Incorrect settings or defects on your thermostat can impact your home’s cooling system. So if your Braeburn thermostat isn’t turning on your cooling system, chances are it’s not set correctly, worn out, or faulty.
But fortunately, you can troubleshoot several thermostat issues yourself without calling a serviceman.
So in this post, I’ll walk you through the steps to troubleshoot cooling issues with your Braeburn thermostat. Let’s begin!
How to Troubleshoot a Braeburn Thermostat that Isn’t Cooling
1. Check that Your Thermostat is Set to Cool
As you probably know, your thermostat must be in COOL mode to control the cooling system. So if your thermostat won’t turn on the AC, the first step to troubleshooting this issue is to check that your thermostat is set to COOL mode.
If OFF or HEAT is shown in the display, it means your cooling system is off at the thermostat, and you’ll have to switch it to the COOL position to turn on the cooling system.
After switching to COOL mode, press the Up Arrow button on the thermostat until the setpoint temperature is a minimum of 3 degrees lower than the current room temperature. Your cooling system should start working within seconds.
If it doesn’t work in seconds, chances are the Compressor Protection feature is in effect (if your thermostat has the feature). Wait 5 minutes for the compressor short cycle protection period to elapse. This feature is included in most Braeburn thermostat models—to prevent potential damage to the cooling system from short cycling.
Continue to the next step if the issue persists.
2. Incorrect Temperature Readings
Your Braeburn thermostat may shut off automatically if it’s getting an incorrect temperature reading in your home. Of course, your cooling system won’t work if the thermostat is in OFF mode.
Issues like this could happen if your thermostat is not installed in the correct position. For instance, locating your thermostat close to a room with notable temperature fluctuations (such as kitchen or laundry room) or on a wall that faces outside can cause incorrect temperature readings.
If this is the case with your thermostat, you’ll have to uninstall it, then reinstall it in a different location to see if that solves the cooling issues.
3. Check Your Thermostat Wiring
Loose wires or incorrect wiring can also impact your heating and cooling system. So if your thermostat won’t turn on the cooling system after trying the above troubleshooting steps, the next thing you want to do is check if there are loose wires or incorrect wiring.
To do this, locate the wiring terminal block on your Braeburn thermostat (you may have to remove the cover) and ensure that the heating and cooling stages are connected to the correct terminals. Also, reconnect any loose wires and make sure you connect to the appropriate terminal.
If you’re not sure how to fix wiring issues on your thermostat, refer to your user manual and follow the guidelines on the wiring diagrams.
Next, try to set your thermostat to the COOL position to see if it turns on your cooling system.

4. Replace Batteries
If your Braeburn thermostat runs on battery power, try replacing the batteries, as low batteries could also cause cooling system issues.
Ensure you get the correct batteries (non-rechargeable alkaline batteries) and do not mix new batteries with old ones.
5. Reset Your Thermostat
Now try to reset factory default settings on your Braeburn thermostat if the above troubleshooting steps couldn’t fix the cooling issues. Restoring default settings usually helps to fix incorrect settings/bugs obstructing the cooling system settings.
To reset your Braeburn thermostat, find the Reset button on the front of the thermostat (a round hole), then press it gently using a paper clip, a pin, or any similar object.
Now your thermostat is reset, and that should fix the cooling issues you’re having with it. But if not, it appears that the problem is from your AC and not the thermostat. Keep reading for other troubleshooting tips to try.
6. Check and Fix Issues with the Cooling System
As mentioned, if the issues persist after trying all the troubleshooting steps above, chances are your cooling system is faulty. In that case, here are some troubleshooting tips to try:
- Check and Replace Blown Fuses: Locate the fuse box on the outside of your home, then pull out the fuses and perform a continuity test using a multimeter. Next, replace any fuse that isn’t working properly. Ensure you turn off the AC and power supply before accessing the fuse box.
- Check the AC Motor: Sometimes, your air conditioner may not turn on if the motor isn’t charged. So check to see if the capacitor that charges your AC motor is faulty and replace it. You can use a multimeter to perform the test.
- Check the Condenser Unit: Sometimes, minor issues like unplugged condenser cord/wires can prevent your AC from turning on. These wires (if unplugged) will prevent the flow of electricity to your AC, causing the AC not to turn on. So check the cord coming out of your AC to see if it’s unplugged. If so, plug it back in.
- Check the Air Filter: Your AC may completely stop cooling your home if the air filter is clogged with dust and debris, as this blocks airflow. So check to see if this is the issue, then replace the air filter.
Note: Troubleshooting your air conditioner may require some precautions to avoid electrocution or damaging the AC. Always turn off your power supply before running any check on it. And if you’re not sure how to go about this, call an HVAC expert to help you.
As you can see, there may be several reasons behind the cooling issues you’re having with your Braeburn thermostat. Perhaps you’ve set the thermostat incorrectly or a bug. Of course, you can fix these issues with the above troubleshooting tips.
However, the fault could sometimes come from the AC and not the thermostat. So if your thermostat isn’t turning on the AC after troubleshooting it, try to troubleshoot the air conditioner.
But note that some issues with the AC might be complex, so you want to have an HVAC expert run a check on the AC—if you’re not sure of doing it yourself correctly.
