Hi,

I have an **Inkbird Temp Controller ITC-308 WIFI**. It was working well, but the thermostat has suddenly failed…

It’s dramatically over-estimating the temperature. When the actual (confirmed) water temperature is 19C, it reads 30C, sets off the high temperature alarm (‘AH’ / ‘APP’) and starts the cooling fan(!!)

It’s 21 months old.

Please advise what to do. Can this fault be fixed?

(Because Ink Bird only warranties the temperature sensor - the most important part! - for a measly 12 months, I suspect it’s because they know it will fail soon after. They can get people to buy a new one every year or two. Please tell me I’m wrong 😕 )

Target temperature is 23.4C.  
Low temperature alarm set to 20.5C.  
High temperature alarm set to 28.0C.

Thanks for any clever fixes!

Hello,  
Please check that the probe is intact. 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 not, please provide the problem description and order information to email [support@inkbird.com](mailto:support@inkbird.com), maybe they can offer a next step solution.
