Why is Ecobee Not Turning on Heat? (Fixed)

Is your Ecobee not turning on heat, and you do not know what is wrong with it? Various issues may be the cause of this problem.

However, you can always handle them without too many hassles and get back to your regular heating routines.

Kindly read below to get some working tips for this issue.

Your Ecobee thermostat will not turn on if the heat point on your thermostat is lower than the room temperature. Kindly set the ambient room temperature to be higher by one degree than the room temperature.

Reasons for Ecobee Not Turning On Heat

Your Ecobee may fail to turn on heat due to several reasons. These include:

• You set the heat point too low than your room temperature.
• Your thermostat settings are incorrect.
• The thermostat furnace is not receiving commands to turn it on.
• The thermostat is overheating.                     

Note: You can know that your Ecobee thermostat heat is on by checking if the display has an orange flame icon.

If the icon is white, your thermostat has no heat.

How to Fix Ecobee Heat Not Turning On

Fixing your Ecobee thermostat not turning on heat is not difficult.

You only need to apply some simple tricks, and you will have it working again. Kindly try the solutions we have listed below until the heat turns on.

Solution #1: Check the Thermostat’s Heat SetPoint

The heat set point on a thermostat is an essential factor to check, even though it seems very obvious.

The heat temperature setting on your thermostat should be higher with a range of at least a degree than the room’s temperature.

You can change the heat set point on the app or thermostat display. Before doing that, you will need to set your thermostat to Auto and heat mode.

The display on the screen has a slider that you can use to decrease or decrease the temperature to your preference.

Check the setpoint temperature displayed on the box under the current temperature.

Solution #2: Keep the Thermostat Away from Too Much Heat

Your thermostat furnace is at great risk when near too much heat. It can even go to the extent of causing a fire hazard.

However, Ecobee thermostats have a fail switch feature installed.

The switch turns off the furnace automatically when there is too much heat to prevent such incidents since it is actively activated.

You can do something with these parts to prevent overheating the furnace.

Vents:

The vents allow air to flow into the furnace. Ensure it has nothing that blocks it or else it may lead to an issue.

Air Filter:

You should replace the air filter in your Ecobee thermostat after every three months.

With time, they gather dirt and dust, which, if not taken care of, can lead to overheating, causing a malfunction in your heating system.

The Blower Fan:

Check it often to ensure it is not soiled or obstructed since it will not turn on the heat if in this state.

Evaporator Coil:

If this part is spoilt, it poses a risk to your system rebooting itself automatically, causing overheating. Ensure that you check it regularly and inspect it for any damages.

Solution #3: Make Sure the Furnace is On

When your thermostat is switched on, the furnace should generate heat.

So, if you do not turn on the furnace, the furnace will not do the necessary. Even after turning on the thermostat, turn on the furnace switch too.

You may turn on the furnace switch in some instances, but the heat still fails to turn on. Kindly try these solutions.

Reset the Furnace Switch

Go to your breaker panel, then switch on the breaker and switch it off again.

You may fail to notice the switch since it is not labeled. It looks like a regular switch on your thermostat.

Use the Extender Kit

The kit comes with the box once you purchase your thermostat. It acts as a C wire, hence completing the circuit.

It also provides the amount of voltage the system requires throughout the cables.

Solution #4: Change the Thermostat’s Settings

Your smart thermostat should change the temperature automatically. If it does not, you may need to do it manually.

1. Launch the Ecobee app on your mobile phone.
2. Navigate to the main menu, then settings.
3. Go to installation settings.
4. Scroll through to select Thresholds
5. Next select Auto heat /cool, then enable.

Once you follow the steps above, you should set the difference between the ambient room temperature and the temperature you wish to set for your room.

Go through the same process as above until you reach the Threshold option. Select Heat/cool Min Delta then set it to the desired temperature.

Solution #5: Link the Wire Properly to the Thermostat

If your current wiring is not appropriately linked to the thermostat, your thermostat will not work well.

And you will have issues such as heat not turning on since the commands you give do not reach the furnace.

The solution is to change the fan control from your thermostat to the furnace.

Perform the process using these steps:

1. Go to your Ecobee app and click on the main menu.
2. Click settings, then installation settings.
3. Maneuver to the Equipment, then Furnace.
4. Select ‘Fan control in heat mode,’ then HVAC.     

After you are through, the heat on your thermostat should turn on since the furnace can now receive commands.

Solution #6: Contact Support

Trying the above procedures should restore your thermostat heat. If none of the methods work, you may need to look for a working solution from the Ecobee customer support.

If your thermostat has a valid warranty, you can get it fixed within minutes.

Thus, Ecobee thermostat will not turn on the heat if the furnace does not receive a command or overheats. Change the fan control from the thermostat to the furnace to enable it to receive commands. Ensure that the vents, evaporating coils, and blower fan are clean to avoid overheating.
