ecobee's reset article explains the options on the thermostat: go to Main Menu, Settings, Reset, and choose what to reset. Reset All returns the thermostat to factory settings, which means you must set it up and register it again; heating and cooling settings are lost and a technician may be needed to reconfigure them. Other options reset only the Wi-Fi, the schedule or the preferences, which is gentler when only one thing is wrong.
The checks in more detail
Before Reset All, write down or photograph your equipment settings under Installation Settings. If you are selling or moving, unregister the thermostat from your account, using ecobee's register and unregister article, and follow the move and transfer ownership article, since a registered thermostat cannot be added by a new owner. If you have changed homes, changed wiring or replaced the HVAC system, ecobee has a reconfigure article, which may be all you need instead of a reset.
A reboot is different: it restarts the thermostat and keeps settings, and is the first thing to try for a frozen or offline thermostat. After a reset, give the thermostat time to learn and set up sensors again. If the thermostat will not reset or boot, contact ecobee support. Photograph your settings screens first, since rebuilding them from memory is slow. After a reset give the thermostat a few minutes to boot before starting setup. Do not reset in a heatwave or cold snap without a plan for comfort.
Before you reset a thermostat you are selling, unregister it from your account first, since a device still linked to you will block the new owner. A reboot, a Wi-Fi reset and a schedule reset are all gentler than Reset All, so try them in that order before losing your HVAC settings. If you only want the thermostat to forget wifi because you changed routers, reset Wi-Fi alone; a Reset All is overkill and turns a five-minute task into an evening of reconfiguring equipment.
Differential
Likely causes of “ecobee thermostats will not reset or needs to be reset safely”, and how to tell them apart
- 1
A frozen thermostat
What separates it The thermostat is unresponsive because it has frozen in an odd state

- 2
A bad wifi state

How to confirm Reset the schedule only, and then set up your comfort settings again in the app

How to confirm Unregister it and transfer it, so that the new owner can register it on their own account
- 5
New HVAC equipment
What separates it The heating and cooling behave wrongly because new equipment has been fitted to the system
How to confirm Reconfigure the equipment settings to match the new equipment, instead of resetting everything
