A thermostat is necessary whether you want to keep your home warm or cold since it helps to manage the temperature according to your choices. Additionally, the Ecobee thermostat aids in bringing balance to your heating and cooling requirements, which improves energy efficiency.
Here are some pointers to help you operate your Ecobee thermostat effectively and resolve any possible problems, such as your Ecobee thermostat not coming and other types of malfunction you might experience.
This Page has solutions in detail, that will help you fix your ecobee. The causes of this problem are discussed first before the solutions are provided. Read carefully
The primary cause of your thermostat’s malfunction is a lack of power connectivity. Nevertheless, the reason for the power problem may differ based on whether you recently installed the thermostat or it was previously functional and stopped.
Users of Ecobee thermostats frequently have issues with improper or faulty wiring, too little electricity, tripped circuit breakers, blown fuses, broken sensors, overheating, or erroneous settings. Fortunately, you don’t need to call an HVAC specialist to diagnose and repair most of these issues.
Why Is My Newly Installed Ecobee Not Turning On?
Follow the instructions if your Ecobee was freshly installed and won’t turn on to learn more about the potential root of the problem.
- The Power Wiring
There are several reasons your Ecobee thermostat could not work, but the wiring is often the issue. Poor wiring may prohibit the circuit from powering your thermostat. The screen will be dark or blank while the thermostat is not operating.
- Absence Of C Wire
Always keep in mind that Ecobee thermostats need a C-wire to be powered. Without this, you might face many problems while attempting to power your thermostat.
- The Terminal Connections
After installing your power extension kit, verify that the wire on your thermostat is connected to the appropriate terminal on the HVAC control board. The wrong terminal connection might be why your thermostat is not turning on.
- Thermostat Placement On The Backplate
The thermostat may not turn on if the thermostat wires are in the way of the Ecobee’s connection to the backplate.
- Improper Set-Up
Make sure the furnace’s lid panel is properly closed. Some furnaces contain a safety switch that, if the cover panel is not properly closed, turns off power to the device. You should also take note of that.
- A green flash on the light bar will appear to show that the Ecobee Smart Thermostat is powered on for voice-activated models. Contact Ecobee support if the light bar flashes green, but the thermostat does not turn on, for more help.
- Examine the fuse on the actual control board for the furnace. The fuse has to be replaced if it has blown.
- A short in the C wire can also stop the thermostat from operating if the Power Extend Kit is not being used.
Why Is My Previously Working Thermostat Not Turning On?
A previously functioning thermostat that suddenly goes black is an indication that there is not enough voltage getting to the thermostat. If the HVAC serves as the Ecobee thermostat’s power supply, any disturbance to this power source will cause the thermostat to lose power.
Check the voltage at the Ecobee between RC and C using a multimeter. The thermostat cannot be powered by voltages lower than 24 volts. Here are some more causes for the thermostat to have ceased functioning if this is not the problem.
Tripped Circuit Breaker Or Blown Fuse
Always keep in mind that if a thermostat starts to fail after previously operating without issue, a fuse or circuit breaker may have tripped.
Solution To My New Ecobee Thermostat Not Turning On
Now that the possible reasons for your Ecobee thermostat not turning on has been listed, we can proceed with the solutions to solve the abovementioned issues.
- Solution To Poor Wiring
Turn off all of the electricity to your HVAC equipment and the thermostat to fix a wiring problem. Verify if the thermostat’s wiring is linked appropriately and that all wire connections are firmly made. For information on the proper wiring configuration, you can easily consult your Ecobee handbook.
You can look on the Ecobee website if you can’t locate your handbook. Search for your Ecobee model’s online handbook and contrast the wiring instructions with how your thermostat has been wired. After that, you can proceed by making corrections where needed.
Except for the Ecobee3 Lite, your Ecobee thermostats typically require an R/Rc/Rh cable to power the device. This wire’s connection to the unit’s RC terminal is required.
- Solution To The Absence Of C Wire
Check to see if a wire is attached to the thermostat’s C terminal. If not, search the wire bundle for an unused wire and attach it to both the appropriate C terminal on the thermostat and the C terminal on the HVAC system.
Sometimes there may be wires marked “R,” “G,” and “Y” instead of a spare C-wire. Then a Power Extender Kit is necessary (PEK). The PEK can be installed and wired by you, but if you don’t think you have the requisite expertise, an HVAC professional can do it for you.
- Solution To Wrong Terminal Connection
This can be easily fixed. All you have to do is to be sure that the wire on your thermostat is connected to the appropriate terminal on the HVAC control board. The following should apply.
- R wire >> RC terminal
- G wire >> C terminal
- W wire >> W1 terminal
- Y wire >> PEK terminal
- C wire >> C terminal
- Solution To Thermostat Placement On The Backplate
Pull the thermostat wires backward to tuck the pins fully into the backplate to fix this. When you complete it properly, you will hear a click. Furthermore, there must be no gaps between the backplate and the Ecobee.
- Solution To Tripped Circuit Breaker Or Blown Fuse
To make sure that the circuit supplying the furnace is not tripped, inspect your breaker box. If so, switch it back on to give the furnace electricity again. The thermostat should restart itself as a result.
Open the panel on your furnace to see the control panel where the cables for your thermostat are linked. And make sure the fuse is not blown by checking it.

Why Is My Ecobee Thermostat Not Turning On The Air Conditioning?
The Ecobee thermostat frequently fails to switch on the air conditioning, which is a concern. There are different reasons for this but the major reason will be discussed below.
- Build Up Of Water
The Ecobee thermostat may turn off the electricity to the air conditioning if there is a buildup of water in your HVAC system. This is a safety feature of Ecobee thermostats, not a flaw in the thermostat itself.
- Solution To Build Up Of Water
Look for water leaks and excessive moisture surrounding the air conditioner to establish if a water buildup is the cause of the thermostat failing to activate the air conditioning. The drainage system could be blocked if it is damp. Clean the blocked drainage system, then turn off the electricity to the thermostat and the air conditioner.
Frequently Asked Questions
Does An Ecobee Thermostat Need Batteries?
Unlike the Ecobee3, which is powered by the common wire in your HVAC system, the Ecobee4 thermostat is hardwired (C-wire). However, a CR2032 coin-cell battery-powered wireless sensor is included with the Ecobee thermostat.
How Can I Reset My Ecobee Thermostat?
Depending on what you need to do, there are three basic ways to reset your Ecobee thermostat.
- Reset Schedule And Preferences
By doing this, you will lose your normal Schedule as well as any preferences you have created for things like date and time, location, hold action, temperature range, etc. The thermostat will still remember the setup of your equipment. Additionally, your Ecobee user account won’t be erased.
To Proceed, simply select Settings > Reset > Reset Schedule and Preferences from the thermostat’s main menu.
- Reset Registration
Your Ecobee user account is deleted after this reset. You must perform this reset if you need to update the email address associated with your Ecobee account. You can re-register using your new email address and password after the reset.
