Honeywell Thermostat Screen not Responding (How to Fix)

Honeywell thermostats are an essential component of any modern home. Not only do our thermostats help to keep your home at a comfortable temperature.

Even smart thermostats have many advanced features that help to improve energy efficiency.
However, occasionally, homeowners may experience an issue where the Honeywell thermostat screen is not responding.

As per the ENERGY STAR, a smart thermostat can save an average of 8 % on your heating and cooling bills. It means if your thermostat does not work properly, there will be an increase in your utility bills.

Honeywell thermostats occasionally encounter technical issues, just like any other electronic gadget. Low batteries, loose wiring, or problems with the thermostat are just a few possible causes of these technical troubles. By checking the batteries and other parts of the thermostat and resetting the thermostat, you can mostly resolve these problems.

In this blog post, I’ve discussed the possible issues and solutions why Honeywell thermostat screen not responding . You can fix the problem with the help of this blog post. Additionally, this post will offer advice on how to stop it from happening again.

Honeywell Thermostat screen not responding (How to Fix)

By following these troubleshooting steps, you can ensure that the Honeywell thermostat will continue providing accurate temperature control for years.

Check the circuit breaker

If your thermostat screen is unresponsive, one possible reason is that a circuit breaker has been tripped. You can check your breaker box and make sure that the thermostat switch is in the “Off” position.

If you see it is off, flips it back to the “On” position and wait a few minutes to see if the screen comes back on. However, checking the circuit breaker is an excellent first step in troubleshooting an unresponsive Honeywell thermostat.

Check the batteries

The second cause may be that your Honeywell thermostat batteries are not charged or are low. If they’re weak or dead, this can cause problems with their responsiveness on screen. It may either go blank or become completely unresponsive.

Steps for checking the batteries:

• The batteries for the Honeywell thermostats are located in the back of the unit. To access them, remove the front cover by gently pushing on the tab at the top of the body and then sliding it off.
• With the cover off, you will see two batteries in a holder on the back of the unit.
• Unscrew the retaining screws and remove the old batteries to replace them.
• Then insert the new batteries, being sure to observe the correct polarity, and screw the retaining screws back in place.
• With fresh batteries in place, your thermostat should be up and running again.

Check the wiring

The wiring could be another factor preventing the Honeywell thermostat screen from responding. The screen may stop working if the thermostat wiring is damaged or loose.

Steps to check the wiring

Here are a few simple steps you can follow:

• Firstly, disconnect your thermostat. Turn off the power of the thermostat at the breaker box.
• A cover or panel should give you access to the wiring. You can refer to the owner’s manual for wiring for your specific model.
• Next, remove the thermostat faceplate from the wall. You can match the sticky tag on the wire to the terminal.
• If you find any wire is loose, you can gently slide the wire into the terminal hole until it clicks into place.
• Check all the wires are connected to the terminal. There is no wire hanging loose.
• Later, reassemble the thermostat and turn on the power at the breaker.
• Finally, check if the screen is working fine.

This way, you can quickly ensure your Honeywell thermostat is working correctly by checking the wiring and following these easy steps.

Check for a power outage

Honeywell thermostats are designed to be reliable and easy to use. However, power outages can impact the Honeywell thermostat screen in several ways.

First, the Honeywell thermostat may lose its connection to the power grid. This can cause the Honeywell thermostat screen to go blank or display an error message. In addition, a power outage might prevent the Honeywell thermostat from maintaining its settings.

As a result, the Honeywell thermostat screen might have a lower temperature setting by default or might not let you change the setting at all.

Finally, power outages can also cause the Honeywell thermostat screen to dim or flicker. While these issues can be frustrating, they are usually temporary and will be resolved once power is restored.

Check for Air filter

Most homes have a Honeywell thermostat controlling their heating and cooling. Typically, these thermostats will have an air filter that needs to be checked and replaced regularly.

Checking the air filter is a simple process that only takes a few minutes. The thermostat may be unable to accurately read the temperature if a dirty air filter covers the sensor.

Steps for checking Air filter

• First, locate the filter cover on the thermostat. This is typically found on the side or back of the unit. 
• Once you have located the cover, remove it to access the filter. 
• Inspect the filter and look for any dirt or debris that may have built up. If the filter is filthy, it will need to be replaced. However, if it only has a small amount of debris, you can clean it with a soft brush or cloth. 
• After replacing the filter, clear the screen by touching “dismiss”.
• Be sure to reinstall the filter cover before turning the thermostat back on. 
• Once you have cleaned or replaced the filter, test the thermostat to see if it is now working correctly. 

Make sure furnace door closed

Have you ever gone to turn on your furnace only to find that the thermostat screen is unresponsive? If so, the first thing you should check is to ensure that the furnace door is closed securely. If the door is improperly sealed, the screen may freeze, giving the thermostat sensor a false reading.

To fix this problem, open the furnace door and ensure it is properly aligned. So, the next time you turn on your furnace and the thermostat screen is unresponsive, check that the door is entirely closed before doing anything else.

Old Thermostat

One of the most common issues with older thermostats is that the screen stops responding to touch.
Sometimes an old thermostat will catch dirt and dust on the screen. Over time, the build-up can become so bad that it affects the screen’s sensitivity.

As a result, even light taps may not register. The best way to clean an old thermostat screen is to use a soft, dry cloth. You can gently wipe the screen in a circular motion until all the dirt and dust have been removed.

The screen can be cleaned with a gentle cleaning agent like soap and water if required. Avoid using solutions that contain alcohol or ammonia, as they can harm the screen. With a bit of regular cleaning, you should be able to keep your old thermostat working like new for many years to come.

Restart the Thermostat

Next, you can check if the above solutions don’t work, you may need to restart your Honeywell thermostat. To do this, turn off the power to the unit at the breaker box and then turn it back on again. Once the power is restored, your thermostat should start working again.

• First, locate the reset button on the front of the thermostat. It will usually be recessed, so you may need a paperclip or other small object to press it.
• You can hold the reset button down for three seconds.
• The thermostat will power down and then reboot. That’s all there is to it!
• Rebooting should clear any errors and allow the thermostat to function properly again.

Wrap up: Honeywell Thermostat Screen not Responding

It can be frustrating and challenging when your Honeywell thermostat screen isn’t responding. When you won’t be able to adjust your home’s temperature or settings quickly, you may feel uncomfortable or be in danger of being over-heated or under-heated.

Fortunately, there are several steps that you can take to troubleshoot and resolve this issue. Start by checking your thermostat’s power supply, as this may be a case of a drained battery. By looking at the wiring behind the thermostat, you can ensure everything is linked correctly.

You might have to completely reset or replace the thermostat if these options don’t work. I hope, with some basic troubleshooting skills and persistence, you should be able to get your Honeywell thermostat working again quickly.
