Door sensor stuck on open. Fine for past 3 years

Front door sensor started throwing the door open code this week after working fine since 2019. Replacing the battery fixed it for 4 days. Now it’s back. What tho try now?

Hi @Scott65. I’d recommend performing a factory reset on your Contact Sensor, then setting it back up in the Ring app using the steps under Set Up a Device. You can find steps on how to factory reset your Ring Alarm components here. If the Contact Sensor is still stuck on open or on Tampered after performing a factory reset and new set up, please follow up with our support team at one of the numbers available here, and request to speak with the Ring Alarm team. If you are outside of the US, please visit here to see how to contact support.
