Ecobee3 thermostat won’t turn on

Note: (this does not apply for newly installed Thermostat)

A sudden black screen usually indicates inadequate voltage goes to the thermostat if the ecobee was previously turned on and running well. The ecobee derives electricity from the heater, so a power failure at the thermostat would result in some disturbance to this power supply.

If you have a multimeter, you can test the voltage between RC and C at the ecobee—anything less than 24 VAC is insufficient. Check for the following:

  • A tripped circuit: To ensure that the circuit powering the furnace is not activated, search your breaker box. If it is, switching it back on and the ecobee can power back on to return power to the furnace.
  • A blown fuse on the furnace control board: To show the control panel where your thermostat wires are connected, open the panel on your furnace. Many devices on the board have a purple 3 or an orange 5 amp fuse. Check this fuse and make sure it is intact. A blown fuse is going to need to be patched. The ecobee is expected to turn back on until a blown fuse is replaced.
  • A tripped high-limit temperature sensor: This is usually followed by rebooting after a heat call at the thermostat, which can also result in a total lack of thermostat control.
  • A tripped float switch: This is usually accompanied by rebooting during a call for cooling which may result in a loss of power completely. Inspect your float switch/condensation pump/drip pan (located at the furnace) to see if there’s an excess of water or any blockage preventing the water from draining. Once this is addressed, the ecobee should power back on.

Why My furnace won’t turn on?

  1. No power to your furnace: Scan the main breaker panel for the furnace breaker switch. Try flipping it back on if the breaker has been activated.
  2. The furnace is overheating: An internal temperature sensor that acts as a protective valve is used in both furnaces. This sensor will malfunction if the furnace overheats, causing the heat to turn off. To help cool itself down, the furnace may continue to operate the fan blower, or may not perform any operation until the device is reset or has cooled down enough.

Furnaces commonly overheat as a result of the following conditions:

  • Running for long periods: The warmer it is outside, the more and longer your heater is going to work to keep your home inside warm. This can cause overheating of the furnace device in some situations. Lowering the fixed point of your heat temperature can help avoid overheating of your furnace system.
  • Reduced airflow: Clogged or dirty air filters reduce the airflow through the furnace, which can cause it to overheat. Check your filter. If the filter is clogged, it should be replaced or cleaned.

If your filter is clean or was recently changed, there could be a buildup of dirt on other elements in the furnace like the condensing coil or heat exchanger.  If changing or cleaning the filter does not resolve the high limit switch problem a technician may need to do a deep clean.

  • The thermostat is not calling for heat: Your ecobee thermostat will display a flame icon with an orange colored outline when it’s calling for heat. If the outline on the flame icon is white, the thermostat is not calling for heat.

Why My Ecobee3 Not Turning On Heat?

After setup the ecobee by default set the fan to energy efficiency, So what you to do change the settings accordingly as stated below.

  1. You need to go through an equipment setup to confirm the correct wiring and equipment is linked to the ecobee.
  2. Tap the control fan
  3. And switch the fan control to the furnace

Why My Ecobee3 Not Turning On the A/C?

  • Ecobee Is Not Set To Trigger Your A/C On: One reason why your Ecobee would not turn your air conditioner on is that it is not set up to trigger it on. 

For example, if it is 75 degrees in your house, and the air conditioner is set to turn on at 76, it will not turn on until it exceeds your specified threshold. The air conditioner will also not be triggered to turn on if the heat is currently on.

  • Drain Pain: There are traditionally two ways your HVAC system will drain water: drain pain or drain tube. Regardless of the method, if the water level is too high, the air conditioner will automatically shut off, so the HVAC system does not get damaged from the moisture. In these cases, your Ecobee will be unable to override this shut-off mechanism.
  • Clog in The Drain Line: If there’s a clog in your drain line, this can also be causing drainage issues that lead to your air conditioner not responding to your Ecobee. To fix this issue, you can unclog it DIY-style, or you can contact a professional to unclog your AC drain line.
  • A Full Drip Pan: Remove the pan entirely from the bottom of the HVAC unit to clean it. You can dump the drain pan out and wash it with mild soap and water before putting it back in place.

Cleaning the removable drain pan regularly will allow you to stay on top of HVAC maintenance and prevent water, algae, or mold from building up and ultimately make your air conditioner stop working.

What happens if ecobee loses WIFI connection?

The first thing to do is to verify if your wi-fi is working if your Ecobee has lost its wi-fi link. Try using a separate device to connect to the wi-fi. Restart the router by unplugging it, waiting a few minutes, and plugging it back in if it doesn’t work.

Once you have confirmed that the wi-fi is working for other devices, it’s time to try restarting your Ecobee. Turn it off, wait at least one minute, and then turn it back on again. Allow your Ecobee to boot up as normal.

Once the thermostat has booted up, open the Quick Change menu (cog icon) and check the Wi-Fi connection icon. If it isn’t connected yet, try closing the menu, waiting a few more minutes, and then opening again. If it still isn’t working, you can get further technical support by calling the Ecobee support hotline at 1-87

Why Are My Ecobee3 Sensors Detecting Temperature But Not Detecting Whether The Room Is Occupied?

You may have a sensor that was put together incorrectly. Ecobee discovered that some of their sensors had been incorrectly assembled. Basically, the covers were put on in the wrong position. If your sensor is detecting the temperature and connecting to the thermostat, but not detecting occupancy, this is probably what’s going on.

How Can I Get My Ecobee To Automatically Return To Its Regular Program After I’ve Manually Adjusted The Temperature?

With its default settings, it will remain at that temperature until you “clear” it if you manually adjust the temperature on your Ecobee thermostat. That ensures that if you don’t remember to reset it, at its regular time it will not change to its bedtime or away program.

However, you can change the preferences so that your Ecobee will go back to its regular program at the time of the next scheduled temperature change. On the thermostat, select Main Menu, then Settings. Next select Preferences. Then tap Hold Action. It will give you a range of options to choose for when you want your Ecobee to automatically return to its scheduled program.

My Ecobee3 touchscreen not working?

  • Simply unplug it from the wall
  • Wait 1 to 2 mins
  • And Plug back in

Report it to them by email if it happens again with a thorough explanation of what occurred, how many times it happened, pictures of the wiring set up behind the ecobee, your serial number of the ecobee (menu> about). And a screenshot of it happening, maybe.

  2. Go to Settings.
  3. Then go to Installation Settings.
  4. Select Thresholds.
  5. Then select Temperature Correction.
  6. Adjust the temperature reading to fit your needs.

if you are having an issue with calibrating heat and cool disabled and the above steps are unable to resolve it then you might need to see this..

Why Are My Sensors Showing N/A For Temperature And Occupancy?

If your sensors aren’t communicating with the thermostat, you’ll get N/A for both temperature and occupancy (see below if the temperature is showing up but the sensor can’t tell that the room is occupied). First, try moving your sensors closer to the thermostat to see if it can pick them up.

If that doesn’t work, try doing a hard restart of the sensor. Start by removing the back cover of the sensor and then taking out the battery. Wait for at least two minutes before putting the battery back in. Then wait another five minutes. Finally, check the thermostat again to see if the sensor is now communicating with it.
