Is your Honeywell thermostat acting up and making your home feel like a sauna in summer or an ice box in winter? Maybe it’s completely unresponsive no matter how many times you press the buttons or scream at it out of frustration. We’ve all been there!
As a homeowner and HVAC enthusiast, I’ve had my fair share of thermostat troubles. Take the time my old Honeywell FocusPRO kept rebooting itself every 10 minutes. Or when my partner accidentally locked us out of the thermostat menu somehow while “adjusting the schedules.”
I was skeptical at first, but resetting my misbehaving Honeywell thermostats ended up being a quick DIY fix that saved me the hassle and expense of calling an HVAC technician. Now it’s the first thing I try when my thermostat is acting up or needs a good “reboot.”
In this handy homeowner’s guide, I’ll walk through the steps for resetting popular Honeywell thermostat models in 5 minutes or less. No tools or technical skills are required!
I’ll also share some tips I’ve learned over the years for troubleshooting common post-reset issues to get your thermostat working just the way you want it.

Preparing to Reset Your Honeywell Thermostat
Resetting your Honeywell thermostat can be a breeze, as long as you take a few steps to prepare first. This will make the process smoother and prevent any hiccups down the road.
Here are the key things every homeowner should do before taking the reset plunge:
1. Locate Your Model Number
First things first – you’ll want to dig up the specific model number of your Honeywell thermostat. Check the back of the device or inside the battery compartment for a model number like RTH6580WF or RTH9585WF.
Knowing the exact model lets you look up specific reset instructions and reprogram settings later on.
As a fellow homeowner, I can’t tell you how many times I’ve reset a thermostat only to realize afterward I had no clue which model it was! Don’t make my mistake – look up that model number ahead of time.
2. Record Customized Settings
Next, take a minute to jot down any customized heating/cooling temperatures or schedules that you’ll need to reprogram later. The standard times and temps are pretty easy to put back in, but any special adjustments you’ve made over the years can be tricky to remember.
For example, I have an unusual schedule that cools to 69 degrees at 8 AM before I head to the office. Definitely wouldn’t have remembered that one off the top of my head! So write down any weird settings you’ve programmed. Future you will thank you, trust me.
3. Quick Troubleshooting
Before resetting, try these basic troubleshooting tips to see if you can revive your misbehaving Honeywell without the reset:
- Replace old batteries in case the issue is just low power.
- Check wire connections to make sure they’re still secure.
- Do a manual restart if possible – just powering down can sometimes fix glitches!
If it’s still acting up after that, then you know it’s time to reset. But trying some quick fixes beforehand never hurts!
Steps to Reset a Honeywell Thermostat
Now that you’re prepared, it’s time for the fun part – actually resetting your misbehaving Honeywell thermostat. Follow these steps carefully and you’ll have that baby working well as new in no time.
1. Shut Off Power at the Breaker
First and most important – you need to cut power to the thermostat before resetting it. I simply flip the breaker switch that controls my HVAC system off for 1 minute. This gives the thermostat a clean slate.
2. Remove the Faceplate
Next, pop off the decorative faceplate of your thermostat. Don’t worry, they’re made to snap on and off easily. This exposes the more technical interior so you can access the reset button.
If you’re unsure how to remove the faceplate, consult your model’s manual for a diagram. I’ve found the faceplates usually either slide up and off or swing open like a little door.
3. Press and Hold the Reset Button
Here comes the actual reset! Locate the recessed reset button on the interior panel of your thermostat.
It’s usually labeled and may have a “Reset” indicator near it. Press and hold the button for 5-20 seconds until the display goes completely blank.
4. Replace the Faceplate
Snap the decorative faceplate back onto your thermostat after the reset is complete. This makes it look nice and tidy again for the reprogramming.
5. Turn Power Back On
Lastly, head back to the breaker and switch the power back on now that the reset process is finished. The thermostat display should light back up, ready for you to re-enter settings.
Re-entering Your Settings
The hard part’s over – now it’s just a matter of reprogramming your Honeywell thermostat with your desired temps and schedules. Here are some tips to make it quick and painless:
- For basic programmable models, just follow the on-screen prompts to re-enter your weekday/weekend heating and cooling temps for each time period. Easy!
- If you have a WiFi-enabled model, reconnect it to your wireless network using the app or web portal. This syncs your customized settings.
- For advanced models like Pro, FocusPRO, or Lyric, the app makes reprogramming a breeze. Just connect and your unique info will be pulled in.
- Don’t remember the exact temps and times? Check the photo you took of your old settings (you did take one, right?).
- If needed, refer to your manual for step-by-step instructions specific to your Honeywell model number.
- For any third-party smart home integrations, you may need to reconnect those as everything gets a fresh start.
Take your time here, double-check your work, and you’ll be back up and running in no time!

Troubleshooting Common Reset Issues
Resetting your Honeywell thermostat is usually quick and seamless, but occasionally minor issues can come up. Here are some quick fixes:
- If the reset button doesn’t respond, try a 30-second hold or use an alternate reset method like disconnecting wires.
- Let the thermostat fully reboot before reconnecting power if the display freezes post-reset.
- For connectivity problems, double-check your WiFi password and router connection.
- If you’re locked out from too many incorrect password attempts, you may need to disconnect and reset again.
- Error messages on the screen after resetting? Look them up in your model’s troubleshooting guide.
- For any problems persisting after resetting and troubleshooting, it may require a call to a technician
Resetting your misbehaving Honeywell thermostat really is as straightforward as that when you follow the proper steps. Just take your time and don’t skip any preparation work.
While it may seem intimidating, I can assure you that the reset process is something any homeowner can tackle themselves.
Give the ol’ reset button a try and there’s a good chance you’ll get your thermostat back on track. Just be sure to record any important settings so you don’t lose your customized schedule.
