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°

Hello,
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 support@inkbird.com with your order details and the link of this post.
