Ecobee is a home automation device which comes with a touchscreen display. This Ecobee3 Smart Thermostat can increase your home’s comfort and energy efficiency. It provides easy control over your HVAC system via Wi-Fi, mobile app, and Alexa voice service. The device uses various remote sensors for temperature sensing.

However, sometimes people might run into an issue of your Ecobee not turning on after install and you might wonder, “Why is my Ecobee not turning on after install?” We reveal the 7 main reasons why you might run into this issue!

Why Is Ecobee Not Turning On After Install?

If your Ecobee3 is not turning on after installation, there are several possible reasons. The first thing to check is whether there is the power to the wall outlet where you installed the thermostat. If there is power but no display or response from the thermostat, try plugging it into a different wall outlet and see if that resolves the issue. If this does not work, contact support for further assistance. Here are reasons why Ecobee not turning on after install.

7 Main Reasons Why Your Ecobee Is Not Turning On After Installation

1. Bad C-Wire Connection

The first thing you should try is making sure that your ecobee4 has power. If it doesn’t, then there’s no way it will turn on!

You can check this by connecting an extension cord to one of the outlets near where you installed your thermostat (be sure to use an extension cord with the proper wattage). Then connect one end of the extension cord to the outlet in question and the other end to a working wall outlet or power strip close by. This should give you some voltage reading on the back panel of your ecobee4, indicating whether or not power is coming into it.

2. Low Battery

If the Ecobee is not turning on after installation, it could be because of a low battery. The Ecobee thermostat has a backup battery that will last up to 24 hours if there is no power. If your thermostat was recently installed, or if you haven’t updated its firmware, then the thermostat might not turn on immediately. If you’re having problems getting your Ecobee to turn on after installing it, try the following steps:

  • Make sure that you have installed the battery correctly.
  • Make sure that the wall plate is screwed in tightly and that all wires are correctly connected.
  • Check to ensure power is getting into your home (i.e., check the breakers).
  • If you are using a C-wire (standard wire) with your system, ensure that it is connected properly and that power is going through it.

3. Power Extender Kit Not Connected Correctly

There are a few reasons why your Ecobee3 or Ecobee4 is not turning on after installing it. The most common cause is that the power extender kit is not connected correctly. To troubleshoot this issue, please follow the steps below:

  • Ensure that both ends of the power extender kit are plugged into the wall outlet and your thermostat.
  • If you have two power extenders and only one is plugged in, it will not work. If you have three power extenders and only two are plugged in, it will still work, but only two thermostats can communicate with each other, which may cause some issues.
  • If you have three power extenders and all three are plugged in, they should all blink green. If they do not blink green or if only one or two blink green, then there may be a problem with the wiring or configuration of your system (please consult an HVAC professional).

4. Defective Thermostat Unit

The most common reason why a new thermostat may not turn on after installation is that it is defective. Thermostats are electronic devices that may malfunction due to power surges or other factors. It might be inadequate if you have installed a new thermostat and it still does not work. This can happen if an error occurs during manufacturing or the device is damaged during shipping or installation.

Another possible cause for your Ecobee not turning on after installation could be wiring damage caused by improper installation process or mishandling during the shipping process from manufacturer to seller and finally from the seller to buyer’s home.

5. Incompatible HVAC Systems

You should check when Ecobee won’t turn on and whether the thermostat is compatible with your HVAC system. The Ecobee3 and the Ecobee4 are compatible with most HVAC systems and are easy to install. If you have an older model of the thermostat, you might need to replace it with a new one if you want to use the Ecobee4 or other models by this company.

If your current thermostat was made before 2007, it’s not compatible with any intelligent thermostats and won’t work with any smart devices such as smartphones and tablets. You should consider replacing these older devices with newer ones if you want them to work together correctly.

6. Air Handler Issue

The air handler is a device that moves warm or cool air through your home. It works with ducts and vents to heat or cool different areas of your house at other times. If there is an issue with your air handler, it can also affect your Ecobee thermostat’s operation. Symptoms of Air Handler Issue

  • If you are seeing any of the following symptoms, then there may be an issue with your air handler:
  • Your Ecobee thermostat is not turning on when it should (i.e., when you press the “On” button).
  • Your Ecobee thermostat turns on but then turns off automatically within a few minutes to several hours (depending on how long it takes for the temperature in the room to reach its target temperature).

7. Incorrectly Sized and Installed Wires

The wires in your home may not be sized correctly or installed correctly, which can cause the Ecobee not to turn on after installation. The wiring needs to be appropriately sized, so there is enough power to get through all the devices in your home. If there isn’t enough power, you may have problems with your ecobee turning itself on or off at the wrong times, which can cause more damage than just having a defective device.

Suppose you have problems with your ecobee turning itself off at night when you want it to stay on longer. In that case, something is probably wrong with your electrical system that needs to be fixed before replacing parts like an ecobee will fix the problem.

Wrapping Up

If your ecobee is not turning on after installation, the power cord was likely not plugged in correctly. Ensure you have a good connection between the unit and its power source. Make sure that there are no loose or broken wires. If you are using an extension cord, ensure that it is rated for at least 15 amps, as this will help reduce the chance of overloading your circuit breaker or fuse box.
