Modern thermostats have a digital screen that lets you view the current temperature and the temperature outside, along with the settings. A blank or black screen is a problem because it keeps you from adjusting or even using the unit. We’ll go over some of the reasons you may have a blank thermostat screen in Alamogordo, NM below.
No Power
Most thermostats use a couple of batteries, either for power (if the unit isn’t hardwired) or as backup in case of power outages. If the screen keeps blinking in and out, changing from bright to dark, the chances are good that the batteries are going out. If the screen turns black and doesn’t respond, the batteries might be dead.
Lose Wires
If someone hardwired your thermostat so it draws power from your HVAC system, the issue could be with the wiring. When one of the wires that connects it to the system is loose, it can prevent the thermostat from getting the necessary power. The screen can appear blank if the backup batteries are dead and the wire loosens.
Other Power Issues
There are various different power issues that can affect whether your thermostat receives power. One issue is a blown fuse, which prevents power from reaching the thermostat and anything else that uses the same fuse. If you live in a home with a circuit breaker, a tripped breaker will make the screen go blank.
Dead Thermostat
If none of these problems are the culprit, you might have a dead thermostat on your hands. Replacing it give you a chance to install a more energy-efficient smart thermostat.
