Turning on your ThermoWorks BlueTherm One thermometer and having it display "ERR" like an error code can be unnerving. However, do not fret! This typically occurs after battery replacement and/or after the stainless steel probe has been removed for thorough cleaning.

The "ERR" is primarily displayed when the stainless steel is not inserted. However, if your probe is properly inserted and the BlueTherm One display is still showing "ERR", your stainless steel probe will more than likely need to be replaced.
