  • Why Is My Thermostat Blank?


    If you’re like most Floridians, you’ll notice an almost immediate change in the temperature of your home if your thermostat screen goes blank.

    While a blank thermostat screen isn’t always a serious issue, it is something that should be addressed quickly to avoid future problems.

    If your thermostat is blank, here are the five common culprits.

    1. The Circuit Breaker Tripped

    Some thermostats are on the same breaker as other devices that draw too much power (like a hair dryer for example).

    If the circuit breaker trips, it may shut off the power to your thermostat, clearing the screen.

    If this is the case, fixing this problem requires nothing more than flipping the circuit breaker switch back on.

    2. The Batteries Are Dead

    Not all residential thermostats run on the home’s primary power supply. Many require batteries that need to be changed around once every year.

    If your thermostat screen has gone blank, and your thermostat runs on batteries, the first thing you should try is replacing the batteries with a fresh set.

    3. The Safety Switch Was Triggered

    In some homes, an air conditioner or furnace can trigger a safety switch and turn off the thermostat entirely if any damage has been detected.

    During the warmer months of the year when the air conditioner is being used, this generally takes place when there’s a water overflow in the condensate pan.

    As for furnaces, a safety switch can be triggered when the unit becomes too hot and damage is imminent. No matter why the safety switch was triggered, you should have your system inspected immediately.

    4. There Are Loose Connections or Wiring Problems

    There are lots of connections within your thermostat. These serve various functions — from the screen display to how the device communicates with your air conditioning system.

    Unless you have an electrical background, we don’t recommend fiddling with any loose connections or wiring problems yourself.

    5. The Thermostat Needs to Be Replaced

    If all else fails, your thermostat might simply need to be replaced. All thermostats are different, but the average device has a life expectancy of around 10 years.

    If yours is up there in age, check with your local HVAC professionals to see whether or not your thermostat needs to be replaced.
