ITC 308 "AH 120°c" flashing

Hi my Inkbird ITC 308 has been sensing higher temperatures and now its flashing 120° on the top screen and reading 30° on the bottom screen ( the temperature is about 15°

PV is the temperature probe reading.
Please clean the probe and cable, then use a hairdryer to dry the probe, then test the probe in the air temperature, can it read correctly?
If no, please email with your order details and the link of this post.
