How to Fix Amazon Smart Thermostat Not Cooling

Since your Amazon Smart Thermostat is a smart device, it can be prone to temporary software issues. The quickest way to get rid of these is to restart your thermostat.

You can turn it off by pulling the plug from your circuit breaker. Turn it back on again to get your thermostat up and running.

If this step does not resolve your cooling issues, here are the other steps you need to try:

Solution #1: Check Your System’s Compatibility

You want to know the type of cooling system you can control 100% of the time. Some systems, like furnaces, don’t have cooling capabilities.

However, if your thermostat is linked to heat pumps or ACs, you should be able to cool your room or home in no time.

Here’s how to know your HVAC is compatible with the Amazon Smart Thermostat:

1. Check for voltage warnings on the thermostat wires.
2. Check for wires labeled L1 and L2.
3. Check if the wires have stranded ends.
4. Check if wires are connected by wire nuts.

Note: If you see any of these signs, Amazon Smart Thermostat won’t be able to work with your HVAC.

Solution #2: Check the Wiring for Loose Connections

After making sure that your smart thermostat and HVAC can pair up with it to cool your home, you want to watch out for loose connections.

Smart thermostats usually have several wires that need to be connected properly.

Some of these wires bring power from your HVAC to your thermostat. Other wires control the cooling or heating systems of your thermostat. There are even wires that separately control the fan.

Here’s how to secure loose or damaged connections:

1. Open the front faceplate of your car.
2. Take a picture of your current wiring setup.
3. Remove one wire at a time.
4. Connect the wires properly to their terminal.

Tip: If you forgot how to reconnect the cables to the terminals, use the picture you took before you start working on your thermostat.

Solution #3: Disconnect the C Wire

Not all smart thermostats need the C wires to function. The C wire provides power from your HVAC into your thermostat.

However, on some newer models, you don’t have the C wire plugged into the terminal for your thermostat to work.

One of the ways that you can resolve your Amazon not cooling is by disconnecting the C wires.

If the absence of the C wires does not cause it to play and reset. You can leave it unplugged and check if your thermostat powers up:

Here’s how to disconnect the C wires on your thermostat:

1. Open the front faceplate of your thermostat.
2. Find the wire that’s labeled C.
3. Pull it out of the terminal.
4. Slowly insert it into the terminal marked C.

Note: Make sure to turn off the power supply to your HVAC and thermostat to avoid any accidents.

Solution #4: Set Your Temperature Schedule and Activate It

You may also not have set your home temperature schedule on your Amazon Smart thermostat.

You could have also inadvertently turned it off while changing the settings on your thermostat.

Now that the seasons have changed, it’s time to set your temperature schedule that includes any cooling activities during the times the day turns unbearably hot.

It’s easy to enable this setting and completely forget about it.

Here’s how to activate your temperature scheduling:

1. Open the Alexa app on your phone.
2. Select Devices, and go to Thermostats.
3. Select the Thermostat you’re currently using.
4. Choose Settings, then Thermostat Schedule.
5. Enter the times and temperatures you want to set your thermostat.

Note: You can still change your thermostat’s temperatures even with scheduling activated.

Solution #5: Check Your R Wire

If your C wire provides power to your thermostat, the R wire ensures that your heating and cooling system is provided enough power.

For most thermostats, your R wire is split into two. Rh and Rc for both R heating and cooling.

The good news is that if your wires are already labeled, there’s no need to think about where to connect the wire.

The R label on your thermostat should be front and center, ready for you to use it.

Here’s how to connect your R wires properly:

1. Open your thermostat’s faceplate.
2. Check the number of R wires your thermostat has.
3. If you only have 1 R wire, pull up your thermostat’s R jumper.
4. Plug the wire into the R terminal.

Note: If you have two R wires, you’ll need to pull the jumper down and connect both wires to the two R terminals.

These surefire solutions should get your Amazon Thermostat cooling your room or home again.

If that’s not the case, you can always contact Amazon customer support or get a professional to look into your issue.
