As I faced the same problem in my home, I researched a lot on the internet to ask customer support but finally, after talking to all of them, I learned some more things about Honeywell thermostats besides the problem I face in my thermostat and why my honeywell thermostat keeps turning off.

There is a wide range of thermostats that can be used at home.

Why your Honeywell thermostat keeps turning off and On

As I mentioned above in this article, There are several reasons why your Honeywell thermostat keeps turning off and on. I will tell you each and every reason why your thermostat keeps turning off.

There are many times when the Honeywell thermostat says heat on but no heat comes from the vent, it becomes so frustrating.

Similarly, When you are burning outside, sun hitting you with full power, you came home and turn your air conditioning and Honeywell thermostat not turning on ac.

Find out if your thermostat relates to these problems and take the required action to fix your thermostat.

1. WEAK BATTERIES

If you’re using battery-operated thermostats, then the most common reason thermostats start turning off and on by themselves is “Weak batteries”.

Insufficient charge in the battery causes your thermostat to keep turning off and on frequently. Battery-operated thermostats need sufficient power to keep your thermostat running efficiently.

If you forgot to charge the battery and your thermostat keeps running with a weak battery, it can affect your home HVAC system seriously. Have you ever thought about what could happen with a weak thermostat battery?

2. BLOWN FUSE

A blown fuse can also make your thermostat behave abnormally. A fuse is used in every electronic device to protect the device and wiring from overvoltage and short circuits.

When a fuse burns then the thermostat cannot operate efficiently. And make your thermostat go black sometimes or warn you about the fuse being blown with screen icons and some thermostats with an audio beep signal.

If you found any issue with the fuse then I recommend calling customer support service or changing it yourself if you can.

3. FAULTY WIRING

If the wiring in your home is getting an issue of short circuits or loose connections, then it can also be the reason why your thermostat keeps turning off and on frequently.

Loose wiring and faulty wiring should be checked on a monthly or yearly basis to keep your home wiring system future-proof. Also, check the thermostat connecting wire for any loose wiring in the thermostat.

4. DEFECT IN THERMOSTAT

Defect in thermostat

We all know that Honeywell always keeps its customer’s satisfaction its first priority. All the devices they make go through the quality check before dispatching to the warehouse.

But sometimes if they miss one by mistake then maybe it is yours. The chances of Honeywell thermostat getting manufacturing defects is less than 0.01%. And if you get one they will happily replace it with the new one.

If your thermostat is old enough to get some faults over time then you should call the support staff to fix it for you.

5. SCREEN BACKLIT LED FAULT

SCREEN BACKLIT LED FAULT

Your thermostat screen is lit up with the supporting backlit LED if they get any issues in the light then your thermostat looks like it turned off. The screen goes blank in this case.

To find out the backlit problem in your thermostat, check your HVAC system if they are working properly as scheduled then the issue is with your thermostat screen backlit.

You can also check by controlling your home HVAC system with your mobile app.

6. HEATING IN THERMOSTAT

HEATING IN THERMOSTAT

The thermostat controls your home HVAC system to maintain the desired temperature and if your thermostat works too hard to maintain the required temperature then your thermostat gets a little heat up.

If the temperature of your thermostat crosses the set limit, or the heater turns off by itself to save the thermostat. And when it cools down then it gets On automatically and starts maintaining your home temperature again.

7. SCREEN NOT RESPONDING

Screen not responding and screen freeze happens in some thermostats. If you notice that the screen freezes or the screen is not responding to your thermostat, then after some tries the thermostat starts restarting to refresh the system.

8. AUTO-UPDATING

thermostat auto updating

As thermostat keeps getting smarter they need to be updated to the latest version available. Honeywell sends Its update via OTA which needs to be updated to get all the features available in your thermostat.

Updating the thermostat required an internet connection and your thermostat must be connected to the internet while updating.

After the thermostat completes the update download it starts installing it immediately and while installing the update in your thermostat it restarts several times in-between updates.

What does short cycling mean?

Short cycling refers to a situation where your thermostat is turning your heating or cooling system on and off very frequently, rather than allowing it to run for a longer period of time. This can be caused by a variety of factors, and the solution will depend on the specific cause.

How do I stop my thermostat from short cycling?

Here are some steps you can try to stop your thermostat from short cycling:

  1. Check the thermostat settings: Make sure that the thermostat is set to the correct temperature range for your comfort level. If the set temperature is too far from the current room temperature, the system may be turning on and off frequently to try and reach the desired temperature.
  2. Check the air filter: A dirty or clogged air filter can restrict airflow, causing the system to work harder and potentially short cycle. Replace the air filter if it looks dirty or clogged.
  3. Check for air leaks: If your home has air leaks around windows, doors, or other openings, it can cause the thermostat to sense that the temperature is fluctuating, leading to short cycling. Check for air leaks and seal any that you find.
  4. Check the size of the heating and cooling system: If the system is too large or too small for your home, it can lead to short cycling. Have a professional check the size of your system to ensure it is correctly sized for your home.
  5. Check for thermostat issues: If you have tried the above steps and your thermostat is still short cycling, the problem may be with the thermostat itself. In this case, it may be necessary to have a professional check and possibly repair or replace the thermostat.

I hope this helps! If you have any further questions or are still having trouble with your thermostat, don’t hesitate to ask for additional assistance.

honeywell pro series thermostat blank screen

It’s possible that your Honeywell Pro series thermostat has a blank screen due to a number of different issues. Here are a few things you can try to troubleshoot the problem:

  1. Check the batteries: If the screen is blank, the first thing to check is the thermostat’s batteries. Replace the batteries if they are low or dead.
  2. Check the thermostat’s wiring: Make sure all the wires are properly connected to the thermostat and the HVAC system.
  3. Reset the thermostat: Try resetting the thermostat by pressing the reset button, which is usually located on the back of the thermostat.
  4. Check for power issues: If the thermostat is not receiving power, it will not function properly. Check the circuit breaker and fuse box to make sure the power to the thermostat is not disrupted.

If these troubleshooting steps do not resolve the issue, it’s possible that there is a problem with the thermostat itself. In this case, you may need to contact a professional HVAC technician for further assistance.

What is the lifespan of a Honeywell thermostat?

The lifespan of a Honeywell thermostat varies according to the type and how it is used and maintained. Most thermostats have a lifetime of about 10-15 years. Some higher-end models, particularly those used seldom, may survive longer.

It is critical to follow the manufacturer’s instructions for maintenance and care to help extend the life of your Honeywell thermostat. This may involve routine cleaning and battery replacement as needed. It is also a good idea to have a professional HVAC specialist inspect your thermostat and heating and cooling system on a regular basis to verify that everything is in working order.

If you are having difficulties with your Honeywell thermostat or are unclear of its age, it may be time to replace it.

What does it mean when your thermostat keeps blinking?

If your thermostat is flashing or blinking, there might be an issue with the thermostat or the heating and cooling system. The meaning of the flashing or blinking will vary depending on the kind of thermostat and the manufacturer’s instructions. Here are some possible causes of a thermostat flashing or blinking:

Low battery: If the thermostat is flashing or blinking and you have a low battery warning, it means that the batteries in the thermostat are running low and need to be replaced.

System error: If the thermostat is flashing or blinking and you do not have a low battery warning, it could be an indication of a problem with the heating and cooling system. In this case, you may need to call a professional HVAC technician to diagnose and fix the problem.

Thermostat programming error: If you have recently changed the thermostat settings or programmed the thermostat, it may be flashing or blinking as a result of an error in the programming. In this case, you may need to check the programming instructions and make any necessary corrections.

If you are unsure of the cause of the flashing or blinking on your thermostat, it is a good idea to consult the manufacturer’s instructions or contact a professional HVAC technician for assistance.
