If your thermostat is not working, the best thing to do is call a professional. They will be able to help you determine the root of the problem and fix it.

If your thermostat is not working, there are a few things you can do to try to fix it. First, check the batteries to make sure they are still in good condition. If they aren't, replace them. Second, try cleaning the thermostat with a damp cloth. If that doesn't work, try turning it off and on again. If none of those things work, you may need to buy a new thermostat.
