Ring Alarm
Contact sensor tamper
After working flawlessly for several months, one of my contact sensors repeatedly tampers causing home mode alarms . Battery is fine. How do I fix this or check to see if the sensor now faulty?

Hi there, @duggo33! The common reason for an Alarm device to show as tampered is when the cover is loose. Try removing the Contact Sensor cover then putting it back on to see if the tamper clears. Check out [this Community thread](https://community.ring.com/t/device-tampered/50093) for more tamper message troubleshooting tips. I hope this helps! :)

Thanks Marley-- Did that after the alarm woke me in the middle of last night. Tamper actually cleared as soon as I touched the sensor. Then, about an hour later, the alarm again woke me up. Tamper again cleared as soon as I touched it , but this time I simply disabled the home mode. Now wondering if I should simply install a different sensor to see what happens. doug

Thank you for that update, and sorry to hear that this still resulted in an unintended Alarm trigger. Excellent idea to place a different sensor there, as this would really rule out most any other factors. As a mere touch seemed to have cleared the tamper concern, it is likely that another sensor in that area will behave normally when you test. Our [troubleshooting help center article](https://support.ring.com/hc/en-us/articles/360042311972-Troubleshooting-your-Contact-Sensor-2nd-generation-) for the Contact Sensor has some steps for resetting the device. If you have not already, try the reset to see if it resolves this concern. If the Contact Sensor in question continues to show as tampered no matter what you try, this may require a more in-depth look from our support team. Please give our support team a call at one of the numbers available [here](https://support.ring.com/hc/en-us/articles/213608406#callus).

OK, I installed a new contact sensor and it has been fine for the past few nights while on Home mode. Today I did a factory reset of the problem sensor and then reinstalled it on the same kitchen window. It took only 10 minutes for it to show tampered again. The new sensor on the same window remained fine. Again simply tapping the tampered sensor removed the tamper and it is still closed a couple of hours later. That initial tamper however is too much threat for me and I now simply don't trust it, especially for Away mode. So unless you have another suggestion I will uninstall it again before I next change modes. doug

Further information: this is a 2nd generation sensor and the gap is about 1/8 inch. The battery cover is firmly clicked in and in the correct place. The sensor is on an unused window that is never opened.
