Nothing is more frustrating than a non-functioning cooling system on a hot afternoon. The thermostat is often the issue when a cooling system fails to start or function properly. Your Braeburn thermostat not cooling may result from defects or incorrect settings. Luckily, you don’t have to call a serviceman to troubleshoot many thermostat issues.

This article will take you through the whole troubleshooting process. There are various ways of solving the issue of Braeburn thermostat not cooling. Read on to find out why the thermostat is not cooling and what you can do before calling a serviceman.

Reasons Why Your Braeburn Thermostat Is Not Cooling

Your Braeburn thermostat may stop cooling for various reasons, including:

Incorrect Settings

The first thing you should do when you notice your Braeburn thermostat is not cooling is to check if it is set in the ‘cool’ mode. If it is set on the ‘heat’ mode, it will not turn on the cooling system. If it is on the ‘cool’ mode but still won’t turn the cooling system on, you should check its set point, which is the temperature at which it turns on the cooling system.

The cooling system will not turn on if the set point is too high. The temperature in your space would have to rise to the set point before the AC starts blowing cold air. The set point should be a minimum of 3 degrees lower than the indoor temperature.

Compressor Protection

If the thermostat does not work even after adjusting the set point, then it is likely that the compressor protection feature is on. Most Braeburn thermostats have the protection feature to prevent possible cooling system damage caused by short cycling. The thermostat should work five minutes after the compressor short cycle protection elapses.

Loose Wires or Incorrect Wiring

Your thermostat may not turn on the cooling system if its wiring is faulty. Check if there are any loose wires or faults in the wiring. Find the wiring terminal block on the thermostat by removing the cover, then ensure the heating and cooling stages are connected to the right terminals. Reconnect all the loose wires to the correct terminal. Refer to the user’s manual for directions on how to fix the wiring issues. Set the thermostat in the cool mode to see if it is working. If not, try the next step.

Unsuitable Installation

Your Braeburn thermostat may not be cooling because you installed it in the wrong place. For instance, if you install the thermostat near a window or an outside that you often leave open, it will receive an incorrect reading of your home’s temperature. In such circumstances, the thermostat misinterprets that your home does not need cooling. The same applies to installation in rooms prone to high-temperature fluctuations, like the kitchen and laundry.

Incorrect Temperature Readings

If incorrect temperature readings is the issue, you can easily uninstall and reinstall the thermostat in a different location. You can use the HVAC slide drive tool to install the thermostat. It is great for HVAC applications like installations and control work.

Low Batteries

Your thermostat could not be cooling because its batteries are low. If the unit uses batteries and it’s been over a year since you last changed them, a new set of batteries could be all you need. Get the right batteries for the unit, and remember you cannot mix old with new.
