10 Aug Why Your Thermostat Screen Has Gone Blank
The thermostat is a crucial part of your home’s HVAC system: you can’t control your air conditioning and heating without it! So if you go to your digital thermostat one day to turn on the AC or change its programming only to discover that the display screen showing a total blank, you’ll have a problem on your hands.
In some cases, you can fix the blank screen problem on your own; we’ll look at some of those situations. But there are others in which you will need the assistance of HVAC professionals experienced with working on thermostats. Sometimes, the best course is simply to have the whole unit replaced with a more advanced thermostat. (There are some great options with numerous features available today. Ask your technician about them.)
The first possibility to look into when you find a blank thermostat screen is to check if the unit needs to have its batteries changed. Not all thermostats use batteries; many are wired into the electrical system of the house. If you have a unit that uses battery power, remove the front plate from the wall plate and change the batteries to see if this brings the thermostat back to life again.
If the thermostat runs from the house’s electrical system, check on the circuit breakers. One of them might have tripped and cut off the power the thermostat. Reset the breaker. If this doesn’t work, then the issue with the thermostat could come from loose connections or other wiring problems. You cannot attempt to fix this yourself, so get in touch with an HVAC professional to come have a look at it. If the technician cannot locate a wiring issue at fault or find if trouble with the air conditioner or heater has trigged the power loss, then the best course of action is to have the thermostat replaced.
