Here are some reasons why your ecobee internal temperature sensor might not be working
1. The sensor is not properly connected to the thermostat.
This is the most common reason why ecobee internal temperature sensors fail. To check if the sensor is properly connected, remove the sensor from the thermostat and then plug it back in. If the sensor is still not working, try connecting it to a different port on the thermostat.
2. The sensor is damaged.
If the sensor is cracked or broken, it will need to be replaced. You can purchase a replacement sensor from the ecobee website or from a local hardware store.
3. The sensor is blocked by something.
If the sensor is blocked by furniture, curtains, or anything else, it will not be able to read the temperature accurately. Make sure that the sensor is clear of any obstructions so that it can read the temperature of the air in the room.
4. The battery in the sensor is dead.
If the sensor is battery-powered, make sure that the battery is not dead. You can replace the battery with a fresh one to see if that fixes the problem.
5. The thermostat is not set to use the sensor.
To check if the thermostat is set to use the sensor, go to the thermostat’s settings menu and select “Sensors.” Make sure that the sensor that you are having trouble with is enabled.
6. The sensor is in a location that is too hot or too cold.
The ecobee internal temperature sensor is designed to read the temperature of the air in the room. If the sensor is in a location that is too hot or too cold, it will not be able to read the temperature accurately. Try moving the sensor to a different location and see if that fixes the problem.
7. The sensor is not calibrated properly.
The ecobee internal temperature sensor can be calibrated to ensure that it is reading the temperature accurately. To calibrate the sensor, go to the thermostat’s settings menu and select “Sensors.” Select the sensor that you want to calibrate and follow the instructions on the screen.
If you have tried all of these troubleshooting tips and the sensor is still not working, you may need to contact ecobee support for further assistance.
