Why is My Thermostat Blank?

Reasons Your Thermostat is Malfunctioning

A blank thermostat screen is always frustrating and can happen due to a variety of reasons. Fortunately, many times a blank thermostat screen can be easily fixed without having to spend a lot of money. Here are a few of the most common reasons for a blank thermostat screen.

1. An Open Furnace Door

Your thermostat may be blank due to an open furnace door. Some thermostats are more sensitive than others, and it always a good idea to check to see if the door is securely closed.

2. Circuit Breaker Tripped

Another common reason for a blank thermostat screen is a tripped circuit breaker. You need to reset the breaker and check to see if that resolves the issue. If you still experience issues or are not confident you know where your circuit breaker is located, contact our team of professionals.

3. Brightness Settings Too Low

Sometimes the brightness settings on your programmable thermostat are too low, which makes it much more difficult to display the temperature. Many thermostats automatically dim the screen at a particular time each day. You can adjust these settings at any time to find a solution that works best for you.

4. Dead Batteries

Many thermostats require batteries to display the screen. Changing the batteries is a simple solution that can fix a blank thermostat screen. It is also a good idea to change the batteries periodically to avoid corrosion.

5. Electrical Issues

Faulty wiring can cause a wide range of problems with a thermostat. This is especially common if you are having trouble right after installation. Contacting an experienced HVAC company is always a good idea to verify that the installation is correct.

Following these simple solutions are an effective way of fixing a blank thermostat screen.
