The first step to take in order to fix a black screen on a Nest thermostat is to check the power source and make sure the wiring and correct connections are in working order. If there are no visible signs of damage to the power source wiring, you will need to power-cycle the thermostat.
To do this, simply locate the Nest circuit breaker in your home and switch it off for 30 seconds then switch it back on. Once the circuit breaker has been switched off and back on, wait a few minutes and check to see if the black screen is still present.
If the black screen persists, you can try to reset the Nest thermostat by pressing the thermostat ring and rotating the ring until you hear a clicking sound. The thermostat should then restart. If the black screen still shows after all of these steps, the Nest thermostat may need further investigation and a technician should be called.
What does a blank thermostat mean?
A blank thermostat typically means that the thermostat is either turned off or is in manual mode. If the thermostat is in manual mode, it may need to be adjusted in order for the desired temperature to be reached.
If the thermostat is off, it must be turned on and set to the desired temperature in order for the heating or cooling system to begin functioning. If a blank thermostat is displaying on the screen, it is important to inspect the system and set the thermostat correctly so that the desired temperature is reached.
A professional HVAC technician can also help inspect and diagnose the system, if necessary.
Why is my thermostat blank but fan works?

What do I do if my Nest doesn’t turn on?
If your Nest thermostat doesn’t turn on, there are a few things you can try to troubleshoot the issue.
First, check to make sure that the thermostat is correctly wired and that all of the wires are tight and making good contact with the screw terminals. If the wiring looks OK, try taking out the batteries and putting them back in again to see if that helps.
If that doesn’t work, check that there’s power to the thermostat. To do this, set your multimeter to the appropriate voltage setting, usually 200-300VAC, and then touch one probe to each of the thermostat’s screws (R, G, Y, W, etc. ).
If the power is on, the multimeter should read the full line voltage.
If the voltage is OK, then you probably have a faulty thermostat and will need to replace it. You can purchase a new Nest thermostat online or at your local home improvement store.
Finally, if the above steps didn’t solve your issue, you may need to contact Nest support for additional help.
