No one wants to come home to a blank thermostat, especially in the middle of a hot Florida summer. Your thermostat is a small, but crucial part of your HVAC system. If the screen is blank, you can’t program your cooling and heating settings.
Although a blank thermostat can indicate a more serious problem, sometimes it is a minor issue that can be easily fixed.
So, what does it mean when your thermostat goes blank?
5 Common Reasons Your Thermostat Display Is Not Working
1. Dead Batteries
While some thermostats are wired in with your home’s electrical system, other thermostats are battery powered. If you have a blank thermostat that is battery-powered, you may simply need to replace the batteries.
2. Tripped Circuit Breaker
Sometimes your thermostat is on the same breaker as other devices, which can result in circuit breaker trips. When the circuit breaker trips, it can power off your thermostat, giving you that blank screen. You can try resetting the breaker, but if this doesn’t solve the issue, your thermostat could have wiring problems.
3. Wiring Problems
Your thermostat operates from many connections. These connections serve many functions, including screen display. If wiring problems are at the root of your thermostat issue, your local HVAC professional will need to fix it.
4. No Power to Thermostat
Does your HVAC system have a power switch? It’s possible that your HVAC system is switched “Off”, which will also shut off power to your thermostat. Make sure the power switch is in the “On” position.
5. Your Thermostat Needs to be Replaced
Did you know that the average life expectancy for a thermostat is ten years? If yours is much older than that, you’re due for a replacement.
Contact your local HVAC professionals and they will let you know if your thermostat needs to be replaced.
