I think the sensor on my 6 month old ITC-308-WIFI is broken. It’s reading about 20 degrees too warm. Is there any way to reset it?

I got a high temperature alarm yesterday. It is set for 75, the temperature reading was 81. I silenced the alarm and unplugged the heater. With no heat source it still raised the temperature to 85 degrees. I tested with a different thermometer and got 68.

Hello,  
Please check that the probe is intact.  
Please ensure that the temperature environment where the probe is within the detection range of the probe. It has not been in contact with corrosive objects/liquids.  
Please clean the probe and cable, and then blow it dry with a hair dryer, does it work?  
If the issue persists, please provide your order information and a description of the problem to email: [support@inkbird.com](mailto:support@inkbird.com) for after-sales service.  
Thanks.
