Ecobee Thermostat Not Turning On? Here’s What You Can Do

The Ecobee thermostat is one of the most widely used options on the market today. Smart home devices have become a crucial part of our everyday lives in the modern world.

The Ecobee thermostat may not switch on for certain customers despite its cutting-edge features and effective operation. This may cause pain and higher energy costs, and it can be unpleasant, especially in severe weather.

You can use this guide to troubleshoot wiring issues and other electrical issues that may be causing your Ecobee Thermostat Not Turning On, click without turning on, or reboot repeatedly.

Here is the possible Fixes and Reasons Against Ecobee Thermostat Not Turning On Problem

Ecobee Fixes Explanation
Check the Furnace Power Your Ecobee thermostat uses your furnace to produce heat; as a result, there won’t be any heat if the furnace isn’t running. Try toggling the breaker for the furnace electricity to determine whether power has been restored. If your furnace still won’t turn on, an electrician may be required to fix it.
Check the Heat Set Point If the heat isn’t coming on, check the heat set point first. At least one degree more than the present inside temperature is required. To modify the heat set point, use the app or the thermostat interface.
Adjust the thermostat settings. With Ecobee, users have a lot of control over their thermostats. For instance, the minimum temperature difference between the current temperature and the set point necessary to activate the heater can be changed. Additionally, you can specify a threshold for the temperature outside your house so that the supplemental heat turns off.
Investigate Possible Overheating of the Heating System A furnace automated shut-down trigger is included for safety reasons since an overheating furnace may catch fire. If the temperature inside reaches to an unsafe level, the furnace might turn off. The fan may keep running to help the boiler cool, but it won’t begin to heat your house until the boiler has cooled to a safe level.
Check Breaker and Heater Power Switch Your home breaker may trip if too much power is used or if lightning strikes nearby during a thunderstorm. It’s usually okay to flip it back and carry on.

Why Won’t The Furnace Turn On?

When an Ecobee thermostat doesn’t turn on the heat when it should, there are four possible reasons:

  • The thermostat is set at a lower temperature than the space is at right now.
  • Due to unique thermostat settings, the heat may not come on.
  • The furnace’s malfunction could be due to a power problem.
  • The boiler is ablaze.

Are you unsure whether the heat is on? Find the orange flame icon on the thermostat’s display. If the flame icon is white, there is no heat.

Keep an eye on the heat set point.

First, check the heat set point. At least one degree more than the present inside temperature is required. To modify the heat set point, use the app or the thermostat interface.

  • Make sure that your thermostat is set to Heat or Auto before you start.
  • The temperature can then be changed using the slider on the main display screen. The set point temperature will be displayed next to the current temperature.

Adjust the Thermostat Settings as Required

Users have a lot of power over their thermostats, which may surprise you. The minimum temperature differential between the current temperature and the set point that must exist in order to activate the heater can be changed. Additionally, you can program the supplementary heat to shut off when the outside temperature rises above the predetermined level.

Keep in mind that the Ecobee app or website cannot be used to modify these heat settings; only the thermostat interface can.

After performing the following actions, modify the heat threshold settings:

  • Settings” can be found under the main menu.
  • Select “Installation Settings” next.
  • Decide on “Thresholds.”
  • Change the parameters appropriately.

The temperature inside and outside of your home determines whether the heat is turned on by adjusting the heat threshold settings. 

For instance, lowering the temperature of the heat differential will speed the activation of your heater. However, keep in mind that changing these settings can increase your utility bills or put greater stress on your HVAC system.

Some customers reported that moving their fan control from the thermostat to the furnace had helped them when their heat wouldn’t turn on.

Follow these procedures to change the fan control: Furnace can be found under HVAC > HVAC Settings > Main Menu > Settings > Installation Settings.

Check Breaker and Heater Power Switch

Your home’s breaker may trip if excessive power is used or if lightning strikes nearby during a thunderstorm. It’s usually okay to flip it back and carry on.

1.  Check to see whether the breaker for the heater, air conditioner, or other device you’re having issues with is flipped in your home’s breaker box.

  • A breaker that frequently or repeatedly trips is a warning that there are significant electrical issues in your house. Contact a qualified electrician if this is a frequent occurrence with no other cause (such as an electrical storm) to prevent damage, loss, injury, or death.

2. Re-engage the breaker.

3. Wait 30 seconds at your breaker box to make sure it does not rapidly flip back.’

Timer 30 Sec

4. Give your thermostat one more minute to fully reactivate.

60 Seconds

To make sure it’s operating properly, try adjusting the temperature.

  • Your HVAC system is seriously damaged if the breaker trips soon after the heater or air conditioner goes on. To identify and fix the issue, get in touch with a local electrician or HVAC professional.

Heater Overheating

A sensor in your house heater can detect when it is getting too hot. This is a safety feature; if it trips, something is wrong with the operation and needs to be fixed.

While a professional will be needed for many elements of this, there are certain things you can check on your own.

AC Filters

Air Filter Clogged or Filthy

Your furnace has a filter that needs to be replaced or cleaned on a regular basis. Your furnace will have to work much harder and heat up more if it is blocked with dirt.

You might only need to inspect, replace, or clean your filter briefly.

Running the Furnace for Extended Periods of Time

Your furnace may get excessively hot if it is running nonstop because the temperature was raised or set very high during a cold snap. Wait for it to cool down before lowering the heat.

  • If this is a consistent problem, it indicates there is a deeper problem with your furnace, and will need to be serviced by an HVAC technician.

Check to see if your furnace is on.

When the heat mode is engaged, the furnace produces heat. Therefore, it makes sense that if your furnace is switched off, it won’t run. Consequently, confirm that your furnace is on.

You could occasionally find that this issue persists even when your furnace is running. Whether so, test out the following remedies to see whether they can be of assistance to you:

Try to reset the furnace by switching the breaker on and off at your home’s breaker panel. As an alternative, think about using the Power Extender Kit that comes with it.

The power extender kit completes the circuit and provides the required constant 24 V AC power supply by acting as a C wire. If these two are ineffective, try looking for the “furnace switch“; it should be close to the furnace and is sometimes mistaken for a conventional light switch because it is typically labelled.

Find this switch, turn it off for a little bit, and then turn it back on. If none of the aforementioned fixes work, it might be time to have your furnace inspected by a technician and, if necessary, replaced.

Issue Is Still Unresolved

If your ecobee thermostat is still shutting off or rebooting after performing these checks, there may be a more serious issue with the wiring, heating, or HVAC system.

Ecobee Furnace Turning On And Off

Most Likely

Furnace is overheating

All furnaces have a safety feature known as a high-limit temperature sensor that activates when the furnace starts to overheat. This sensor will trip if your furnace overheats, cutting electricity to your thermostat as a result. The boiler may turn on the fan to help it cool down, or it may wait to do any tasks until the system is reset or the boiler has cooled enough on its own.

A tripped float switch

Your furnace ought to include a float switch to stop flooding if water from condensation builds up. Condensation water that is not removed soon enough may activate the float switch, which will turn off the power to your thermostat.

Other Reasons for Ecobee Turning on and off


Low airflow

If your furnace continually turning off, there might not be enough airflow. Low airflow is a direct result of a number of problems.

  • Unclean air filters. If you don’t replace your air filters frequently enough, they’ll accumulate dirt and debris, retaining heat and eventually overheating the heat exchanger. Unless you have pets or allergies, you must change your air filters every 90 days. Every 60 days, or less frequently if your allergies are severe, air filters should be changed if you have pets or allergies.
  • A filthy blower wheel. A dirty blower wheel may be the cause of your furnace turning on and off too frequently. If the blower wheel’s air-pushing blades are covered in dirt, they won’t function as well and may even stop functioning altogether. By changing your air filters frequently, you can avoid dirt amassing on your blower wheel. If you don’t, the cost of fixing it can end up being high.
  • Air supply vents that are shut or blocked. Check your air vents to see if any are closed or otherwise blocked if your furnace keeps turning off. Even in the areas you don’t use, you should leave all of your vents open. Your heat exchanger won’t be able to transmit enough heat if it doesn’t receive enough air. As the heat increases, your furnace may eventually short cycle as a result.

Faulty thermostat

Your thermostat’s position might be the problem, the wiring might need to be updated, or it might be time for new batteries.

The temperature reading will be distorted if your thermostat is situated near a heat source, such as direct sunlight or a heat register, which will cause the thermostat to cycle on and off erratically.
