If your thermostat is blank, the first thing you should do is check the batteries. Chances are, the batteries have died and the thermostat simply can’t power on. Replace the batteries and see if your thermostat turns on. If not, proceed to the next step.

Typically, thermostats are connected to a home or business via the main electrical system. Sometimes, the thermostat or another source of electricity can cause the breaker to trip (similarly to how a hair dryer can trip the breaker for example).

If you’ve checked the batteries already, check the breaker. If it the breaker has tripped, simply flip the switch back on and check if this restores the thermostat screen.

Worst case scenario, your thermostat is at the end of its life and simply needs to be replaced. While all thermostats are different, the average device has a life expectancy of about 10 years.

It’s an “Oh no!” moment when you approach your home’s thermostat and see its screen is blank. Is it serious? Does it mean your furnace, heat pump, or air conditioning is broken? Not necessarily. In fact, most of the time, it’s something minor and can be easily fixed.

If your thermostat wall does not have a c-wire, or common wire, your thermostat most likely is not hooked up to your HVAC system for its power and needs batteries. When your screen is blank, it could indicate you need to replace the batteries. It that is the case, you typically need AA alkaline or 3-volt lithium batteries, but see what type is currently powering the thermostat and simply replace them. Most thermostats display a low-battery symbol when the juice is running low.

On the other hand, if your thermostat is hardwired to your HVAC system for power, it could be a temporary blank screen if the thermostat is in the middle of recharging. Wait a short time and see if the display returns. If it does not, read on.

Sometimes the wires hooked up to your thermostat are responsible for its lack of power. If they were not firmly attached originally or the thermostat is in a high-traffic room, the vibrations from people walking by can sometimes affect the wires. Our technicians have also seen wires chewed by rodents in attics affect the wiring. Since wiring deals directly with electricity, we recommend you calling us to diagnose and repair the issue for you. When it comes to electricity, it’s better to be safe than sorry.

A quick fix to restore your thermostat’s power is a tripped circuit breaker or blown fuse, depending what you have in your home. Sometimes a surge can cause this issue. If you check your electrical box and a circuit breaker is tripped, just flip it back. If you have fuses, replace the fuse. Once this is done, check your thermostat. If you have power again, you are set; but if the breaker trips again or the replacement fuse blows, you have a more involved HVAC problem. You need to get a professional involved.

HVAC systems have built-in safety switches in the case of an unsafe situation. In the event a safety switch on one of your units is tripped, the transformer supplying voltage to your unit (and possibly your thermostat) will stop power. If this is a furnace, you need to call in a professional for a diagnosis and repair. If it’s your heat pump or air conditioner, check its condensate pan to see if it’s full. As a safety precaution, this will trip the safety switch. Empty the pan and see if power is restored to your unit and thermostat. If not, you need a professional.

Every once in a while, our technicians come across this issue. Some thermostats are more sensitive to this issue than others, but it is something worth checking. If your furnace door is not closed tightly, your thermostat will turn off. Simply closing the door securely should restore power if this is the cause.

Though thermostats can last 10 to 20 years, they do wear out. Sometimes it is just time to replace it. If your thermostat is older, unfortunately this may be the problem. If it is, be sure to have a professional install the new one, since the newer ones can be complicated, and you want to be sure you will not have issues with it in the future.

A blank thermostat screen is scary for any homeowner, especially in the middle of winter or the heat of summer. Is it simply a matter of replacing the batteries? Is there faulty wiring somewhere? Or is it something that’s going to cost you major bucks? Maybe your whole HVAC system is broken, and you’re going to need to replace it all!

Don’t panic. If you have a blank thermostat screen, there may be a simple solution to your problem. Here are some of the most common reasons why your thermostat screen might be blank – as well as ways to fix it.

Does your HVAC system have a power switch that can be turned on and off? If so, the switch should be turned to the “on” position. Some thermostats will turn off when your air conditioner is off.

Honeywell thermostats are particularly sensitive to this issue. If your furnace door isn’t fully and securely closed, the screen on your thermostat might appear blank.

Many programmable thermostats allow you to change the brightness setting. If your settings are too low, it might seem like you have a blank thermostat screen. Some thermostats, including the most popular Honeywell thermostats, will dim the screen at a certain time (typically very early morning) to avoid burn-in. Wait and see if the screen brightens again.

Some thermostats require battery power, and if the battery dies, your screen will go blank. Try changing the batteries. Clean the battery contacts with a pencil eraser and gently pry out the spring contact so you get the best connection.

Smart thermostats like the Nest use the wires connecting the heating and cooling system to recharge. But if the battery drains down, you’ll see a blank thermostat screen (or possibly a blinking light) as it recharges. Once it’s recharged itself, you’ll be good to go. If this happens on several occasions, some component of your HVAC system may be broken. The thermostat would need to use more power than usual. In this instance, have your HVAC system checked by a technician.

Faulty wiring could be the problem, especially if you’re having trouble right after installation. Thermostats from Wiser Air, for example, require a C terminal, so you might need a special wire extender. Most thermostats need a 24 VAC power supply. If the thermostat was hooked up to 120V or 240V power for any length of time, it could be damaged.

If you blow a fuse on the furnace control board, your thermostat won’t work properly. Open your furnace control panel and check the connection between your thermostat wires. Look for a purple 3-amp or an orange 5-amp fuse on the board, and check that it’s intact. If it’s blown, you have to replace it. You can read more here about why your air conditioner might be causing your fuse to blow.

Furnaces have high-limit switches to keep them from overheating. If your screen goes blank after several minutes of heating, it could be because the high-limit switch is tripping. This is commonly due to restricted airflow because of broken or dirty parts in the HVAC system. A failing fan motor can cause your electrical components to pull in more amperage than usual, tripping the high-limit switch. Any of these could cause a blank thermostat screen.

If your drip pan fills up, it can activate a float switch which will cut power to your HVAC system. When your drain line does not empty outdoors, it could cause a blank thermostat screen. If you’ve tried rebooting the thermostat and changing the batteries, don’t forget to check the drain pan. Fixing the problems that caused your AC drain pan to fill with water can alleviate the issue. Refer to your manual to see if you need to reset the float switch.
