Hi I'm Brian and I'll be happy to help with this!

Generally the cause of this is the battery terminals in the thermostat have some corrosion on them. You can try using an emery board (finger nail fail) or pencil eraser to carefully and gently clean up the batter terminals on the thermostat itself and sometimes you can fix it this way. If that doesn't work, then yes, chances are your thermostat is beyond repair and should be replaced.

Let me know if you have further questions about this.

Thanks,

Brian
