Honeywell Thermostat Display Not Working
If the screen goes completely blank, this might be due to a technical fault. If some of the numbers/info go missing, this might be due to a wiring issue. And if the numbers are displayed but they are not readable format, this might be due to dead batteries or any other technical fault. Let’s discuss these scenarios in detail for a better understanding. ..
Reasons why the display isn’t working: –
Low Brightness Display
Some people have reported that their displays have gone faulty after their thermostats adjusted themselves to low brightness mode in response to bright light in the room. So, it’s important to check if this is the case before assuming anything. ..
Old Batteries
If your device is not working, the first thing to do is check if the batteries are still good. If they are not, you can try to replace them with new ones. ..
Improperly Closed Access Door
A possible reason for the blank screen on the HVAC system could be that the door to the furnace was not properly closed when the system was turned on. This could lead to air being unable to reach the furnace, and as a result, the screen will show an empty space.
Broken Circuit
A fuse wire is provided in every electric circuit meter of a house in order to protect the circuit from excessive load and heat. If the fuse wire is burnt, this can lead to the breaking of the circuit. ..
Safety Switch Turned off
An electrical safety switch is a safety feature found in many appliances, like air conditioners and heaters, to protect the users from any accidents or unfavorable situations. If there is a possibility of damage or fault, the switch will turn off automatically and stop the appliance from running. ..
What to do to solve the issue & make the display work again?
Replace the batteries
This is a simple solution that can help you fix the device.
Check the door
As already discussed above, one can open and try closing the furnace door again to check that the power has been cut off.
The problem is technical, and we need to find a way to fix it.
Call the electrician
If you have an electrician come to your house to check the wirings and if there is an issue with them or with the fuse wire or your appliances, try restarting the thermostat.
Contact Customer Support
If there are no problems with the wiring, contact Honeywell’s support team and they will suggest whether the problem can be troubleshot by their solutions or they will need to send a thermostat technician to detect the device. ..
Buy a new device
If you have an old thermostat that is not working properly, it is best to replace it with a new one. If the device is in the warranty period, a new one can be requested from the company but, if it is older than 10 years, it’s better to replace and buy a new one. Usually, the shelf life of a thermostat lies around 10-15 years.
If your thermostat doesn’t work, you can try to fix it by going to the Honeywell website and clicking on the “Technical Support with my products” option. Then select the tab “thermostats.” Click on the option that says “my device isn’t working.” Enter in the type and model number of your thermostat, and many troubleshooting ways will be suggested based on the problem. One can also call customer care and make a call. A technician will be sent to your house if needed based on the complexity of the problem.
There are many reasons why a thermostat’s display may not work. Some problems can be fixed on your own by resetting the device or changing the batteries, while others may require customer service from the company that made the thermostat. If nothing works, buying a new thermostat is your last resort. ..
