3 Causes for a Blank Thermostat Screen in Seneca, SC

Considering all of the important information displayed on the screen of a programmable thermostat, having it turn completely blank may make you uneasy and confused. There’s no need to worry, however. Here are some reasons why a thermostat screen might go blank and what homeowners in Seneca, SC can do to bring things back to normal.

1. Dead Batteries

The first thing you should do if your thermostat’s screen has turned blank is check the batteries. The batteries may be dead, or they may have started leaking. In the former case, you need to replace the batteries with new ones.

If the batteries have leaked into your thermostat, you’ll have a much more serious problem. We recommend asking a professional to remove the corrosion that that leak has caused. If that’s not possible, you’ll probably need to replace the entire device.

2. A Broken Thermostat

The next set of possible explanations all concern the many things that might be wrong with the thermostat itself. One such possibility is that your thermostat is simply too old and can no longer function. As a rule, you should think about replacing your thermostat after 10 years.

Additionally, the device may have loose, frayed or otherwise damaged wires, or it may have a malfunctioning circuit board. Issues like these call for maintenance or repair services from HVAC technicians.

3. Electrical Issues

Lastly, there might be broader issues with your home’s electrical system. Your HVAC system may have tripped your circuit breaker, for example, and if your thermostat and HVAC system receive power from the same source, this will cut off power to the thermostat. Another possibility is that something is wrong with the electrical wiring in your home.
