If your ecobee doesn’t turn on, please try these steps.

Check that all wires are properly inserted into the terminal blocks at the thermostat. Tug on the wires to ensure they are not loose.

Make sure your HVAC cover panel is closed. Some systems will not turn on if the cover panel has not been closed properly.

If you have only one R wire (either R, Rc, or Rh), make sure it’s inserted into the Rc terminal.

If you installed the Power Extender Kit, make sure you inserted the wires into the correct terminals.
