When your smart thermostat screen is blank, you can’t control the temperature of your home in Severna Park, MD. Quick diagnostic and repair services are necessary to maintain a comfortable indoor environment. These are a few common causes of a blank smart thermostat screen:
Dead Batteries
One of the most common causes of a blank smart thermostat screen is dying or dead batteries. As the batteries lose power, the display typically appears intermittently before it stops functioning completely. To avoid this problem, replace the thermostat’s batteries as part of your annual system maintenance.
Tripped Breaker
A tripped breaker can cause your smart thermostat screen to go blank. If the system pulls too much power, or there are other electrical issues, the circuit breaker may resolve the problem. Otherwise, consider scheduling a professional diagnosis and repair service.
Faulty Wiring
Faulty wiring connecting the thermostat to the HVAC system prevents these components from communicating with each other. Faulty wiring is most common after the installation of a new thermostat. Prevent electrical damage and injuries by hiring a professional to do the work.
Wiring issues can also stem from the thermostat suffering some sort of damage after being installed correctly. For instance, a rodent problem inside your walls can lead to wiring issues that often result in a blank thermostat screen.
Tripped High-Limit Switch
A thermostat has a high-limit switch that is responsible for preventing overheating. Damaged parts or poor airflow are common causes of overheating. If your high-limit switch trips due to overheating, the thermostat screen turns off a few minutes after the HVAC system switches on.
If your thermostat screen is blank, we can diagnose the problem and replace the device with a new model if needed. Schedule repair service with Coastal Heating & Air Conditioning Co., Inc. today.
