Why Is My Thermostat’s Screen Blank in Myrtle Beach, SC?
Your thermostat is responsible for controlling your Myrtle Beach, SC home’s HVAC system, telling it when to start, stop, and what mode to use. When your thermostat screen goes blank, it’s often a sign of trouble. If your screen is blank, it’s likely due to one of these four issues.
You Have Wiring Issues
Your thermostat is an electrical appliance that typically includes a battery backup. If the internal wiring of your thermostat suffers damage, the screen usually goes blank. This is especially true if your battery goes dead.
You Have a Tripped Float Switch
Many HVAC systems have a float switch, designed to shut off your heating or air conditioning unit if moisture collects inside. If your thermostat screen is blank, you may have condensation inside, and the system shuts itself off to prevent further damage.
You Have a Tripped Breaker
Your thermostat is connected to the main electrical system. After the breaker trips, the screen will be blank if you do not have a backup battery. This can occur after a power surge or after you have been running more than one appliance at the same time.
You Need a New Thermostat
If none of the above issues are your thermostat’s problem, you may need a new thermostat. Most thermostats have an expected lifespan of around 10 years, depending upon the model of the unit. If your thermostat is more than a decade old and has a blank screen, it may simply be too old to continue functioning properly.
