I I have several Inkbird units which have failed like this. I’ve tried all the measures advised by Inkbird without success, It is costing me a great deal of money which I can no longer afford. Regards Ron Finlay ---

The ITC-306A controller comes with a 2-year warranty. If it is still under warranty, please provide a video of the problem and order information to [support@inkbird.com](mailto:support@inkbird.com) for after-sales service. ---

Hi Tania, As requested I sent you a video of the fault. I received a reply stating that you want another video! I have several faulty units. In total I have purchased about 15 units, some directly, some via eBay. I don’t have the time to be sending video after video. From what I can gather, the wifi connection issue is very common, and should be appropriately addressed by Inkbird! ---

Please understand that [support@inkbird.com](mailto:support@inkbird.com) is the team responsible for after-sales service. If there is an issue with the product, they will handle it. I suspect that because it involves a large number of platforms and products, and different platforms have different after-sales rules, they might be seeking further confirmation to complete the after-sales application process.
