thermostat lcd screen blank brands

Your thermostat is the control center for your HVAC system. Programmable thermostats feature easy-to-read screens that allow you to program your heating and cooling settings and view the current temperature in your home. However, if that screen goes blank, you can’t do any of this. Honeywell and other brands of programmable thermostats typically show a blank screen when there is no power going to the wall unit.

A Honeywell thermostat will flash a low battery signal for about one to two months before the batteries in the wall unit run out completely. If you’ve been away or haven’t noticed this warning and the batteries can no longer provide power to the screen, it will go blank. This is easily fixed by removing the cover on the wall unit and replacing the batteries. You may have to reset the unit and reprogram your settings once the display returns.

If your thermostat is wired directly into your home’s electrical system, a blank screen indicates there is no power going to the unit, which means there may be a tripped breaker or a problem with the wiring. If the breaker controlling the unit hasn’t tripped, contact an HVAC technician or an electrician to inspect the wires. Sometimes a loose connection is enough to stop power from running to the unit. If this doesn’t resolve the issue, have the thermostat replaced.

Your thermostat is important. It is the one device that can control the temperature in your home. That being said, it can be more than a little concerning when you go to turn on your AC and find a blank thermostat.

However, most of the time, a thermostat blank screen can be easily fixed if you can find out what caused it. Here are some possible causes of a blank thermostat and how to fix it.

Before you jump to conclusions, make sure the thermostat isn’t just turned off. If you don’t live alone, there is always the chance that someone else turned it off by accident and there is nothing to worry about.

Some thermostats automatically adjust their screen’s brightness level when there is too much light in the room to save battery power. Be sure to check and see if your thermostat is at a lower brightness before you move on to other potential causes.

Another common cause of a thermostat blank screen is dead batteries. If your blank thermostat runs on batteries, try replacing them – and see if that turns the thermostat back on.

If you own a Honeywell thermostat, the blank screen could be an indication of a furnace door that wasn’t completely closed. These thermostats are programmed to shut off entirely if a furnace door is open. To rule this out, double-check to make sure your furnace door is fully closed.

Most thermostats are connected to a home’s main electrical system. If this is the case, it’s possible that the thermostat or some other electrical device caused the breaker to trip. Go to the breaker, and flip the switch to reset the circuit. If the screen turns back on, you found the cause.

Sometimes, the issue is with your AC itself. Every AC has a safety switch installed in the drain pan that turns the system, thermostat included, completely off if it detects a hazardous problem. If the safety switch indicates a problem, contact an HVAC professional to inspect your AC.

It is always a possibility that your thermostat has reached the end of the road and needs to be replaced. Most thermostats last around 10 years. Therefore, if your thermostat has been around a while, has a blank screen and isn’t working, it may be time for a new one.

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.

Is your Honeywell Thermostat screen not responding? You are not alone! That seems to be one of the common problems with Honeywell thermostats and other brands.

However, it doesn’t mean your thermostat is faulty whenever this happens. Sometimes, the screen may stop responding when the batteries are low or bad, or when the circuit breaker trips off.

So if your Honeywell thermostat screen is not responding, you want to keep reading as this post contains valuable information for you. Let’s head right into it!

When your thermostat screen goes blank and is not responding, it becomes near impossible to program your heating and cooling settings and also view the current temperature in your home. Sometimes, this issue doesn’t require an HVAC expert, so you can attempt to fix it yourself. And here are some troubleshooting steps to try if your Honeywell thermostat screen is not responding.

When your Honeywell thermostat screen stops responding or creating fading digits, the first place to look is the batteries. The batteries may be drained out or bad, causing the screen not to respond as well as it should. This is especially true if your thermostat is running completely on batteries.

A quick fix: replace the batteries and get your baby back in shape. However, make sure you replace all the old batteries with newer ones. Trying to mix the old batteries with a few new ones will still leave your screen as dead as before.

This is another common reason the screen of many Honeywell thermostat users stops responding. There may be a loose wire on the back of your thermostat, and your thermostat needs all wires properly connected before it can communicate well with the screen. However, you can fix this on your own too—no special skill or technical know-how is required!

To check for any loose wire at the back of your thermostat, remove its cover. Next unscrew the system from the wall, and you will see a bundle of thin wires located just at the back of it. Check to see if any of these wires are loose, so you can put them back in place. You should get your screen working properly again after fixing the loose wire.

Most HVAC systems come with their own circuit breaker, and during a power outage or power surge, the circuit breaker can trip off. When this happens, it can cause your Honeywell screen to refuse to respond. So, check the circuit breaker to be sure it is not tripped. If it’s tripped, manually flip it off and then on again.

Remove the unit from the wall and carefully remove the casing that covers the touch screen. Now, move the tabs on either side simultaneously and outwards to remove the circuit board. You will find two small ribbon cables plugged into the circuit board. Be careful with these because they are very fragile.

One of the cables is marked for the touch screen while the other for LCD. There are two small tabs on either side of the cable. Slightly pull it up and back to ensure it is fully seated. This should bring back the display screen but don’t forget you need to be extra careful with the cables because they are fragile.

This may not be the solution you expect to see, but that is likely going to be your only option when you have tried everything mentioned above, and nothing seems to work. It shows that your Honeywell thermostat may be faulty and so you will need to replace it with a new one.

And on the one hand, you may want to have an HVAC technician examine the faulty thermostat to see if it can still be fixed. If not, you should get a new thermostat.

There are several reasons for this. If your thermostat runs on batteries, maybe your batteries are dead. But if it is wired into the house’s electrical system, it might be some wiring issues causing your thermostat screen to go blank. Check the steps highlighted above to fix it.

As mentioned, one major reason the Honeywell Thermostat screen goes blank is when the batteries are drained out and can no longer supply power to the screen. Your batteries may drain out without notice—especially if you have been away for too long.

To reset the thermostat even when the screen is blank, you will have to replace the batteries. Remove the cover on the wall unit and replace the batteries. The display should come back on immediately after you replaced the batteries.

Though some cases of a ‘thermostat screen not responding’ may require a replacement, it doesn’t happen all the time. You could easily fix the bug yourself sometimes.

Picture this: You walk up to your thermostat to adjust the temperature in your home, only to be greeted by a blank screen. You tap on it and press the buttons — still, nothing. Since your thermostat is the control center for your HVAC system, you can’t afford to go too long without it working properly.

Remove and replace the batteries from your Honeywell system as directed in the instructions for your specific model. The batteries may be within your battery compartment or control panel. Be careful to make sure they are correctly oriented within the thermostat. Once replaced, test the system for operation and responsiveness.

Imagine you’re waking up on a cold California winter day and you decide to turn the temperature in your house up to get a little warmer and you discover the thermostat won’t work. You wonder why is my thermostat blank even though I haven’t lost power? Being that your thermostat is the command and chief for your entire home’s air system, it is crucial that the problem gets solved, whatever that may be. It is important because there may be a bigger underlying issue that needs to be addressed. Here are some of the thermostat options out there and what we recommend:

Standard non-programmable thermostats such as the Honeywell thermostat and Totaline thermostat and the Trane thermostat brands (which also make smart thermostats) generally have no issues with them other than battery replacement and dust piling up. Although these are the least expensive thermostats fairly simple to use, this is the least energy-efficient model. When you modify the thermostat because of the outdoor temperature changing, you have to constantly go back and forth with it to adjust and readjust.

Programmable thermostats such as the brands listed above as well as Google, Ecobee, and Bosch often have issues such as batteries or drawing too much power when they are using the same power source as a big appliance (tripped circuit breaker). Some programmable thermostats don’t send notifications when the power supply is off, which is a larger issue for homeowners relying on that information to ensure there isn’t an emergency within the home that needs to be tended to. Overall though, programmable thermostats prolong the life of your heating and AC system and can save you up to 30% of your costs lost from energy efficiency.

Smart thermostats learn the behavior patterns of your home (when people are home versus when they are not). They can also detect weather patterns and if there are any major issues with your HVAC system, notify you right away. By using Wifi technology, you can control from your smartphone, computer, or tablet all of its actions. These thermostats can adjust themselves. Although these are the most expensive thermostats, they are the most energy-efficient option. With this technology can come some issues that usually can be fixed with a minor adjustment. Rarely, they can produce faulty analytics on your home heating and cooling habits. These are the thermostats we recommend.

The thermostat can be reset by power cycling.  Power cycle the thermostat by removing if from the subbase and remove the batteries (some thermostats will not have batteries). Wait 10 seconds and then replace the batteries and place the thermostat back on the subbase.

The Pro1 professional thermostat systems are designed to give you the best technology of today and the flexibility for easy upgrading in the future.  Our innovative design always has the same footprint so you never have to worry about wall marks to repair if you upgrade to a new model.  Your Heating and Air Conditioning technician can help you upgrade.

Auto-changeover is a feature on some of our models that automatically selects heating or cooling based upon your program settings.  The user sets the program for heating and for cooling and then put the thermostat in “Auto” mode on the system switch.  The thermostat will then use the programmed settings to turn on heating or cooling as needed.

Many Pro1 programmable thermostats have a morning recovery feature that will turn on your heating or cooling before the start time of your wake program so that the room temperature is near your wake set point temperature at the time you selected for the wake time period.

Some Pro1 thermostats have built in delays that will last for 5 minutes or longer before heating or cooling is turned on. One reason this feature is used is to help protect your system against short cycling.  Your heating and cooling professional knows how to use these features to your best advantage.

Some Pro1 thermostats have a built in minimum run time feature that will make sure your system always runs for at least 5 minutes every time your system turn on.  This feature is often used to help remove humidity and to keep your system from turning on and then off too quickly.

Our programmable thermostats have an override feature that lets you override the program temporarily or permanently.  Your thermostat will be in permanent override if you press the up or down temperature keys and then press the “hold” key. You will notice the word “hold” near your setpoint and now your thermostat will stay at your setpoint temperature until you press “run sched” or turn the system switch to “off”.

Your display will be blank except for the low battery icon as a final warning to replace the batteries. You should replace the batteries immediately. Your display will return to normal operation after the batteries are replaced.

Some Pro1 thermostats will turn off the display light when the batteries are getting low. The display light will return to normal operation after the batteries are replaced.

Open the door on the front of the thermostat.  Replace with 2 high quality AA Batteries (Duracell or Energizer).  If you don’t see batteries behind the door on the front, pull the thermostat off its sub-base with a firm tug to access the batteries at the back of the thermostat.

If your installing contractor has configured the thermostat to remind you when your filter needs to be changed, you will see “FILt” in the display when it is time to change your filter.

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.

At Trouth Air Conditioning and Sheet Metal here in Sulphur, Louisiana, we frequently field phone calls regarding thermostat issues.
