5 Tips To Try To Get Your Honeywell Thermostat Working Again

A few tips and tricks you may want to try to get your Honeywell thermostat to turn on include:

1. Replace the Batteries

You should start with the easy and obvious solution first. There is a chance your thermostat is not turning on because the batteries are dead. If you have a Honeywell thermostat that uses batteries, you may want to replace them with a fresh set.

Before you replace your batteries, you need to go to the circuit breaker and disable the power to the thermostat. After this, detach the thermostat from the wall plate.

This should reveal the batteries in the thermostat. Remove the old batteries in insert the new ones. Make sure you select batteries out of the right size and insert them in the appropriate alignment.

Once you are finished, put your thermostat back on the wall plate. Turn the power back on and see if the thermostat boots up. If it does, you have fixed the problem. 

2. Check the Air Filter

There’s also a chance that the thermostat is not turning on because there is something wrong with the air filter. If the air filter has been clogged, the air is not going to circulate appropriately through the vents. As a result, your air conditioner will not work properly, causing the thermostat to malfunction. 

If the air is not circulating in the right area, the thermostat is not going to generate an appropriate reading. This will influence when the thermostat turns on and want it does not.

If you want your thermostat to turn on, and you want to prevent your utility bills from spiking, then you need to clean and replace your air filters regularly. Your air filters need to be replaced every few months to a year depending on how often your AC runs. If you are not comfortable cleaning or changing your air filters, then you may want to call a professional for help. 

3. Check the Circuit Breaker

If your Honeywell thermostat is still not turning on, then you may want to take a closer look at the circuit breaker. You need to make sure there is power flowing to the thermostat. If there is no power going to the thermostat, then this is the reason why it is not working properly. You may want to try flipping the circuit breaker to restore power to the thermostat. 

After you do so, listen for a click. If your thermostat never turns on, then take a look at the circuit breaker again. If the power is off, then the circuit breaker is overloaded. You may need to change the way your devices are connected, so the circuit breaker does not keep tripping. If this is the case, you may need to call an electrician for help.

4. Check the Wiring for Any Loose Connections

If you are still having issues with your Honeywell thermostat, take a look at the connections. If the wiring is loose, your Honeywell thermostat may not have enough power. 

To check the wiring, remove the face of the thermostat. This should expose the internal wires. Take a look at the white and red wire. If you connect these two wires together, the thermostat should turn on. If you are not comfortable with this, you should contact an electrician for help.

When you work with wires, you need to take the appropriate safety precautions. You should wear safety goggles to protect your eyes in case you see a spark. You may also want to wear gloves to prevent yourself from being shocked. 

When you connect the wires, the thermostat needs to turn on. If the thermostat turns on, there is a problem with the way the thermostat has been programmed. Make sure the thermostat has been set at the right temperature. This may be the reason why the system is not working properly. 

If you connect the wires and the thermostat does not turn on, there is an issue with the wires themselves. If there is a problem with the wires, you need to contact a professional electrician. It can be dangerous to handle main wires, and you need to put safety first.

5. Reset Your Thermostat To Factory Settings

Another option you may want to try to get your Honeywell thermostat to turn on is to reset it to factory settings. The exact steps you need to follow to reset your thermostat to factory settings will vary depending on the thermostat you have. 

The goal is to completely flush any bad information out of your Honeywell thermostat by resetting it to factory settings. That way, it should run like it has been freshly removed from the package.

Then, locate the button titled “Program.” Press and hold the button down for several seconds. You may need to use a paperclip, a nail, or another object that has a sharp point.

  • Honeywell 6000 Series: If your thermostat falls under the Honeywell 6000 Series category, make sure the thermostat is turned on. Then, press and hold the “Fan” button as well as the “Up” arrow. Hold these for about five seconds, then release them. Press the button on the bottom left until you see “39” on the display. Press the down arrow keys until the number changes to “0” Finally, press the “done” key, and the thermostat should be reset.
  • Honeywell 7000 Series: If you have a Honeywell 7000 Series thermostat, you need to turn the thermostat off. Then, cut the power to the device. Remove the thermostat from the wall plate, and you should see two separate batteries. Remove them and insert them in the opposite direction for approximately 5 seconds. Now, put the batteries back in the right way once again. The display should turn on. Restore the power to the thermostat, and it should be completely reset. 
  • Honeywell 8000 Series: If your Honeywell thermostat falls under this category, press the “system” button on the screen. Then, press and hold the blank button in the center of the screen. Hold it down for approximately five seconds. There should be an option that says “reset to factory settings.” Select this option, and the thermostat should reset to factory settings. 

If you follow these steps, you should reset your thermostat to factory settings. This could be enough to flush any malicious code out of the system, allowing it to run appropriately once again.
