The LL on the freezer thermometer indicates that the internal temperature of the freezer is so low that the thermometer cannot read it. Try raising the freezer temperature by one degree.
Question (applies to all models): My thermometer is displaying an LLL or HHH error. What does it mean?
There are several reasons your thermometer may display either an LLL or HHH error, the most common being that the probe was damaged or broken.
If your thermometer may have been exposed to temperatures above or below its temperature range (see below for your model), you will see one of these errors. The errors may also indicate that there are other types of damage to the probe.
Sometimes, doing a hard reset will resolve the problem. Remove the battery. Leave the battery out for at least one minute before installing a new battery.

How do you fix a probe thermometer?
Sometimes this can be corrected by baking the probe in a 250 ° F (120 ° C) oven for 10-15 minutes as this will evaporate any moisture trapped in the probe. Make sure to connect only the probe + cable to the oven, not the plug or the transmitter.
