Before we go into the various fixes for this problem, you want to make sure to reboot your Amazon thermostat. To reboot your device, you need to detach the faceplate from the wall mounts.
Wait for at least 10 seconds, then reattach the thermostat. This step should resolve any temporary issues your device might have.
In case restarting the switch does not work, we can proceed to the next steps:
This is a common issue experienced by most of Amazon’s Smart Thermostat users. Your device is turned on, but the display is stuck in Sleep Mode.
Waking it up should do the trick. You also want to check its brightness setting as it can be low, giving you a hard time looking at the content on screen.
Here’s how to check your thermostat’s display brightness:
- Tap on the display to wake it up.
- If it does not power on, open the Alexa app on your phone.
- Select your thermostat, then Settings.
- Tap on the Thermostat configuration.
- Choose Display brightness and increase it.
Note: Check if the display is simply inactive to save time before checking the display brightness.
If the circuit breaker of your HVAC and thermostat is not switched on, there will be no power running throughout the entire system.
Since there’s no power, your thermostat will not turn on. The good thing is that the fix is simple and all you need to do is turn it on.
Here’s how to turn on the circuit breaker switch for your HVAC and thermostat:
- Go to your circuit breaker panel board.
- Check for any switches that are turned off.
- Look for the circuit breaker switch for your HVAC.
- Move it to the ON position.
Note: You want to know if the switch for your HVAC and thermostat has tripped. If it trips often, you will need to have it checked out by a professional.
The R wire is responsible for powering up your Amazon Thermostat.
Your system will either have one or two of these wires, so you will have to ensure how many your system has. There’s no way to check this but to open up your thermostat.
Here’s how to make sure your R wire jumper switches are in the correct position:
- Remove the faceplate of your thermostat.
- Check the R jumper switch at the bottom right of the device.
- If your system only uses one R wire, connect it to the R terminal.
- If your system uses two R wires, connect them to R and Rc.
Pro Tip: If you only have one R wire, the R jumper switch should be in the UP position. If you have two R wires, it needs to be in the DOWN position.
If your previous thermostat had batteries, there’s a good chance you did not install the C wire properly into the control board.
The wire is responsible for supplying your thermostat with power 24/7 to support features like WiFi.
Here’s how to connect your C wire to your thermostat board the right way:
- Remove your thermostat’s faceplate to expose the panel.
- Look for the C wire on the control board.
- Connect one end of the C wire to your HVAC’s 24V Common port.
- Connect the other end to your thermostat’s C terminal.
Note: If you have an HVAC system that does not have a C wire, you might need to get an adapter kit to use it with the Smart Thermostat.
If you wired your thermostat correctly and provided it with power, but it still doesn’t turn on, you will have to restore it to factory settings.
This process should clear up any major issues, especially regarding the software. It will erase all the data on your thermostat, including your configurations and device settings.
Here’s how to reset your Smart Thermostat:
- On your thermostat, press the Up and Down Temperature buttons.
- Also, press the Mode button.
- Hold these 3 buttons for 10 seconds.
- Wait for rES to appear on the screen.
- Press and hold the Mode button for 5 more seconds.
Note: Wait for the reset process to finish so you can reconfigure your thermostat again.
