At my house, the Honeywell Thermostat is the most often utilised device; when the kids get home from school on a hot day, they crank up the air conditioning.
It also plays in the background whenever we have visitors since my pals enjoy having a nice breeze blow through their hair.
My thermostat has crashed a few of times as a result of this continual manhandling. The only positive aspect is that when it crashed, I learnt how to care for it.
There have been instances where the thermostat’s display was blank and it would not turn on.
To get my Honeywell Thermostat to operate again, I realised I needed to learn how to reset it.
I’ve scribbled down the reset techniques for every Honeywell Thermostat series models that you might have in this post.

What Is Wrong with My Honeywell Thermostat?
Several difficulties can be resolved by resetting your thermostat, including:
- Programming issues with your thermostat
- You’re having trouble connecting to your furnace or air conditioner.
- Temperature readings that are inconsistent or imprecise
What Honeywell Thermostat Do I Have?
You’ll need to know the model of your thermostat to reset it. Your model number will be written on the product package or the thermostat ID card if you still have them. Remove your thermostat from the wall and look for the product number on the back of the wall plate if you don’t have the box.
Without using any tools, most thermostats may be gently pulled from the wall. Pull from both sides of the thermostat evenly. If it won’t come off, you’ll have to look for models that look similar to your thermostat online.
How to Reset a Honeywell Thermostat?
A thermostat reset can be done quickly with battery-powered thermostats. Here’s how to do it:
Caution: Some of these thermostats are wired directly into the home’s electrical system. If you can’t figure out what type you have or aren’t familiar with working with household wiring, consult an HVAC professional before attempting any repair that might expose you to the wiring.
- Turn it off and Remove the batteries from the thermostat.
- Negative to positive and positive to negative are the inappropriate ways to put the batteries in.
- Wait five seconds before rearranging them in the proper order.
- The factory settings for your thermostat will be restored. Make sure your thermostat is set to your typical schedule.
- Batteries aren’t used in all Honeywell thermostats. Those who don’t are hardwired into the electrical system of the house. Check out this helpful website for instructions on how to reset thermostats that don’t require batteries.
How to Replace a Honeywell Thermostat’s Batteries
If your device requires batteries, they are simple to replace. Don’t be concerned if your screen appears dim or goes black until you replace the batteries. This is how you do it.
- Remove the thermostat’s faceplate. With even, forceful pressure, most thermostats will just turn off. On the top and bottom of some models, there are little tabs. A quick inspection should reveal whether or not your model has tabs.
- Remove the old batteries from the system. The unit may accept AA or AAA batteries, depending on the model. Check the size of the batteries you’re replacing to be sure they’re the proper size.
- In the battery compartment, place the fresh batteries.
- Replace the faceplate on the backplate. The thermostat display should turn back on once it’s been reconnected. Select the Menu or Program key, depending on your Honeywell model, to confirm that any programmed settings are still recorded correctly.

How to Get a Honeywell Thermostat to Unlock
The steps for unlocking your Honeywell thermostat vary depending on which Honeywell model you have. However, the procedure is similar for most Honeywell models. To limit how many family members can control programming or alter the temperature, most users will need to lock or unlock their thermostat.
- Enter 1234 using the Center or Menu button.
- You’ll be able to establish a passcode if this is your first time setting up your thermostat. This number should be saved somewhere you won’t forget it, such as your phone.
- To prevent access to adjusting the unit’s temperature or reprogramming it, select the Lock option.
My Honeywell Thermostat’s Passcode Has Been Forgotten
There is a workaround for this, so don’t worry!
- Repeat the first step of the previous instructions. Continue with the steps below if you get an error or an inaccurate warning while entering the number 1234.
- The thermostat should be removed from the base plate. A four-digit date code can be found on the back of the thermostat.
