My actual sensor looks like this:

 

The left hand sensor is wired, the right one isn't Whilst it's a little snug when closing (as the door has expanded slightly), the sensor cases are not at all loose.

Any ideas? Thank you so much!

No picture but your comment suggests even more so, lid tamper is likely cause.

Sorry! Hopefully this will show the picture....

 

 

Is this something that you think I could fix?

Ah, Elmdene contacts. Yuck. I hate their surface models.

 

If the lids are tight, you'll really have to call someone out who would probably change the contact.

 

We do have members in that area, there is a directory on here or you could use the SSAIB and NSI searches as above.

 

Hope this helps!

That also needs realigning.

Yes , they don't work that good fitted that way, and don't have lid tamper must be connection problem, are they all the same comes with a tail and join is act somewhere else?
