill has overheated, and the pit probe reached a temperature greater than 800F. The fan will run at 50%, and the auger will remain off until the set temperature is reached. Turn off your grill by turning the control dial to the OFF position. Check for potential causes of overheat, such as a grease fire or too many pellets in the crucible, and then restart the grill.
