Why Is My Smart Thermostat Screen Blank in Viera, FL?

A blank smart thermostat screen causes problems, limiting access to the functions needed to adjust it. Functions such as changing the temperature settings, setting a schedule and connecting to Wi-Fi are all affected when the screen is blank. Here are the most common causes of a blank smart thermostat screen in Viera, FL, and how to troubleshoot them:

Dead Batteries

If your smart thermostat is battery powered, dead batteries could be the culprit behind a blank screen. The first step is to replace the batteries and see if that resolves the issue. If it doesn’t, you may need to check other possible causes.

Malfunctioning Circuit Board

The thermostat’s circuit board may malfunction if the batteries are new and the screen is still blank. A power surge or other issues could cause this since the board is responsible for powering the thermostat. The best way to troubleshoot this problem is to contact an HVAC professional to inspect and repair the circuit board.

Tripped Safety Switch

Residential and commercial HVAC systems have safety switches to prevent electrical overload, short circuits or unsafe situations. When this switch trips, the power to your thermostat will disconnect. To reset the safety switch, locate it and press the reset button.

Loose Wiring

The wiring in your thermostat may become loose over time, leading to a blank screen. Loose wiring could be due to an installation error, vibrations or normal wear and tear. Rodents could also chew on the wiring, causing it to become loose or disconnect from the thermostat.

If you’re experiencing a blank smart thermostat screen and suspect any of the above causes, you must find an immediate solution.
