My digital thermometer not showing LO singnal

The sensor is sensing a temperature that is lower than the lowest possible temperature that can be displayed on the thermometer. If it is actually warm then the sensor has failed

Yes

This might be due to calibration or the thermocouple is bad. You can get new thermocouples here http://www.taylorusa.com/restaurant-hospitality/thermometers?t_type=42

They also have contact info and calibration procedures.

Have you tried replacing the disposable-lens filter ?
The manual is available at: http://brauntherms.com/downloads/IRT4020_4520_MNLA_U.0035_OM_25JAN11.pdf

I just had that LO reading. Pulled back on the tip of the thermometer. Seems I had it inserted into my turkey too far. Probably up against a bone or too close to the center. Good luck! Happy Thanksgiving 2016!

the LO is just saying low tempeture it will go away in a min or 2 then should be able to use or try to replace the batteries

there should be a setting on it that changes the temp from Celsius or "c" to ferinheight and lo means that it currently isn't reading a temperature in the normal range. try running it under hot water and see if it says error or high.

you have to change the battery of your thermometer, its already weak,you need to replaced it.

The temperature of the thermometer is lower than 60°F
(15.5°C). Let instrument acclimatize for about 30 minutes
in a warmer area in which it will be used.

To put it simple, the thermometer unit is to cold to use. Try leaving it in a warmer room for 30 minutes. Then try using it again.

Here is a link to the manual if you should need it:
