I´ve made a mistake and over loaded the “Heating” output. (I \> 10 A) Now the Controler keeps showing an “ER” message. Is it possible to repair the Controler? ---

Hello, If ITC-308-WIFI displays ER, it means the probe is faulty. ![image](https://canada1.discourse-cdn.com/flex031/uploads/inkbird1/original/2X/1/1486d12cbba26f86d8f362bd365501366def2892.png) May I know the actual temperature? Please check that the probe is intact. Please ensure that the temperature environment where the probe is placed is within the range of -50~120 °C / -58~248 °F. 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 it does not work, please provide your order information, and a link to this post to **email** [support@inkbird.com](mailto:support@inkbird.com) for after-sales service. Since forum posts are public, these may involve private information, please do not reply here. Thanks. ---
