Why Ecobee Thermostat Keeps Rebooting? Complete Fix Guide

Wondering why your Ecobee thermostat keeps rebooting? Wonder no further, because we will get it all enveloped for you by the end of this guide!

Here you’ll discover the true reason for the spontaneous reboots and how to efficiently put them to an end!

Your thermostat could be restarting during an update or if the batteries are weak. Reboots might also be initiated if the thermostat overheats, the screen overrides itself, or there is a scheduled reboot.

We cannot exclude the hardware yet, not unless you’ve inspected the wiring. With that being said, let’s take a look at the well-known reasons for Ecobee restarts and then how to stop them.

Why Does Ecobee Keeps Rebooting?

Ecobee might be rebooting due to several reasons. Either the battery is involved or the calibrating mode has failed.

Your thermostat would automatically restart if the calibrating fails, so you must make sure that everything is correct in the thermostat’s interface.

Here are some possibilities why your thermostat would keep restarting:

1. Battery Issue

If the battery has gone weak over time, even if charged, your thermostat might constantly reboot due to fluctuations.

2. Wirings Problem

A fault with the wirings in your thermostat’s configuration might also cause it to suddenly restart.

3. Ongoing Update

If the thermostat has rebooted a couple of times in the last two hours, it is possible that it is applying a larger update.

4. Schedule Issue

Scheduled reboots or auto-power saving features might cause your thermostat to reboot when inactive for longer than usual.

5. Blown Fuse

Lastly, a blown fuse in your furnace’s control panel might cause the thermostat some issues.

Now that we know what could be happening to the thermostat, let’s move forward on how to resolve the issue in a matter of minutes.

How To Fix Ecobee Thermostat Keeps Rebooting?

Before we proceed, it is good to determine if the thermostat is resetting due to bad weather or an outage in your area.

Any power fluctuations may reboot your thermostat, thus making the impression that the device is faulty.

Now, let’s take a look at some of the best solutions to fix an Ecobee thermostat that is restarting constantly.

Solution #1 Hard Reset The Thermostat

The first and easiest approach is to hard reset your Ecobee thermostat.

This process will actively discharge your thermostat out of any remaining electricity and provide it with a cold boot during the next startup.

Here is how to hard reset your Ecobee thermostat:

1. Turn off your thermostat by pressing the power button once.
2. Take the thermostat off the stand and unplug the “C” wire, which should be in red color.
3. Wait for 5 minutes and plug the wire back in.

Keep in mind that the circuit breaker must be flipped off to prevent any power shocks or life-endangering situations.

Solution #2 Clear Schedules

If you’ve included any reboots in your thermostat’s schedules, this might be the reason for this unfortunate issue.

Schedules can be edited from the Ecobee mobile app, where you can add a specific arrangement of features for your thermostat to perform during the whole day.

From there you will also be able to include heating/cooling modes, notifications, and restarts as well.

To edit the schedule, you must go to the Ecobee app > Settings > My thermostat > Schedules > Active and configure the active schedule from there.

To remove any restarts within the schedule, press the “X” button, next to the stated function!

Remove all schedules and if your thermostat keeps rebooting, move on to the next solution.

Solution #3 Change Blown Fuses

Another cause that might keep rebooting your Ecobee thermostat is a blown fuse.

The fuse would be located in the compartment of your furnace in a breaker-like box, where you will be able to unplug them and so on.

Here is how to change the blown fuses of your furnace:

1. Go to your furnace’s compartment and open the fuse box. (It is specifically for each configuration so only you would know where your furnace box is)
2. Once removed, take a good glance at all of your fuses and identify if any of them is damaged visually.
3. To replace blown fuses, you must flip the circuit breaker and unscrew the broken switch by rotating it to the left.

Once removed the fuse, you will be able to put a new one on its spot but it must be from the same thread.

Solution #4 Reconnect & Replace Wires

Now that you’ve identified potential blown fuses that might be restarting your thermostat, perhaps the fault is found within the thermostat’s wires.

Keep in mind that if the “C” wire you reconnected in the first solution is not plugged correctly, this might be creating power fluctuations, thus the thermostat will keep rebooting.

Here is a quick explanation on how to reconnect and replace your configuration’s wires:

1. Eject the thermostat off the wall by flipping the security switches on the side panel.
2. Once removed from the wall, you should see 3 wires.
3. Flip the circuit breaker and make sure each one of the wirings is tied around the power poles correctly.
4. Replace visually damaged wires.

Once reconnecting the wires, test out your thermostat to determine if it is still rebooting or not.

Solution #5 Prevent Overheating

Another big cause that might be making your thermostat reboot, is overheating.

Overheating could be caused due to several factors, including physical heat conductors and close proximity to one of them.

Here are some tips to prevent your thermostat from overheating and rebooting:

1. Make sure no direct sunlight is impacting your thermostat’s surface for too long.
2. Relocate the thermostat away from any household heaters or other type heat conductors.
3. Place your thermostat in a well-ventilated area and make sure the room’s warmth is always on an average level.

Once done with these steps, reset your thermostat for one final time to fix the issue.

Solution #6 Fix Calibrating Mode

Your thermostat would usually calibrate every time when rebooted/turned on.

If that calibrating process fails, however, your thermostat will keep rebooting until the calibrating succeeds.

Here are some causes that may fail the calibrating mode & how to fix them:

1. Make sure you’ve statedthe correct temperature for your thermostat to acclimatize in the mobile app’ settings.

2. Press the furnace’s power switch whenever turning the thermostat.

3. The furnace must be set to the same temperatures your thermostat would be acclimatizing.

Calibrating mode in conclusion would check if everything is set up with your thermostat’s interface. If the process fails, then you would know there is something wrong.

Solution #7 Reset The Thermostat

If nothing worked so far, then the easiest way out of the issue is via factory reset.

If there is something wrong with the thermostat’ software, a factory reset is your best shot at resolving the issue.

Here is how to factory reset your Ecobee thermostat easily:

1. Make sure your thermostat is running.
2. From the home screen, press the menu button and go to Settings.
3. Tap on “Reset”.
4. Choose to reset all settings of your thermostat.
5. Confirm and wait.

Your thermostat might take up to 5 minutes to complete the memory wipe and afterward, it should boot up ready to be set up.
