Chances are that you’re not setting the temperature settings on your Trane thermostat correctly.
If that’s the problem, you should manually configure the temperature of your device until your system starts cooling.

Note: Keep in mind that if you keep the thermostat at Auto mode, this may be the reason why your cooling is not working.
If adjusting the temperature manually didn’t work, you should perform a power cycle on your thermostat to fix the issue.
The power cycle practically discharges the electricity out of your Trane thermostat and is done by ejecting and then inserting the batteries.

One of the reasons that your Trane thermostat and HVAC system don’t cool is clogged air filters.
Over time, the air filters in your HVAC system setup will get full of dust, and dirt and may even get clogged, hence, cooling will become impossible.
Here’s how to clean your HVAC system’s air filters in easy steps:
- First, go over to your thermostat and disable any mode you’ve activated.
